Product Description

The HGR41EW series are part of the easywire ^® family of meters. The easywire ^® system has been designed to save up to 90% installation time compared to a standard meter and current transformer installation.

This MID approved DIN rail mounted multifunction energy meters is suitable for monitoring energy consumption and many other electrical parameters in industrial and commercial applications. These meters may be used in three phase applications and have been certified for billing purposes.

A high efficiency white backlit LCD display provides clear indication of measured values in all light conditions.

Push-buttons on the front of the meter allow the user access to the display page required.

The meter is available in two versions:-

- With single pulse output and RS485 Modbus communication

- With single pulse output and Mbus communication

The unit is housed in a compact four module width housing suitable for DIN rail mounting.
