Description
The contactless circuit is built on booster transformers switched by thyristors in phase or antiphase. Control is microprocessor-based with true RMS measurement, with an LCD interface and programmable protections. No maintenance is needed because the stabilizer has no mechanical parts. The output is 220/230/240 V single-phase and 380/400/415/420 V three-phase line, at 50 or 60 Hz. Accuracy depends on the model and lies within ±1.3…±4.3%, so for sensitive equipment it should be checked against the consumer's requirements. The built-in uninterrupted bypass allows taking the unit out for service without switching off the load. The basic version has protection degree IP20, from IP00 to IP65 with options, and the operating temperature is −5…+45 °C. Ratings above 400 kVA are made to order.
How to choose
The model is chosen by power and by the width of the input window. The R18–R90 series covers input deviations from ±9% to ±45.5%, and the output accuracy of ±1.3…±4.3% depends on the specific model. If a tighter ±0.1% is needed, compare with the TSP at 1–100 kVA. For small ratings and accuracy of ±0.32…±1.6%, look at the three-phase TS at 2.97–146 kVA. When the unit is installed outdoors, there is the TSO in an enclosure up to IP65 from 5 kVA.

FAQ
How does the solid-state SVR differ from a servo-driven stabilizer?
Regulation is done by thyristors switching booster transformers, with no moving parts. Response time is 20 ms, no maintenance is needed.
What power do single-phase and three-phase SVR units have?
Single-phase 5–50 kVA, three-phase 30–400 kVA, and above 400 kVA is made to order.
What input voltage range can the SVR handle?
From ±9% to ±45.5% depending on the model in the R18–R90 series.
Does the SVR have a bypass, and what is the protection degree?
The bypass is built-in and uninterrupted. The basic protection degree is IP20, from IP00 to IP65 with options.
What is the output voltage accuracy of the SVR?
From ±1.3 to ±4.3% depending on the model, efficiency at least 98%.
