DESCRIPTION: The Volter-27 pt is a single-phase, 27 kW voltage stabilizer with increased accuracy. It contains no mechanical components, including a fan (convection cooling is provided). This allows you to use the stabilizer 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, Increased fire safety, Maintenance-free, Maximum number of protections, Convenient connection, Does not distort the sine wave, Resistant to mechanical impact, High overload capacity, Increased reliability. Optimal reliability/price ratio Characteristics: Type - electronic thyristor Phase - single phase Efficiency, % - 98 Input range - 140-250 V Response time, ms - 20 Noise level, dB - 34-40, depending on load Maximum current, A - 125 Maximum power, kW - 27 Dimensions (H x W x D), mm - 650 x 420 x 190 Mounting method - wall-mounted / floor-standing Cooling - natural Output voltage - 220 V Stabilization accuracy - +2.5 -3.5% Number of stages - 16 Stabilization step - 7 V Max.
