Auto Variable Transformer Details

Variac is most effective equipment for stepless correction, breakless & continuous control of ac voltage. It is generally used in testing purposes, varying voltage requirement in any application as wll as manufacturing in servo voltage stabilizes. Variac is pure copper wound on toroidal lamination an effective instrument to control the voltage as per requirement. Output voltage can be enhanced as per requirement upto 300v in single phase and upto 500 volt in three phase. It can also be customized with option of motorized or manual mode. The mode of cooling will be air cooled or oil cooled.

Auto Variable Transformer Benefits

  • Allows you to increase or decrease voltage gradually without sudden jumps.
  • Can provide precise voltage adjustment from zero to maximum output.
  • Helps protect sensitive devices by delivering the exact voltage they need.
  • Used in laboratories, testing equipment, industrial machines, and home appliances.
  • Converts power with minimal energy loss, making it cost-effective.

FAQ'S

A Variac works by using a rotating dial or knob to smoothly adjust voltage from zero to maximum without jumps. It does this by changing the connection point on a single winding coil, controlling how much voltage is delivered.

A Variac is used in labs, industries, and homes for testing electronics, motor speed control, light dimming, and heating devices. It provides precise voltage adjustment for safe and efficient operation.

No, it is not an isolation transformer; it shares a direct connection with the power source.

Yes, but only if the appliance is designed to work with variable voltage (e.g., old radios, motors, or heating elements).

Yes, but carefully! You need to set the correct voltage and use a current-limiting circuit to avoid overcharging.
