Commander He Jian and his delegation from the Military District of Xiangtan City conducted research

The power supply adopts a wide voltage input switching power supply, while the intrinsic safety part adopts advanced overvoltage protection and regulation devices for current and voltage detection. High power, low internal resistance MOSFETs are used for overvoltage output protection. The intrinsic safety module for dual current, voltage detection, and relay output protection outputs an intrinsic safety DC power supply. It has the characteristics of wide input voltage range, high power, stable output, and reliable safety performance. Mainly suitable for supplying power to intrinsically safe equipment in hazardous environments with explosive gases such as gas and coal dust underground in coal mines.
