Model EI-SPVR2 Relay
Application: The EI-SPVR2 is designed to monitor Phase to Phase voltage for three Phase electrical equipment that are sensitive to Phase Loss, Phase Unbalance, Phase Reversal, Over-Voltage, and Under-Voltage conditions.
The SPVR2 has a set of “Form C” contacts that change state if an abnormal condition exists for the duration of the adjustable time delay. The exception is that the unit will trip instantaneously ant time it detects a Phase Reversal or the Over-Voltage reaches 150% of rated voltage, or the voltage drops below 50% rated voltage after being in Under-Voltage alarm conditions for more than 1 sec.
