CM-ESS Voltage Monitoring Relay - Single Phase AC/DC


Depending on the configuration, the voltage monitoring relays CM-ESS.1 and CM-ESS.2 can be used for over- or undervoltage monitoring in single-phase AC and/or DC systems. The voltage to be monitored (measured value) is applied to terminals B-C. The devices work according the open-circuit principle.

If the measured value exceeds resp. drops below the adjusted threshold value, the output relay(s) energize(s): on the CM-ESS.1 immediately, on the CM-ESS.2 after the set tripping delay TV. If the measured value exceeds resp. drops below the threshold value plus resp. minus the adjusted hysteresis, the output relay(s) de-energize(s).

Monitoring of DC- and AC-voltages from 3-600V

RMS measuring principle

One device includes 4 measuring ranges: 3-30V, 6-60V, 30-300V, 60-600V

Over- and undervoltage monitoring configurable

Hysteresis adjustable from 3-30%

Tripping delay TV adjustable 0; 0.1-30s

3 supply voltage versions

2 c/o contacts

22.5mm width

3 LED's for status indication
