R-K Electronics, Inc. Protection Relays & Systems SVM-120A-A6857

The SVM-120A-A6857 is a single-phase voltage monitor designed to detect over and under voltage conditions in both AC and DC systems. It operates with a nominal voltage range of 100 to 130VAC and features a single knob adjustment for setting the control voltage. The relay activates dry contacts rated for 10 Amps at 250VAC and 30VDC, with a fixed delay of 0.5 seconds to mitigate short-term voltage fluctuations. This device includes a nuisance delay feature and offers a drop-out range window of 0-10%, 1-13%, or 2-16% of the nominal voltage. The SVM-120A-A6857 is compact, weighing 9 ounces, and is suitable for ambient temperatures ranging from 0¬8C to 40¬8C during operation and -40¬8C to 85¬8C for storage. It is packaged with a dust cover and requires an 8-pin octal socket for connections.
