FAQ

Q: What is the switching power supply？

A: Switching power supply is a type of power module that is widely used in various electronic devices. The reason why it is called "switching" is because it contains Schottky diodes with switch characteristics. These diodes have a very high switching frequency and can switch on and off thousands of times in a short period of time. Each time they switch, they can provide power and current output for the device. Switching power supply plays an important role in general integrated circuits. This type of power supply is highly efficient and reliable, making it a popular choice for many electronic applications. So, let's appreciate the benefits of switching power supply and the positive impact it has on our daily lives!

Q: What switching power supplies do we commonly use？

A: 1. Single output switching power supply (provides one set of voltage and is commonly used with power ranging from 15W-400W).

2. Dual output switching power supply (can simultaneously provide two sets of different voltages).

3. Triple output switching power supply (can simultaneously provide three sets of different voltages).

4. Quadruple output switching power supply (can simultaneously provide four sets of different voltages, but is not commonly used).

5. Compact switching power supply (has a smaller casing compared to the standard S-series, with similar parameters and performance).

6. High-power switching power supply (has a power output of over 500W, mainly used in industrial applications).

7. Rainproof switching power supply (has the same functions as the single output switching power supply, but with a different casing with tilted holes that prevent rainwater from entering, making it suitable for outdoor use).

8. Waterproof switching power supply (has a long and enclosed casing that is waterproof and rainproof, but with less efficient heat dissipation due to its enclosure).

9. Rail-mounted switching power supply (has a different installation method with plastic casing and is mounted on a rail track for use). In terms of output voltage, commonly used ones include 5V, 12V, and 24V, followed by 9V, 15V, 36V, 48V, and so on. Overall, switching power supplies provide a range of options to suit various needs and applications.

Q: what should you pay attention to when using switching power supply？

A: 1. Before using the power supply, make sure to confirm that the input and output voltage specifications match the nominal values of the power supply being used.

2. Before turning on the power, check if the input and output leads are connected correctly to avoid damaging the user's equipment.

3. To ensure safety and reduce interference, make sure the grounding connection is reliable.

4. Please note that frequent power on/off switching will affect the power supply's lifespan.

5. The working environment and load level will also affect the power supply's lifespan.

6. Check if the installation is secure, if the screws are in contact with the power supply board components, and measure the insulation resistance between the casing and the input/output to prevent electric shock.

7. Multi-output power supplies generally have main and auxiliary outputs with the main output having superior characteristics. Typically, the output current of the main output is larger. To ensure output load regulation and dynamic performance, it is generally required that each output has at least 10% load. If using the auxiliary output instead of the main output, be sure to add appropriate dummy load to the main output. Please refer to the corresponding specifications for specific models.

Q: How to choose the right switching power supply？

A: 1) Choose the appropriate input voltage specification.

2)Select the appropriate power. To increase the lifespan of the power supply, a model rated at 30% more output power than required can be chosen.

3) Consider the load characteristics. If the load is a motor, light bulb, or capacitive load, a suitable power supply should be chosen to avoid overload when powering on. If the load is a motor, consideration should be given to the voltage reverse that occurs when stopping.

4)In addition, the operating environment temperature of the power supply and the presence of additional heat dissipation devices should be considered. High temperatures may require reduced output for the power supply. The reduction curve of the output power due to the environment temperature should be considered.

5)Select various functions according to the application needs, such as protection functions (overvoltage protection, over-temperature protection, over-load protection), application functions (power supply normal, power supply failure), remote control function, remote measurement function, and parallel function. Special functions include power factor correction (PFC) and uninterruptible power supply (UPS).

6)Select the necessary safety regulations and electromagnetic compatibility (EMC) certification.

Q: Are switching power supplies dangerous for home use?

A: There are definitely risks involved, as someone who specializes in this field, but the key is to keep children away from it. After all, the wiring carries a high voltage of 220v, although the output is low voltage and not a problem. It's also important to keep the power source dry and free from debris. Good quality power sources come with protection features to prevent any major issues. However, if the quality is poor, it's hard to say. Overall, remember to stay positive and take necessary precautions to ensure safety.

Q: What is a built-in power supply?What is an external power supply?

