12V/24V 40A PWM Controller : SC-2440 Controller

SC24V40A PWM Controller

The ROC-SOLID 12 Volt/24 Volt 40 Amp PWM Controller is an affordable entry level product which uses a microprocessor to provide SOC (State Of Charge) management functions, This in turn controls the charge current using PWM Technology and controls the supply of power to the load(s) according to the voltage and capacity of the battery.
