AMC72L-DI Single Phase Programmable DC Ammeter

AMC72L-DI is an intelligent meter designed for power supply monitoring of power systems, industrial and mining enterprises, public facilities and intelligent buildings. It can measure DC signals with RS485/MODBUS-RTU protocol; with switch input and relay output, it can realize the functions of "remote signaling" and "remote control" of circuit breaker. It has LCD display interface and allows parameter setting and control through panel buttons, which is very suitable for real-time power monitoring system. Acrel AMC series AC ammeter and voltmeter adopts AC sampling technology and can directly measure current and voltage of three-phase network. It can be used for local display and connection of industrial control equipment to form a measurement control system.
