Potentiometer current output range

The minimum value:4000mA; maximum value: 9000mA; Remark: the total output power does not exceed 320W (actual output voltage * actual output current = power), otherwise, it can not be guaranteed.

Please use the matching programmer to set the output current 

Protection functions

Open circuit 

When the LED disconnection the product is protected such as hiccup or when it is at the highest point of output voltage, the power supply shall be self-recovery when the fault condition is removed.

Short Circuit 

The input power shall decrease when the output rail short, the power supply shall be

self-recovery when the fault condition is removed.
