Volter 7 PTTM — single-phase voltage stabilizer

Volter 7 PTTM — single-phase voltage stabilizer for an apartment or house with a maximum power of 7 kW, belongs to the Volter PTTM series. The stabilizer eliminates both deep voltage drops and small surges.

The stabilizer ensures that the output voltage is not affected by changes and surges in the input voltage, as well as changes in the load. To achieve this, it contains a reference voltage source with a stable value at the network frequency, with which the output voltage of the stabilizer is continuously compared.

Thanks to this design of the stabilizer, it does not react even to very sharp, almost instantaneous changes in the input voltage, and very quickly responds to any change in the load. Load independence is also implemented—the stabilizer operates equally with active, capacitive, and inductive loads, as long as the output current does not exceed the permissible value.

To prevent overheating and thermal protection under severe operating conditions (full load, high ambient temperature), the stabilizer is equipped with a forced cooling system that is activated when the internal temperature exceeds 60°C. Two fans operating at low speeds are used to eliminate noise.
