R-K Electronics, Inc. Protection Relays & Systems SVM-240A-10

The SVM series is a single-phase voltage relay designed to monitor AC or DC voltage and operate dry contacts for over and under voltage conditions. It features a plug-in mounting style with an 8-pin octal termination and a dust cover. The relay has a fixed 0.5-second delay, 2% hysteresis, and operates within an ambient temperature range of 0°C to 40°C. For the SVM-240A variant, the nominal voltage range is 200 to 250VAC with a contact rating of 10 amps at 30VDC. The unit consumes 1.5VA and weighs 9 oz. The LED indicates normal operating conditions. The model supports adjustable over/under voltage thresholds of ±10%, ±13%, or ±16% of nominal voltage.
