Features EASY TESTING Besides, the power converter with digital display can also test the positive voltage and positive current, useful and reliable. The protection: when the output voltage is less than 0.8V, there is a low voltage protection LVP. If the output current is greater than 2A, there is an overcurrent protection OcP. In case of overload, there is an overload protection OPP that automatically switches off the output. The LCD backlight flashes and shows the appropriate protection. Voltage Converter The step-down and step up converter can convert DC 5V to DC 3.3V, 9V, 12V, 24V, giving you a stable power supply. Adjustable Use In addition, the converter module used an adjustable multi-turn potentiometer to regulate the voltage with higher accuracy. Easy to Install Comes with a light weight and compact size, the convenient installation can be completed quickly in minutes.
