China's wholesale power supplies for LEDs use high-frequency DC/AC conversion technology to invert low-voltage DC into high-frequency low-voltage AC. After being boosted by a high-frequency transformer, the AC is rectified by a high-frequency rectification and filtering circuit into high-voltage DC, typically above 300V. Finally, it is converted into 220V mains frequency AC through a mains frequency inverter circuit for use by the load.
China's wholesale power supplies for LEDs are widely used in various fields such as household, automotive, communication, medical, scientific research, industry, transportation, and new energy.
Advantages and disadvantages of China's wholesale power supplies for LEDs:
China's wholesale power supplies for LEDs utilize high-frequency magnetic core materials that are small in size and lightweight, significantly enhancing the power density of the circuit. This results in minimal no-load losses in the inverter, thereby improving inverter efficiency. Typically, these power supplies achieve a peak conversion efficiency of over 90%. However, they also have notable drawbacks: they cannot handle fully loaded inductive loads and exhibit poor overload capacity.
Features of China's wholesale LED power supplies:
1. Wide input voltage range, high voltage regulation accuracy, and strong environmental adaptability.
2. Adopt microprocessor-controlled digital technology.
3. Pure sine wave output, with excellent electrical performance indicators.
4. With LED and LCD display, the user-friendly interface is intuitive and convenient, allowing real-time display of the inverter's working status, load status, environmental status, and parameters.
5. Choose either bypass priority or inverter priority.
6. Input and output electrical isolation, capable of withstanding the surge impact of computer load startup.
7. High-efficiency inverter, low no-load loss.
8. Advanced manufacturing technology ensures that the product is elegant and aesthetically pleasing.
9. It features input overvoltage protection, undervoltage protection, and reverse connection protection; output overload protection and short circuit protection; as well as mains bypass high voltage protection and low voltage protection.
10. In the absence of direct current (DC), it can be powered on and started using alternating current (AC).
