AC Stabilisers are Special Types of AC Line Conditioners and are used where AC Voltage Levels must remain stable inside a defined tight AC voltage band.

AC Power Optimizers are more advanced form of AC Power Stabiliser.


1PH and 3PH electrodynamic voltage stabilisers rated from 1 to 8000 kVA

Ministab and Sterostab are registered names of two series of voltage stabilizers that offer a reliable and tested economic solution to inconveniences caused by voltage fluctuations. The use of voltage stabilizers increases the level of power quality and represents a real investment because the elimination of the inconveniences means a reduction in costs and an increase in productivity.

Very often it is only necessary to avoid a few minutes machine downtime or just one failure to repay the cost of the voltage stabilizers.
