R-K Electronics, Inc. Protection Relays & Systems LVPR-1-26V-L

The LVM series is a low-voltage monitor with AC/DC shunt relay functionality, designed to sense voltage levels and control an output relay based on preset thresholds. It mounts on a surface using #6 screws and features a terminal block for connections on an open circuit board, weighing 6 oz. The LVPR-1-26V-L variant senses DC or AC voltages from 1.4V to 26V with a 0.75-second decreasing voltage delay, operates with a 120VAC supply, and has a 10A contact rating at 125VAC or 5A at 250VAC. Ambient operating temperature ranges from 0°C to 40°C, with storage from -40°C to 85°C. The input signal impedance is 20kΩ minimum, and the device handles up to 600VAC on sense inputs without damage. Hysteresis is 4% for AC input and 0% for DC, with noise filtering and nuisance delay features. A 3W power consumption is specified.
