AMC72L-AI3 can measure the current signal in the three-phase power grid in real time, the instrument can have RS-485 communication interface, adopt Modbus-RTU protocol; can have analog output, relay alarm output, switch input/output. According to different requirements, parameters such as transformation ratio, alarm and communication can be set and controlled through the buttons on the instrument panel.
AMC series AC ammeter&voltmeter, adopting AC sampling technology, can directly measure current and voltage of three phase grid. It can be used for local display, and connecting industrial control device to form measuring control system.
AC current: AC 1A, 5A
LCD display for three phase current measurement
