The voltage regulator works through moving the brush on the surface of regulating winding to change the voltage

Working Principle:

Column contact voltage regulator works through moving the brush of the winding axiel on the surface of regulating winding to change the voltage.

Its electric principle is similar to the circline voltage regulator, because of its special structure and design from others, which make the manufacturing of high-capacity voltage regulator simple and feasible.

Performance Features:

1.low impedance voltage (50% U2 ≤ U2 ≤ 100% U2): UK ≤ 7%

2. less output voltage lower limit: U2min ≤ 1% U2max

3.less distortion output voltage waveform  ≤ 3%

4.output voltage and input voltage with the same phase

5. output voltage characteristic curves: linear

6.manual available,or electromotion with stepless&continuous regulating output voltage

7. brush contact with no spark

8. if DC motor is applied for servo motor, the voltage regulating speed can be adjusted in a certain range.

9. Low Noise ≤ 60dB
