With the development of society and the advancement of science and technology, energy conservation and environmental protection requirements are getting higher and higher. There is also an increasing demand for LED power supplies, and HVDC with high lifetime and reliability will replace the application of traditional UPS.
The main advantages of HVDC-powered LED lighting systems:
1. High efficiency. The traditional drive power efficiency is about 90%, and the HVDC rectifier module efficiency is greater than 95%. HVDC monitoring is used to implement the sleep function of the N+X redundancy module, which can ensure high efficiency under various load conditions.
2, easy to maintain. The HVDC power supply system is generally placed on the road surface. It does not need to be climbed up for maintenance. The HVDC power supply module has a hot-swap function, which can replace the faulty module under uninterrupted power.
3. Low cost. At present, the power supply can reach a life of more than 20,000 hours. The average price is 2.5-3 yuan/W, and the HVDC power supply can greatly reduce the cost. When the power supply reaches 15KW or more, 1.5-2 yuan/W can be realized. When the number of lamps is relatively large, the use of HVDC power supply can reduce the cost of the entire system.
