Voltage Stabilizers

Field of application:

All those applications that need a constant supply without harmonic distortion. For 230V single-phase or 400W three-phase nets. Power up to 250 kVA single-phase and 750 kVA three-phase. Output voltage precision depending on customer request. IP-00 or IP-23.

Description and operation:

Our voltage stabilizers are composed basically by:

• An electronic voltmetric comparator that controls permanently the exit voltage and gives information when this is different from the nominal value.

• A changeable autotransformer of continuous regulation driven by a servomotor that receives the orders fromthe electronic comparator and supplies the necessary voltage to correct the deviation.

• A sum - subtraction transformer which primary is fed by the changeable autotransformer, being situated the secondary in series with the line.

• Optionally an isolation transformer is supplied to electrically isolate the net from the equipments in service.
