R-K Electronics, Inc. Protection Relays & Systems SVM-120A-79

The SVM-79 is a single-phase voltage relay for monitoring AC voltage and controlling a 10-amp dry contact output. It has a plug-in, 8-pin octal package and measures 3.1 in x 2.3 in x 1.8 in. For the 120VAC model, the undervoltage set point is adjustable from 90 to 110 VAC and the overvoltage set point from 112 to 140 VAC, with a fixed 0.5-second delay and 2% hysteresis. The relay operates at 0°C to 40°C, consumes 1.5 VA, and includes an indicating LED. Output ratings are 10 A at 250 VAC, 1/2 HP at 250 VAC, 1/3 HP at 125 VAC, and 10 A at 30 VDC. It is listed to UL 508 and features separate adjustable over- and undervoltage settings.
