The Model 2962 Voltage/Frequency Monitor is designed to monitor frequency, phase sequence and voltage. Before the relay will energize, phase sequence must be correct (A B C). Both the frequency and voltage must also be above the pickup setting before the relay will energize. If reverse phasing occurs, or if the frequency or voltage drop below the drop out setting, the relay will de-energize. Four red LED\\\'s are used to indicate whether the voltage or frequency are above or below their set points. A green LED indicates the condition of relay.

This device is powered by an external 24VDC supply. A typical application is to monitor engine-powered generators.
