R-K Electronics, Inc. Protection Relays & Systems LVM-2-4.5V-S

The LVM series is a low voltage monitor with AC/DC shunt relay functionality, designed to detect voltage levels and control output contacts based on sensed input. It mounts on a surface using a #6 screw and features a terminal block for connections, with an open circuit board packaging and a weight of 6 oz. It operates from 0°C to 40°C and stores from -40°C to 85°C. The device accepts 120 or 240 VAC supply at 50/60 Hz. The 4.5V sense range monitors 250 mV to 4.5 V AC/DC with 4% hysteresis for AC and 0% for DC. Output contacts are rated at 10 A at 125 VAC and 5 A at 250 VAC, with a maximum resistive load of 1600 VA. Input voltages up to 600 V are tolerated without damage. Signal impedance is 20 kΩ minimum. The decreasing voltage delay is 0.75 seconds typical. Power consumption is 3 W.
