Electromagnetic Industries 3 Phase Voltage Monitor SPVR 575

Electromagnetic Industries 3 Phase Voltage Monitor SPVR 575/SPVR2-575 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 UnderVoltage 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 voltageafter being in Under-Voltage alarm conditions for more than 1 sec. Normal Input Voltage: 575 VAC Phase to Phase Operating Voltage Range: 460-661 Frequency: 60Hz Ambient Temperature Range: 0-40 Deg C. Storage Temperature: -40 Deg. C to + 85 Deg. C Weight: 2.5 Standard Features Power On Indication (LED) “Form C” contacts Phase Reversal Protection with LED indication Phase Unbalance Protection (2% to 8% Adjustable) withLED indication Phase Loss Protection with LED indication Under voltage Protection (80%) with LED indication Over Voltage Protection (115%) with LED indication Adjustable Trip Time Delay (0 to 30 Sec.) Adjustable Reset Time Delay (except for the 120V) (1 Secto 5 min.) Automatic Reset when condition clears and at Power Up Panel or Door Mounting Options Clear Cover Maintain Fault indication after Loss of Power.
