Description
3 Phase Voltage Monitor Relay (SPVR2)
Normal Input Voltage: 120 VAC, 208 VAC, 480 VAC, and 575 VAC Phase to Phase
Frequency: 60 Hz
Ambient Temperature Range: 0-40 Deg C
Storage Temperature: -40 Deg C to + 85 Deg C
Weight: 2.5 lbs
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.
Features 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.
