Three-phase inverter voltage stabilizers Volter Smart 10.5–81 kW (3×4 … 3×27)
Country: Ukraine · Model: Smart-12 – Smart-81
Smart is a range of three-phase inverter voltage stabilizers from 10.5 to 81 kW, each built from three single-phase modules, one per phase. The output stays at 220 V per phase with ±0.5 % accuracy and a response time of 1 ms. They suit workshops, pumping stations, boiler houses and sites powered by a generator or a solar plant.

Description
The range has nine models. Smart-12 (3×4) is rated 10.5 kW and 16 A, Smart-16.5 (3×5.5) 25 A, Smart-21 (3×7) 32 A, Smart-27 (3×9) 40 A, Smart-33 (3×11) 50 A, Smart-42 (3×14) 63 A, Smart-54 (3×18) 80 A, Smart-66 (3×22) 100 A and Smart-81 (3×27) 125 A. Each phase is regulated separately, so load imbalance does not spoil accuracy. Double conversion without energy storage keeps input surges and pulses away from the output. The input range is 110–330 V per phase, with an upper limit of 380 V for 27–42 kW and 130–330 V for 54–81 kW. An extended 60–380 V input and frost-resistant treatment are available to order. The module per phase measures 555×360×60 mm for 12–21 kW, 700×320×120 mm for 27–42 kW and 1100×335×155 mm for 54–81 kW, weighing 8.8–8.9 kg, 13.9–14.2 kg and 20.2–26.9 kg respectively.
How to choose
Power is chosen by the current of the most loaded phase. Loads up to 42 kW are covered by Smart-12 to Smart-42, and from 54 kW upward Smart-54, Smart-66 or Smart-81 apply. If 105 kW at 160 A per phase is needed, Smart-100 delivers it with a 130–300 V input range. Supplied as the official representative in Ukraine.

FAQ
What are the efficiency and response time of Smart?
Efficiency is 98 %, response time 1 ms, and output voltage 220 V per phase. Regulation is stepless with ±0.5 % accuracy.
When does Smart switch 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 Smart?
The noise level is 34–40 dB depending on load, and ingress protection is IP20. The unit therefore goes indoors at +1…+40 °C and 40–80 % humidity.
Can Smart run from a generator or a solar plant?
Yes, the range works from a generator and is compatible with the green tariff.
