Voltage stabilizer Volter-21 ptsh (3*7)
The Volter 21 PTSh is a three-phase voltage stabilizer for an apartment or home with a maximum power of 21 kW. It belongs to the Volter PTSh series, featuring increased accuracy and a wide input voltage range. It is designed to provide stabilized voltage to all types of electrical consumers when powered from a grid with unsatisfactory voltage quality.
We provide a lifetime warranty on Volter products. The operating stabilization range is from 145 to 285 V. This device balances phase voltage to a nominal 220 V, taking into account GOST deviations.
