Electromagnetic Industries 3 Phase Voltage Monitor SPVR 240

Electromagnetic Industries 3 Phase Voltage Monitor SPVR 240 Application: The EI-SPVR2 is designed to monitor Phase to Phase voltage for three Phase electricalequipment that are sensitive to Phase Loss, Phase Unbalance, Phase Reversal, Over-Voltage, and UnderVoltage conditions.The SPVR2 has a set of “Form C” contacts that change state if an abnormal condition exists for the duration ofthe adjustable time delay. The exception is that the unit will trip instantaneously ant time it detects a PhaseReversal or the Over-Voltage reaches 150% of rated voltage, or the voltage drops below 50% rated voltageafter being in Under-Voltage alarm conditions for more than 1 sec. The SPVR2 240 does not detect Phase Unbalance
