The SVM series is a single-phase voltage relay for monitoring AC or DC voltage, with plug-in mounting and an 8-pin octal termination. It features over and under voltage detection with ±10%, ±13%, or ±16% adjustable thresholds, a fixed 0.5-second delay to prevent nuisance tripping, and a 2% hysteresis. The relay includes dry contacts rated at 10 amps at 250VAC or 30VDC and has a power consumption of 1.5VA. Operating temperature ranges from 0°C to 40°C, with storage from -40°C to 85°C. The SVM-24D variant monitors 22 to 27VDC input. The unit weighs 9 oz and includes a dust cover. Its LED indicates normal operating conditions.
