R-K Electronics, Inc. Protection Relays & Systems LVM-1-150V-S

The LVM-1-150V-S is a low voltage monitor AC/DC shunt relay designed for voltage sensing and protection in control applications. It operates from 120 VAC supply voltage and senses input voltages from 10V to 150V AC/DC with a 4% hysteresis for AC input. The relay has a 10A contact rating at 125VAC and 5A at 250VAC, with a maximum resistive load of 1600VA. It includes a 0.75-second decreasing voltage delay and a noise filter to prevent nuisance operation. The device is mounted on a surface using #6 screws, has terminal block termination, and weighs 6 oz. Ambient operating temperature ranges from 0°C to 40°C, with storage from -40°C to 85°C. Maximum continuous sense voltage is 600V for all ranges except 5-75mV, which is limited to 200V. Signal impedance is 20kΩ minimum, and frequency response is DC to 400Hz.
