AC voltage stabilizer
Eremu
Field of application:
All those applications that need a constant supply without harmonic distorsion. 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 from the 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.
