DESCRIPTION: The Volter-11 pt is a single-phase, 11 kW, high-precision voltage stabilizer. It contains no mechanical components, including a fan (convection cooling is used). This allows you to use it in applications requiring quiet operation. ADVANTAGES: Quiet operation, Improved heat dissipation without the use of a fan, Increased noise immunity, High response speed, Can be used at sub-zero temperatures and in high humidity, Improved fire safety, Maintenance-free, Maximum number of protections, Convenient connection, Does not distort sine waves, Resistant to mechanical impact, High overload capacity, Increased reliability. Optimal reliability/price ratio Characteristics: Type - electronic thyristor Phase - single phase Efficiency, % - 98 Input range - 145-245 V Response time, ms - 20 Noise level, dB - 34-40, depending on load Maximum current, A - 50 Maximum power, kW - 11 Mounting method - wall-mounted / floor-standing Cooling - natural Max.
