Three-phase inverter voltage stabilizers Volter EtalonS 10.5–42 kW (3×4 … 3×14)
Country: Ukraine · Model: EtalonS-12 – EtalonS-42
EtalonS is a line of three-phase inverter stabilizers from 10.5 to 42 kW, each built from three single-phase modules, one per phase. Stepless regulation causes no light flicker or voltage jumps for sensitive electronics. The series fits small production sites, workshops, shops and sites with generators and solar plants.

Description
The line has six models, EtalonS-12 (3×4) at 10.5 kW and 16 A, EtalonS-16.5 (3×5.5) at 25 A, EtalonS-21 (3×7) at 32 A, EtalonS-27 (3×9) at 40 A, EtalonS-33 (3×11) at 50 A and EtalonS-42 (3×14) at 63 A. The input range is 130–330 V per phase and can be extended to 60–380 V to order. Accuracy is within 1 %, efficiency 98 %, response time 1 ms and output 220 V per phase. The module per phase measures 640×320×122 mm and weighs 14.2–17 kg. Cooling is natural convection plus forced. Double energy conversion cuts off network surges and noise, and each phase works independently.
How to choose
Pick the model by load current per phase, from 16 A to 63 A. If ±0.5 % accuracy is required, look at Prostor or Parus for 21–42 kW. Loads above 42 kW are covered by the Smart range up to 81 kW. Supplied as the official representative in Ukraine.

FAQ
Does the light flicker when EtalonS is working?
No, regulation is stepless, so there is no flicker and no voltage jumps for sensitive electronics. The output holds 220 V per phase.
When does EtalonS cut off in transit mode and how fast does it start?
The transit cut-off is set at 260 ± 5 V and the start-up delay is 4.5–7.5 s.
What are the noise level and ingress protection of EtalonS?
Noise is 34–40 dB depending on load and ingress protection is IP20. The unit is meant for indoor use at +1…+40 °C and 40–80 % humidity.
Can the input range of EtalonS be extended?
Yes, a 60–380 V version is available to order, while the standard range is 130–330 V per phase. Frost-resistant treatment is also available to order.
