R-K Electronics, Inc. Protection Relays & Systems LVM-1-400M-S-5000

The LVM series is a low-voltage monitor with an AC/DC shunt relay for continuous voltage sensing. It mounts on a surface via #6 screw, uses a terminal block, weighs 6 oz, and operates on 120 or 240 VAC, 50/60 Hz. The part senses 5-75 mV, 25-400 mV, 250 mV-4.5 V, 1.4-26 V, or 10-150 V AC/DC, with a maximum sense voltage of 600 V. Output contacts are rated 10 A at 125 VAC, 5 A at 250 VAC, or 1600 VA resistive. It has 4% AC hysteresis, a 0.75-second decreasing voltage delay, and operates from 0°C to 40°C with storage from -40°C to 85°C. Power consumption is 3 W. The LVM-1-400M-S variant senses 25-400 mV with a standard 0.75-second delay.
