AMC72L-AI Single Phase Programmable AC Ammeter

AMC series meters adopt AC sampling technology, which can measure the current, voltage, power, power factor and electric energy parameters in the power grid separately. It can adjust the magnification through the panel membrane switch. The meters have an RS485 communication interface with Modbus protocol and can convert the current signal into a standard DC analog signal.

  • Single-phase current meter
  • LCD display
  • RS485 and Modbus RTU protocols
  • Input AC 1A or 5A
