DTFPM fire protection equipment power monitoring module

The DTFPM firefighting equipment power supply monitoring voltage and current sensor module independently developed and produced by our company is used in conjunction with the DTFP firefighting equipment power supply monitoring equipment produced by our company. It uses RS485 communication, DTFPM voltage and current sensor, with main power supply voltage, backup power supply voltage and current And residual current measurement function, mainly used in the power monitoring system of fire-fighting equipment. This sensor has RS-485 communication interface, adopts Modbus-RTU protocol, and can be connected with the power supply status monitor of fire fighting equipment to form a power monitoring system for fire fighting equipment. It can effectively monitor the working power of fire-fighting equipment and avoid the situation that fire-fighting equipment cannot work normally due to power failure.
