Datasheet

The under or overvoltage threshold value is set by a graduated potentiometer by reading the Un scale to be monitored directly.
The hysteresis is set by a graduated potentiometer from 5 to 20% of the preset threshold. The hysteresis value cannot be higher than the extremes of the measurement range.
In overvoltage mode, if the controlled voltage exceeds the preset threshold for longer than the time set on the front face (0.1 to 10 s), the output relay opens and LED R is extinguished. During the
time delay, this LED flashes.
Once the voltage falls below the threshold value minus the hysteresis, the relay closes instantaneously.
In undervoltage mode, if the controlled voltage falls below the preset threshold for longer than the time set on the front face (0.1 to 10 s), the output relay opens and LED R is extinguished. During
the time delay, this LED flashes.
Once the voltage rises above the threshold value plus the hysteresis, the relay closes instantaneously.
