ZK-SJ4 60W Voltage Stepper - Booster Module Solar Charging Circuit
ZK-SJ4 is an adjustable voltage stepper - booster circuit. It allows you to convert DC voltage between 4-30V to the desired DC value between 0.5-30V. You can also charge your products such as batteries or accumulators with the solar panels you connect to the input of this product.
You can adjust both voltage and current with the two trimpots on the product. While the CC trimpot is used to adjust the current, the CV trimpot is used to adjust the output voltage.
The charging status can be checked thanks to the 3 LEDs on the product.
CH: Charging LED
FL: Full charge LED
CC: Constant Current LED
