Product Details From Manufacturer
The Single-Phase Under/Over Voltage Relay is a protective relay that is sensitive to both undervoltage and
overvoltage conditions in single-phase power systems. It trips when the voltage moves outside the set voltage
limits.
Voltage setpoint and hysteresis adjustments are provided for undervoltage and overvoltage. Two independent
sets of contacts are provided: one for undervoltage and one for overvoltage.
Specifications
Nominal Input Voltage - 69 Vac
Maximum Input Voltage - 120% of nominal input voltage
Undervoltage Setpoint Range - 75% to 100% of nominal input voltage
Overvoltage Setpoint Range - 100% to 125% of nominal input voltage
Hysteresis Range - 1% to 15% of nominal input voltage
Output Contacts - 2 x SPDT: 0.5 A at 120 Vdc; 5 A at 240V ac
