Orion - Y : Three-Phase independent control
<Back

The ORION Y three-phase stabiliser covers the power rating range between 5kVA and 230kVA and
allows for the choice of several input voltage variation percentages within a broad range (from +30%
up to -45%). For ±15%; ±20% and ±25%; ±30% range, the change of stabilisation is obtained
through different internal connections.

The regulation in the ORION Y stabilisers is independent on each phase. These stabilisers are
used with three-phase loads and single-phase loads with 100% unbalance with unbalance input
rated voltage and are suitable even in case of non-symmetric mains. In this configuration, the
voltage stabiliser requires the neutral wire presence
. It can also operate without neutral wire by
adding a proper equipment (?/zn0 or ?/Y isolating transformer or neutral inductance).

Every stabiliser belonging to this range is equipped with the same control board that can be found
on VEGA and ANTARES models. Stabilisers up to 45kVA are equipped with wheels to ease their
moving. Automatic circuit breakers are provided on the regulation circuit to protect against overload
and short circuit on the voltage regulator. The auxiliary circuit is protected by fuses.

The measuring instrumentation for the ORION Y stabilisers is installed on the cabinet door and
consists of one multi-task digital network analyser. Such instrument is able to provide with
information regarding the status of the line downstream the voltage stabiliser, such as phase and
linked voltages, current, power factor, active power, apparent power, reactive power, etc.

By means of a changeover contact, the stabiliser control card allows for the acoustic signalling of the following alarms: minimum voltage, maximum voltage, internal overheating and overload on the voltage regulator.
The control and the stabilisation of the voltage, performed on the true RMS value, are based on the microprocessor.
