WHOOSH is a top 5 brand of LED Power supply in China after 20 years development since 2004.

WHOOSH power supply is equipped with advanced production equipment and a high-quality management team. The company has passed the IS09001:2015 quality management system, and the products have passed domestic and international certifications such as CCC, CE, and FCC, and won the title of National High-tech Enterprise.

The company employs over 400 individuals, including 50 R&D and engineering technicians. Millions of yuan were invested in acquiring advanced equipment from Germany and establishing an EMC laboratory to ensure the provision of stable and reliable design solutions and products to customers.

When choosing different LED power supplies, the decision should be based on the specific application scenarios and requirements.. Here are some key factors and suggestions:

1. Well-define Requirements: First, It is essential to determine the type of power supply required for the device., such as input and output type (AC/DC, DC/DC, DC/AC), input voltage specification (110V, 220V or universal input voltage), and the required output voltage and current. For example, if the load is 15V, 60mA, it is recommended to choose a power supply of more than 100mA.

2. Consider load characteristics: The switching power supply works best at 50%-80% load. If the load is a motor, bulb or capacitive load, it is necessary to consider that the instantaneous current at startup is large, and a suitable power supply should be selected to avoid overload.

3. Ambient temperature: Consider the working ambient temperature of the switching power supply, and whether there are additional auxiliary heat dissipation devices. The power supply needs to be derated at too high ambient temperatures. High temperature may reduce the performance of the power supply and capacitor; high humidity environment may affect the insulation performance of the equipment.

4. Select the topology: Select the appropriate topology, such as Buck, Boost, Buck/Boost, Flyback, Forward, etc., according to whether it is high power or low power, high voltage output or low voltage output, and whether the number of devices is as small as possible.

5. Size and weight: Select a switching power supply of appropriate size and weight according to space constraints. Light box power supplies generally have requirements for power supply size.

6. Power factor correction (PFC): Consider whether power factor correction is required to reduce the impact on the power grid.

7. Isolation and non-isolation: Select isolated and non-isolated switching power supplies according to safety requirements. Isolated power supply with higher safety standard commonly is used in industry, medical and communication equipment, cost also higher. Non-isolated power supply widely is used in LED signs and lightings.  

8. Protection function: Select a power supply with overvoltage protection (OVP), over-temperature protection (OTP), overload protection (OLP) and other protection functions.

9. Electromagnetic compatibility (EMC): Select a power supply that meets electromagnetic compatibility standards according to usage.

10. Application scenarios: Different application scenarios have different requirements for switching power supplies. For example, household appliances, communication equipment, industrial automation, medical equipment, and electric vehicles all have their own specific power requirements.

11. After-sales service: confirm the after-sales service provided by the seller to ensure that any problems that arise during use can be resolved.

12. Brand and quality: choose a well-known brand of switching power supply, the quality is more guaranteed.

Considering the above factors comprehensively, the switching power supply that best suits the application scenario can be selected. In addition, specific application scenarios and special requirements can also be referenced., such as whether isolation is required, whether it is suitable for high humidity environments, whether there are special safety standards, etc., to further determine the model and specifications of the switching power supply.
