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.
The 1010B operates on 120 volts and is rated for constant
current of 10 amperes.
- High efficiency - 80%
- Distortionless Voltage Control
- Simple installation and connection
- Longer life with negligible maintance
- Smooth and liner voltage control
