CM-EFS Voltage Window Monitoring Relay - Single Phase AC/DC


The voltage window monitoring relay CM-EFS.2 can be used for the simultaneous monitoring of over- (>U) and undervoltages (

The voltage to be monitored (measured value) is applied to terminals B-C. Open- or closed-circuit principle as well as an adjustable ON A or OFF tripping delay are configurable.

Monitoring of DC- and AC voltages from 3-600 V
RMS measuring principle
One device includes 4 measuring ranges: 3-30V; 6-60V; 30-300V; 60-600V
Over- and undervoltage monitoring
ON-or OFF-delay configurable
Open- or closed circuit principle configurable
Latching function configurable
Thresholds for Umin and Umax adjustable
Fixed hysteresis of 5%
Tripping delay TV adjustable 0; 0.1-30s
1x2 c/o contacts (common signal) or 2x1 c/o contact (separate signals for Umin and Umax)
22.5mm width
