Single-phase stepped thyristor voltage stabilizers Volter 9–27 kW and PROM series 22 kW
Country: Ukraine · Model: S / PT / PTS / PTSh / PTSSh / PROM
Single-phase stepped thyristor stabilizers Volter rated 9, 11, 14, 18, 22 and 27 kW level the voltage in 20 ms by switching transformer taps. A separate PROM series of 22 kW is made in PT, PTS, PTSh and S versions for harsher conditions. They go into workshops, small production units, pumping stations and shops.

Description
There are no moving parts and cooling is natural, so maintenance is minimal. Current by model is 40 A at 9 kW, 50 A at 11 kW, 63 A at 14 kW, 80 A at 18 kW, 100 A at 22 kW (PROM included) and 125 A at 27 kW. The enclosure at 9–14 kW measures 350×420×160…190 mm and weighs 21–37 kg, and at 18–27 kW it is 650×420×190 mm and 50–67.6 kg. Output is 220 V, efficiency 98 %, the transit cut-off is 260 ± 5 V and the turn-on delay 4.5–7.5 s. Protection acts against overload, short circuit, overheating and overvoltage, and IP20 calls for an indoor room at +1…+40 °C and 40–80 % humidity. Frost-resistant treatment is made to order.
How to choose
The S version gives ±6.5 % on 9 steps with a 125–265 V input. PT works with 16 steps, +2/−3 % and an input of roughly 145–245 V, and PTS moves the input to 170–265 V. For large swings PTSh holds +3.5/−5.5 % at 110–250 V, while PTSSh covers about 145–285 V. For stepless regulation look at the inverter Smart, and the European analogues of the single-phase models in the catalogue are rated 20–400 A. Supplied as the official representative in Ukraine.

FAQ
What current do the 9 kW and 27 kW models handle?
The 9 kW model is rated 40 A, the 27 kW model 125 A, and the 22 kW including PROM 100 A.
How fast are the single-phase thyristor stabilizers?
Tap switching takes 20 ms and efficiency is 98 %.
How do the S and PT versions differ?
S has 9 steps and ±6.5 %, PT has 16 steps and +2/−3 %, so PT levels the voltage more tightly.
What conditions is the PROM 22 kW series meant for?
PROM at 22 kW is made in PT, PTS, PTSh and S versions for harsher operating conditions.
