Datasheet

In overvoltage mode, if the controlled voltage exceeds the preset threshold for longer than the time set on the front face (0.1 to 3 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 3 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.
If "with memory" mode has been selected, the relay opens and stays in this position when threshold crossing is detected.
The power supply must be disconnected to reset the product.
