LED Display Power Supply
LED Display Power Supply
Introduction of led display power supply:
Three Function of led display power supply:
1. Overload protection: Power protection between 110 to 150% range of rated overload, when output hiccups, disconnect the power to reduce the load, and give power again to recover normal output.
2. Over voltage protection: power protection between 115 to 150% range of output voltage. Power inside will limit the max output voltage, disconnect power, after solve the problem, then can give power again.
3. Short circuit protection: when output short circuit, power protection.
Use environment of led display power supply:
Work environment temperature: -20℃～+50℃
Work humidity: 20~90%RH
