LT Series PWM solar charge controller
LT Series PWM solar charge controller
regulate thevoltage and current of an electricpower supply to charge a battery. ltdoes this by using a microcontrollerto adiust the duty cycle of a PWM signal, which controls the averagevoltage applied to the battery. This allows the controller to maintain thebattery at a constant voltage andcurrent,ensurina safe ano efficientcharging. Other key features of PWM controller include overcharge protection, over-currentprotection, and temperature compensation which help to protect the battery and ensure longer battery life.
