Switching power input is marked with 220V AC, 36V output, but the actual input voltage is 238V, the output of the switching power supply affect it? Will it damage the switching power supply? Do not know the reason is not the voltage, power after a period of time (10 minutes), the switch power suddenly no output, and the display is not bright, switching power is not already broken? Guiqiu prawn to the doubts!
The actual input voltage at 238V, the output of the switching power supply has no effect, the general input voltage range of 10% or more;
"Power after a period of time (10 minutes or so), the switch power suddenly no output, and the display does not light," the switching power supply is already broken
Switching power supply without output, usually two problems, the first is the switching power supply is broken, the second is the switching power supply output overload, power overcurrent protection or overheating protection, the former need to repair, the latter to remove the load off 220V input Voltage after 5 minutes and then on the 220V to return to normal. The input voltage of 238V is also within the allowable range of the switching power supply, regardless of this.
238V on the open power supply no effect, the general AC85-265V;
What is the load on your switching power supply? Will it be the cause of the load? The indicator light does not shine is likely to switch the power supply is broken, or that is the input power is cut off,
