Variable Transformers, generically referred to as "Variac", are widely used when adjustable voltages are required for quality control testing, electronic equipment burn-in, life-tests, low voltage performance evaluation, D.C. rectifier/regulator analysis or other engineering applications.

Variacs are also frequently used to adjust temperature, control lighting, hot wire plastic cutting operation control and, to a lesser extent, for speed control.

When combined with a voltage regulator, a well regulated, wide range AC voltage source can be achieved.

A variac combined with an isolation transformer can be used to safely provide variable voltage to equipment isolated from AC power lines.

Variac features and choices:

  • Precise, continuous voltage control
  • 60 Hz and 50/60 Hz Models available
  • Bench-Top and Panel-Mount Models
  • Motorized Models can be factory ordered
  • 120 Volt and 240 Volt Models
  • Three-Phase Models can be Special Ordered
  • Autotransformer design gives voltage boost

    Availability: Stock to 2 weeks
