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 control.
• 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.
