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

The LVM series is a low voltage monitor designed as an AC/DC shunt relay for monitoring voltage levels with a 120 or 240 VAC, 50/60 Hz supply. It mounts via surface mounting with #6 screws and uses a terminal block for termination. The LVM-1-150V-F variant senses 10V to 150V AC/DC with a 0.10 second increasing voltage delay, and has a 10 Amp contact rating at 125VAC and 5 Amp at 250VAC, supporting up to 1600VA resistive load. It operates from 0°C to 40°C and stores from -40°C to 85°C, with a 4% hysteresis for AC input. Signal impedance is 20kΩ minimum, and maximum sense voltage is 600V for all ranges except 5-75mV, which is limited to 200V. The device consumes 3W and features noise filtering and nuisance delay.
