Staco Energy Products' full range of variable transformers offer the exceptional versatility and reliability required for so many of today's voltage control applications in both industrial and laboratory environments.
Unlike a standard fixed ratio transformer, a Staco variable transformer is designed to provide variable output voltage that can be adjusted from 0 to 117% of the unit's input voltage.
Staco Energy Products Co. offers a wide range of standard models including the following:
- Panel mount, single phase (fixed and adjustable shaft)
- Enclosed cord and plug
- Metered
- Fully enclosed
- Ganged
- Isolated
- Isolated portable cord and plug models
- “Quick-Step” motorized
- Motor driven
- Cased
A basic Staco variable transformer consists of a copper winding on a toroidal core of laminated, grain-oriented, silicon steel. A carbon brush, connected to an output terminal, is rotated over the length of a precision-ground, precious metal-plated, commutator track to tap off voltage at any turn from zero volts to the maximum output voltage of the winding.
