Metal Shell Single Phase Voltage Regulator , Wide Range Voltage Adjuster 500VA .

The Voltage regulators ( Variac ) are used to adjust the voltage from 0 volts up to the maximum voltage for which they have been designed and among the most usuall applications . No additional wave from distortion . The main applications are :

• Laboratory control equipment .
• Lighting equipment .
• Temperature controls .
• Motor speed contro l.
• Controlling of other transformers .
• Etc .

Manually Operated Rotary Knob to control output voltage , by means of a control button on the shaft of the voltage regulator ( Variac ) which allows to act on the brush and achieve the desired voltage . The voltage can be smoothly varied between turns as the brush has a relatively high resistance ( compared with a metal contact ) and the actual output voltage is a function of the relative area of brush in contact with adjacent windings .
