Indusrial Low Power Consumption Electronic Filters

Traditional reactive power compensation equipments with electromechanical contractors, have a well proven performance in installation where the load has, slow variations and it is not very sensitive to voltage fluctuation. Today, however, more and more industrial installations, include electronic equipments that are very sensitive to voltage variations (PLC, computers, etc.) and also have very fast changing working cycles (automatic welding machines, robots, etc. ).

Reactive power compensation with static contractors(Thyristor switch) offers the best answer to these new industry requirements.

AB LIFASA Automatic capacitor banks with static contractors, use thyristors instead of traditional contractors. The thyristors switch-on capacitors on zero crossing voltage, and switch them off on zero current situation. The firing strategy grants a totally transient free switching of power capacitors, avoiding any problems with transient over voltages.
