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

LVM-1-75M-F is a low voltage monitor AC/DC shunt relay designed for continuous operation with 120 or 240 VAC supply voltage. It senses input voltages from 5 to 75 mV AC/DC and features a 10 A contact rating at 125 VAC, with a 0.10 second increasing voltage delay. The device mounts on a surface using a #6 screw, weighs 6 oz, and operates within a temperature range of 0°C to 40°C with storage from -40°C to 85°C. It has a 20 kΩ minimum input impedance, 4% hysteresis for AC input, and accepts up to 600 VAC on the sensing input without damage. Power consumption is 3 W, and it includes noise filtering and nuisance delay to prevent relay cycling.
