LED display SMPS 5V 40A 200W LED display transformer 5V power supply
1. What is switching mode power supply(SMPS)?
Switching power supply is a power supply that utilizes electronic switching devices (such as transistor, FET, SCR thyristor etc.)to control the time ratio of turn-on and turn off of switching tube and the electronic switching device modulates the input voltage by pulse,and achieve the DC/AC, DC/DC voltage conversion, and maintain stable output voltage.
2. What is advantage of Ruixiang power supply?
Small size, light weight, small power consumption and high efficiency, many types for selection which are widly used in telecommunications, CATV, digital products, audio, instrument, instrument, electric machinery, medical electronics, security, LED display, landscape and lighting system, etc.
