Three-phase inverter voltage stabilizers Volter Parus 21–42 kW (3×7 … 3×14)
Country: Ukraine · Model: Parus-21 – Parus-42
Parus is a set of three-phase inverter stabilizers rated 21, 27, 33 and 42 kW with stepless regulation and ±0.5 % accuracy. Each phase sits in its own vertical module with forced cooling, and the response time is about 1 ms. The series is used in production sites, workshops, shops and warehouses where accurate voltage stabilization is required.

Description
Parus-21 (3×7) at 32 A, Parus-27 (3×9) at 40 A, Parus-33 (3×11) at 50 A and Parus-42 (3×14) at 63 A have a 130–330 V per phase input range, which can be extended to 60–380 V to order. The 630×430×140 mm module weighs 19.5 kg, while that of Parus-33 is smaller at 610×415×125 mm and weighs 14.2 kg. The shared double-conversion circuit keeps surges and noise away from the output. The output is 220 V per phase and efficiency 98 %. The transit cut-off occurs at 260 ± 5 V and the start-up delay is 4.5–7.5 s.
How to choose
The choice comes down to current per phase, from 32 A to 63 A. Parus-33 has a smaller module, so it needs less room. If a low, wide housing is wanted, there is Prostor with a 290×785×215 mm module, while Smart for the same 21–42 kW has slimmer modules of 555×360×60 mm (21 kW) and 700×320×120 mm (27–42 kW). Supplied as the official representative in Ukraine.
