Operation
Nominal Voltage Monitor
The SVM-A6857 monitors single phase AC voltage and operates a dry set of contacts. When the voltage being monitored is between the independently adjustable upper and lower set points, the output relay and indicating LED are energized. If the voltage goes higher than the overvoltage set point or lower than the undervoltage set point, the output relay will be de-energized and the LED will go out. A time delay avoids the effects of quick variations in the voltage.
