Voltage Stabilizers

If you have an issue with your Power Quality,

The voltage stabilizer is the solution with the best cost / benefit ratio and has proven to be very effective in preventing potentially dangerous situations caused by the instability of the input voltage. A voltage stabilizer is a power device positioned between the mains and the load. The purpose is to ensure a voltage subject to a variation much lower then the one guaranteed by the distributing system.

We are located in Northern Germany and offer high grade Voltage Stabilizers, Transfomers, Power Factor Correction units and Generators. „High Grade“ is not just a word for us, we give you up to a 5 year warranty and offer worldwide support!

Voltage Stabilizer Operation

Our voltage stabilizers are designed to operate with a rated voltage in accordance with the International Norm IEC 60038 and are to be connected between main power supply and load.

The purpose is to supply the loads with a stabilised voltage having an input voltage variable in relation to the rated value. The highest input current is obtained with the minimum rated voltage; as the output voltage is stabilised within a close range (±0.5%), it can be considered constant.

Stabilization takes place on the ‘TRMS’ value of the voltage and is not affected by harmonic distortion in the mains.


Load Variation

Our voltage stabilizers can operate with a load variation range from 0 to 100% on each phase, the response time depends on the input voltage percentage variation and on the type of design (indicatively, it can vary between 12,5V/sec and 1300V/sec).

The voltage stabilizers are not affected by the load power factor and since regulation is performed without chopping the voltage sine wave, neither an appreciable harmonic distortion nor a phase displacement are introduced on the downstream line.



The voltage stabilizers are housed in a metal enclosure with RAL 7035 finish and IP21 protection class, suitably sized according to power rating. Depending on the model, the stabilizers are cooled by air (natural or aided convection).