A: The built-in power supply means that the power supply is embedded in the lamp body. Special attention should be paid to the size and temperature resistance of the power supply. For example, for our defined panel light power supply, such as the GIRxxxYM series, if a customer's lamp body can accommodate this product, and it is used inside the lamp, and the temperature also meets our specifications for quality assurance requirements (please note that our quality assurance is based on the actual Tc temperature when the power supply is operating, not the Tc temperature marked on the power supply housing), and it also meets the customer's environmental application requirements, it can also be used internally. However, it is important to note that many lamps (especially waterproof lamps and strip lights) have completely sealed lamp chambers, and the internal environment temperature is very high when working. Non-gel-coated plastic shell power supplies, such as the GIRxxxYM and GIFxxxYA series, are not suitable for use in these types of lamps. If the customer wants to use plastic shell power supplies for waterproof lamps or strip lights, the customer must be informed of this precaution. We recommend that customers use long strip iron shell power supplies specially designed for waterproof lamps and strip lights, such as GMRxxxYE and GMRxxxYSII, to avoid quality problems and complaints caused by customers' misuse of power supplies, which can cause unnecessary trouble. If the customer's lamp body is a metal shell, insulation measures need to be taken between the power supply and the lamp chamber when the power supply is embedded. The external power supply is placed outside the lamp and generally has no size requirements. It can be fixed or not, depending on the specific situation. The external power supply must have insulation and terminal dust protection. If it is used in a humid environment or outdoors, the power supply needs to have the corresponding waterproof rating.

Q: The difference between constant current power supply and constant voltage power supply？

A: According to circuit design, LED power supplies can generally be divided into constant current power supplies, constant voltage power supplies, constant power supplies, and constant current ICs. Today, we will be discussing the most commonly used LED power supply, which is the constant current power supply. The output current of a constant current driver is constant (with an accuracy of ±5%), while the output voltage varies within a certain range depending on the load resistance. As the load resistance decreases, the output voltage also decreases, and as the load resistance increases, the output voltage also increases. For example: AC100-240V DC30-40V 800MA (±5%). On the other hand, a constant voltage driver means that once the parameters of the voltage-stabilizing circuit are determined, the output voltage will remain fixed, while the output current will vary depending on the load. For example: AC100-277V DC24V 0-1250mA. Let's stay positive and focus on the amazing capabilities of these power supplies!

Q: How to understand class I and Class II power supply？

A: According to European standards, Class I power supplies have protective grounding, while Class II power supplies do not have protective grounding. For our Class II power supplies, which are actually used in Class I lighting fixtures where the power supply is not grounded but the fixture housing is grounded, special attention should be paid to whether the overall lamp can meet certification requirements for conduction and radiation. According to American standards, Class 2 power supplies require that the power supply must be an isolating power supply, with output voltage below 60Vdc, power less than 100W, and abnormal power less than or equal to 150W. American Class 2 is equivalent to European SELV. In European standards, as long as the output voltage is less than 120Vdc, it meets SELV standards. Please note that in European standards, it is I and II, while in American standards, it is 1 and 2. We should stay positive and upbeat in this article, avoiding negative content.

Q: What are the functions of LED power supply？

A: effect:

①AC to DC

② Supply the current size and voltage range required for lamps

③Provide circuit safety protection for lamps

④Electromagnetic compatibility processing, filtering processing

⑤Other intelligent controls, etc.

Q: Classification of LED power supply？

A: Classification:

by isolation method Isolated Power:

The conversion process is "electro-magnetic-electric".

A transformer is used to pass the high voltage through the transformer to reduce the voltage to a lower voltage and then rectify it into a DC output.

Non-isolated power supply:

The conversion process is "electricity-electricity"

Use high voltage to reduce the voltage through inductors and other components and then rectify it into DC output.

Category: by installation location

Built-in power supply: built into the lamp cavity. If the lamp is a metal shell, insulation measures must be taken between the power supply and the lamp cavity.

External power supply: Place it outside the lamp. It can be fixed or not fixed depending on the situation. The outer shell must be insulated. If it is used outdoors, it needs to be filled with glue and waterproof.

Q: What does a switching power supply power supply consist of？

A: The switching power supply is composed of a full-wave rectifier, a switching tube, an excitation signal, a freewheeling diode, an energy storage inductor and a filter capacitor. In fact, the core part of the switching power supply is a DC transformer.

Q: What causes the output voltage to be low？

A: 1) When multiple loads are connected in parallel in an output stage, there may be instances where one load requires a large transient current, causing a momentary voltage drop that affects the other parallel loads.

2) If the output line is too long or thin, it can result in significant line losses, leading to voltage drops between the power supply module and the true load, resulting in lower voltage at the load terminals.

