R-K Electronics, Inc. Protection Relays & Systems LVM-1-75M-S

The LVM series is a low-voltage monitor AC/DC shunt relay designed for continuous monitoring of AC or DC voltage inputs from 5mV to 150V, with an internal relay that de-energizes when the sensed voltage exceeds the setpoint. It operates on 120 or 240 VAC, 50/60 Hz supply, with a maximum continuous sense voltage of 200V for 5-75mV ranges and 600V for all others. The relay has a 10A contact rating at 125VAC and 5A at 250VAC, with a 1600VA maximum resistive load. Mounting is surface mount via #6 screw, with terminal block termination and an open circuit board package. Operating temperature ranges from 0°C to 40°C, with storage from -40°C to 85°C. A 0.75-second decreasing voltage delay is standard. Hysteresis is 4% for AC input and 0% for DC. Power consumption is 3W.
