PCB size is about 103*78mm
the assembeld board max height is about 32mm
Considering the voltage regulation performance and power consumption, it is recommended that the input AC be slightly larger than the required output DC.
For example, if you need +/-DC9V out, you can use dual AC10-12V
The long-term test conditions for our radiators are:
①Input AC12V, output DC12V, current 450mA.
②Input AC18V, output DC15V, current 200mA (if AC15V input is used, the load current can be larger)
The above two can be used as a reference. If you need a larger current, please add and modify the radiator by yourself.
