Description
Each phase is regulated independently, so the voltage imbalance between phases, typical of overloaded rural networks, is levelled separately on each circuit. For single-phase consumers connected to different phases, this means that a sag on one phase does not affect the others. The SVS3x35 and SVS3x75 models accept an input from −26 to +18 % of nominal and keep the output within ±6 %. The SVS3x45 is set up differently: it works at ±20 % on the input and stabilizes more accurately, with a tolerance of ±3 %. The units are built in a floor-standing metal cabinet with digital indicators on the door.
How to choose
Choose the model by the highest phase current of the load, taking compressor starting currents into account. When output accuracy matters, for example for IT equipment, it is better to take the SVS3x45 with ±3 %. Above 54 kVA there is nothing in this line; next look at the AVR-L (AVR3LS) at 70–140 kVA with 3 % accuracy or the thyristor AVR3AS / AVR3AE / AVR3AN up to 2 MVA.

FAQ
What power do the SVS3x35, SVS3x45 and SVS3x75 stabilizers have?
The rated current is 35, 45 and 75 A per phase, which corresponds to the 25–54 kVA range for a three-phase network.
How does the SVS3x45 differ from the SVS3x35 and SVS3x75?
The SVS3x45 works with an input deviation of ±20 % and holds the output with ±3 % accuracy. The other two models accept −26 to +18 % and stabilize with ±6 % accuracy.
Does the SVS three-phase stabilizer regulate each phase separately?
Yes, control and regulation are done for each phase separately. This is useful when single-phase loads are unevenly distributed between phases.
Which three-phase stabilizer to take if more than 54 kVA is needed?
The next step is the AVR-L (AVR3LS) at 70–140 kVA with an input range of ±20 %, and for large sites the AVR3AS / AVR3AE / AVR3AN series up to 2 MVA.
