Orion Plus stabilizers are available for different ranges of input voltage fluctuation. In the ±15%/ ±20% and ±25%/ ±30% types, the change of input range is obtained through different internal connections.

The Orion Plus voltage stabilizers regulate the output voltage independently on each phase.

Similarly to the Orion stabilizers, they can supply any single-phase, bi-phase and three-phase load even in case of and up to 100% unbalanced load current and asymmetrical mains distribution.

In this configuration, the presence of the neutral wire is required. The stabilizer can also operate without neutral wire by adding a device able to generate it (D/zn or D /yn isolating transformer or neutral point reactor).

The stabilizers are cooled via natural air ventilation, assisted by extracting fans when the cabinet internal temperature exceeds 35°C).

The instrumentation consists of two multi-task digital line analysers which are able to provide with information regarding the status of the lines upstream and downstream the voltage stabilizer (phase and linked voltages, current, power factor, active power, apparent power, reactive power, etc.)

The operating status of the stabilizer can be monitored by means of the LEDs on the front panel displaying all the information regarding each phase operating mode (‘power on’; reaching of voltage regulation limits; increase/decrease of voltage regulation) and the possible alarms (minimum and maximum voltage, maximum current: overtemperature; ventilation failure). The alarm indicators are accompanied by an acoustic alarm.

  • Up to 250kVA ±15%, the regulation circuit is protected against overload and short circuit on the voltage regulator by an automatic circuit breaker.
  • – From 300kVA ±15%, an electronic voltage regulator protection system activates in case of overload on the voltage regulator. In such condition, the load supply is not interrupted, but the stabilizer output voltage is automatically set to the lower between the mains voltage and the pre-set output voltage. The service continuity is guaranteed, although the voltage is not stabilised. When the overload condition ceases to exist, the stabilizer switches automatically back to regular functioning.

The auxiliary circuits are protected by fuses.

The control logic, performed on the true RMS value, is based on DSP microprocessors.

The unit parameters and the output voltage reference can be set by using a personal computer, thus allowing for dealing directly in the field with any problems related to voltage stability.

All Orion Plus stabilizers are provided with Class II SPD surge arrestors.