3) The forward voltage drop of the reverse protection diode may be too high, typically ranging between 0.2-0.6V. If the power supply module outputs a voltage of 5V, the high forward voltage drop of the diode may cause the voltage in the subsequent circuitry to drop, leading to malfunction.

4) A large input filter inductance in the external circuitry of the module may increase the internal resistance, leading to increased current suppression. When the load suddenly becomes heavier, the current may not be able to supply the load, causing a lower voltage at the load terminals.

Q: How to solve the problem of low output voltage？

A: Solution:

1) Add a large capacitor or switch to a higher power input source at the output end;

2) Adjust the wiring, increase the wire cross-sectional area or shorten the wire length to reduce internal resistance. If the power module has a Trim function, adjust it to increase the output voltage to offset the voltage drop caused by line loss;

3) Switch to a diode with lower conduction voltage drop;

4) Reduce the value of the filter inductor and lower the internal resistance of the inductor. Let's stay positive and find solutions to overcome this problem.

Q: What are the causes of high output voltage？

A: 1) Hot-plugging and powering on at the input terminal of the power module can result in high voltage spikes and surge currents, which may cause damage to modules with poor voltage resistance.

2) When the output load is too light, less than 10% of the rated load, some non-linear voltage stabilization power supply products may be unaffected, but it can affect the performance of the subsequent stage, such as lower efficiency and module overheating.

3) Voltage spikes from the front-end power supply can lead to high input voltage or interference voltage, and electromagnetic compatibility can easily cause input voltage to be high, such as lightning strikes, surge, and group pulse. Let's stay positive and focus on the solutions.

Q: How to solve the problem of high output voltage？

A: Solution:

1)Ensure that the output terminal is not less than 10% of the rated load. If there is often a no-load phenomenon in the actual circuit, add a dummy load with a rated power of 10% to the output terminal.

2) Replace a reasonable and stable range of input voltage sources. If there is interference voltage, consider adding TVS tubes or voltage regulators to the input terminal. An EMC peripheral circuit can also be added.

Q: What factors have a major impact on power supply output noise？

A: 1)The power module is located too close to sensitive components in the main circuit.

2)Coupling capacitors were not connected to the power input terminals of noise-sensitive elements in the main circuit.

3)Interference between the difference frequencies of output power modules in multi-channel systems.

4)Improper ground handling.

5)Excessive noise at the input terminals of power modules which was not processed and directly coupled to the output terminals. We can solve these issues by implementing appropriate measures to ensure proper signal flow and reduce interference in our circuits. With careful attention to detail and a proactive approach, we can achieve optimal performance and reliable operation of our systems.

Q: How to solve the problem of too much noise during power supply operation?

A: Solution:

1)Place the power module as far away as possible from the main circuit's sensitive components or modules, and isolate them from the main circuit's sensitive components;

2)Connect a 0.1μF decoupling capacitor to the power input of the main circuit's sensitive components (such as A/D, D/A, or MCU);

3)Use a multi-output power module instead of multiple single-output modules to eliminate beat interference;

4) Use a remote grounding point and reduce the ground loop area. Let's take action to solve the problem!

Q: What factors cause the power supply to become hot？

A: 1) The power dissipation of linear power modules is relatively high due to their circuit structure, resulting in more internal losses for the same output power.

2) Overloading the module beyond its specified range in the data sheet can cause critical components to overheat.

3) High environmental temperatures or poor heat dissipation can also contribute to increased temperatures.

4) There may also be other sources of heat transfer, such as large heat-generating devices.

5)Overall, there are several factors that may contribute to elevated temperature in a linear power module, but with proper attention to specifications and environmental conditions, these modules can operate reliably and efficiently.

Q: How to reduce the temperature of the power supply during operation？

A: Solution:

1)When using a linear power supply, add a heat sink or choose a high-efficiency switch power supply;

2)Replace the module with a higher output power to ensure a 70% to 80% load reduction;

3) Lower the ambient temperature and maintain good heat dissipation. Let's focus on proactive and practical solutions to ensure optimal performance.

Q: What other applications power supply have in life？

A: There are many things to consider when using a switch power supply, and only by taking all the above into account can we avoid situations where it cannot be used properly. Switch power supplies are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instruments, medical equipment, semiconductor cooling and heating, air purifiers, electronic refrigerators, LCD displays, LED lamps, communication equipment, audio-visual products, security monitoring, LED lamp bags, computer chassis, digital products, and instrument fields.
