Variable Transformer 120-600 VAC, up to 1000 kVA
Continually variable output voltage that can be adjusted from 0 to 117% of the unit’s input.
(1010B rated at 120VAC and 1.56 kVA shown)
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:
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.
