The board is a DC power supply, do not directly input AC to AC transformer, plug-in a bridge rectifier and a filter capacitor can be. Also DC power not more than 50V, don&39;t lower than 20V, below 20V will not start. Also the output power and the power relationship, 50V will than 20V high power four times more.
