Power Meter & Monitoring Relay

EMR-100

Power Meter & Monitoring Relay

The EMR-100 relay has been designed for the continuous monitoring of electrical parameters in medium or low-voltage 1-phase or 3-phase systems. It allows direct or remote monitoring of the system’s general conditions.

Some available versions of the EMR-100, can also be used to control the production process thanks to the programmable contacts suitable for various applications.
