Voltage regulator Volter - 4птм

PTM-4 - single-phase voltage regulator for an apartment or house maximum capacity 3,5kVt relates to a new series of Volter PTM. This double conversion apparatus without accumulation of energy.
stabilizer provides no influence on the output voltage changes as the input voltage and surges and load changes. For this purpose it comprises a voltage source model with the mains frequency and a stable value which continuously compares the output voltage of the stabilizer. Due to this construction of the stabilizer, it does not react even at very sharp, almost instantaneous changes in the input voltage, and very quick to respond to any change in load. Just realized independent from the type of load, ie the stabilizer works equally active, capacitive and inductive load if the output current does not exceed the permissible output current.
In order to eliminate overheating and trip the thermal protection under severe operating conditions (full load, high ambient temperature) voltage regulator equipped with a forced cooling system, which is triggered by increasing the temperature in the device for more than 60 ° C. To eliminate the noise, two fans are used, operating at low speed.
