12v solar charge controller，solar  controller，pwm controller
Charge Controller Solar 50a is suitable for all types of solar panels, various types of batteries, MCU (micro-controller) with a PWM (Pulse Width Modulation) 0 ~ 100% variable duty cycle process. To provide fast, optimum charging voltage and current according to the actual charging situation and the type of battery.Charge Controller Solar 50a can show Real-time display (LED lights) battery capacity on the big display .Charge Controller Solar 50a charging is Safe, reliable and efficient.
Features OF ST7:

This type of controller is commonly used in applications such as motor speed control, LED dimming, and power inverters.

PWM controllers work by varying the duty cycle, which is the proportion of the on-time to the regular interval or period of time. A higher duty cycle increases the amount of power delivered to the device, while a lower duty cycle decreases it.
