MD0630STA-PM Introduction

The MD0630STA-PM AC DC leakage current sensor(compatible with Type A and Type B) features high sensitivity, accurate measurement, and a compact & integrated design. It outputs an alarm signal when it detects a DC leakage current of 3-6mA or an AC leakage current of 15-30mA. It also has a self-test function. Its outstanding features are its ultra-small size and ultra-low price(Type B Quality, Type A Price).


This series of products has important applications in various fields, including industrial equipment, medical instruments, new energy, and smart cities. It is particularly suitable for charging electric vehicles, electric motorcycles, and electric bicycles in various public places. It is simple to use and install.
