Renogy 30 Amp PWM Charge Controller Regulator Off Grid for Battery Charging

Renogy 30 Amp PWM Charge Controller Regulator Off Grid for Battery Charging

Description The main advantage of Pulse Width Modulation (PWM) is that power loss in the switching devices is very low. When a switch is off, there is practically no current. When the device is on, there is almost no voltage drop across the switch. Power loss, being the product of voltage and current, is thus in both cases close to zero. PWM also works well with digital controls, which, because of their on/off nature, can easily set to the needed duty cycle. This solar system controller adopts
