single-phase stabiliser covers the power rating range between 35kVA and
135kVA 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.
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.
A buzzer is activated whenever an overload condition occurs.
instrumentation for the ANTARES stabilisers is installed on the cabinet
door and consists of a multimeter and an ammeter. Such instrument is
able to provide with information regarding the status of the line
downstream the voltage stabiliser, such as phase voltage, current, power
factor, cosj, 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 logic control is based on a digital microprocessor.
