Product Details

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
