  • IP54 protection degree for indoor and outdoor installation

Antares stabilizers 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.

An automatic circuit breaker is provided 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 digital multimetre installed on the cabinet front panel. The alarms (min/max output voltage, gearmotor lock, internal overheating, regulator overload) are recognizable by means of LEDs on the control card.

The control logic is based on a digital microprocessor.

All Antares stabilizers are fitted with the same control card, thus simplifying maintenance operations and spare parts storage.
