DESCRIPTION: The Volter-81 pt is a three-phase thyristor voltage stabilizer consisting of three high-precision 27 kW stabilizers. This Volter stabilizer is designed for continuous 24-hour operation and is installed permanently throughout a home (apartment, office, or industrial equipment). It is connected via a terminal block, in a phase break at the input, immediately after the meter. The stabilizer does not contain any mechanical components, including a fan (convection cooling is provided). The Volter™-81 pt (3*27) is capable of operating in freezing conditions, allowing it to be installed in an unheated room. The stabilizer provides the ability to adjust the output voltage up or down by 15 volts in 1 volt increments. This feature is useful if your consumers require a voltage different from 220 volts (for example, 230 volts). Advantages: Quiet operation, Improved heat dissipation without a fan, Increased noise immunity, High speed, Operation at sub-zero temperatures and high humidity, Improved fire safety, Maintenance-free, Maximum number of protections, Convenient connection, No sine wave distortion, Resistance to mechanical impact, High overload capacity, Increased reliability. Optimal reliability/price ratio.
