Product Details

Three-phase energy meter with removable front LCD display unit. The same unit can be used either as a DIN-rail mounting or a panel mounting energy meter. This general purpose Three-phase Energy meter is suitable for both Active and Reactive Energy metering for cost allocation but also for main electrical parameter measurement and re-transmission (transducer function). 

Housing for DIN-rail mounting with IP50 (front) protection degree. Current measurements carried out by means of external current transformers (0.333V) and voltage measurements carried out either by means of direct connection or by means of potential transformers. 

EM21-72V is provided, as standard, with a Pulsating output for Active energy re-transmission. In addition a 2-wire RS485 communication port is available as an option.

EM21 model types:

  1. Carlo Gavazzi EM21-72V Panel or DIN Rail Meter with Pulse Output (EM21-72VMV53XOXX)
  2. Carlo Gavazzi EM21-72V Panel or DIN Rail Meter with Pulse and Modbus output (EM21-72VMV53XOSX)
