R-K Electronics, Inc. Protection Relays & Systems LVM-1-4.5V-L

The LVM-1-4.5V-L is a low voltage monitor AC/DC shunt relay designed for voltage sensing in control applications. It mounts on a surface using a #6 screw and uses a terminal block for connections. The relay operates with a 120 or 240 VAC supply and senses input voltages from 250 mV to 4.5 V AC/DC. It features a 10 A contact rating at 125 VAC and a 5 A rating at 250 VAC, with a maximum resistive load of 1600 VA. The output relay is energized by default and de-energizes when the sensed voltage exceeds the set point, with a decreasing voltage delay of 1.50 seconds. The operating ambient temperature range is 0°C to 40°C, with storage from -40°C to 85°C. The unit weighs 6 oz and has dimensions of 3.875 in x 2.625 in x 1.5 in. The device includes noise filtering and hysteresis to prevent relay cycling.
