Overview

3-phase voltage controllers which monitor :

- Undervoltage, adjustable from -20 to -2 % of Un

- Overvoltage, adjustable from 2 to 20 % of Un

- Presence of the neutral (H3USN only)

Measurements are taken between Phases for the H3US -

M3US and between Phases and Neutral for the H3USN

Faults are signalled via LEDs, distinguishing the origin of the fault (one LED for the upper threshold, one LED for the lower threshold).

Voltage selector switch : Set the selector switch to the 3-phase network voltage Un.

The position of this selector switch is only taken into account when the unit is powered up.

If the switch position changes while the unit is operating, all the LEDs flash but the product continues to work normally with the voltage selected on energisation prior to the change of position.

The LEDs return to their normal state if the switch is reset to its initial position defined before the last energisation.

- Undervoltage, adjustable from -20 to -2 % of Un (-12 to -2 % over the 3 x 208 V AC range and -17 % to -2 % for the 3 x 220 V AC range due to the minimum voltage 183 V AC)

An adjustable time delay from 0.3 to 30s can be used to disable the output relay during a transient fault.

In the event of a voltage fault, the relay opens at the end of the time delay set by the user.

In the event of phase failure, the relay opens instantaneously, without waiting for the end of the time delay.

When the unit is powered up with a measured fault, the relay stays open.
