Orion

Standard features

Orion stabilisers are available for different ranges of input voltage fluctuation.

Standard models offer a double input connection so that with the same unit two different input variations (±1 5%/±20% or ±25%/±30%) can be dealt with.

The output voltage regulation is performed independently on each phase (stabilization of each phase-to-neutral voltage).

Orion stabilisers are used with three-phase loads and single-phase loads with 100% current imbalance across the phases and asymmetrical mains voltage.

For the correct operation, Orion voltage stabilisers require the neutral wire presence. Operation without neutral wire connection is achievable by adding a device able to generate it (D/Yn isolating transformer or neutral point reactor).

An automatic circuit breaker is mounted on the regulation circuit to protect against overload and short circuit on the voltage regulator, whilst the auxiliary circuit is protected by fuses.

The instrumentation consists of a multi-task digital line analyser. Such instrument is able to provide with information regarding the voltage stabiliser output parametres, such as phase and linked voltage, current, power factor, active power, apparent power, reactive power, etc.

The alarms (min/max output voltage, gearmotor lock, internal overheating, regulator overload) are recognizable by means of LEDs on the control card.

Voltage control and stabilisation, performed on the true RMS value, are managed by the digital microprocessor. Each phase of every stabiliser belonging to this range is controlled by the same control board used on Vega and Antares models, thus simplifying maintenance operations and spare parts storage.

Up to 45kVA, the stabilisers are equipped with wheels for easy handling.

* The output voltage can be adjusted by choosing one of the indicated values.
Such choice sets the new nominal value as a reference for all the stabiliser parameters.
