Staco Energy Products Co. has been a leading manufacturer of vari-
able transformers for over 60 years, building standard as well as cus-
tom-designed products for industrial, commercial and military applica-
tions. Variable transformers have many industrial and laboratory appli-
cations as basic components to control voltage, current, power, heat,
speed, light and electromechanical force.
A basic Staco variable transformer consists of a single layer, magnet
wire, winding on a toroidal core of laminated silicon steel. A carbon
brush, connected to an output lead, is rotated over a precision ground,
plated commutator track to tap off voltage at any turn from zero to the
maximum output voltage of the winding.
Staco re s e a rch has developed design features and pro p r i e t a ry
processes providing longer lasting, more reliable products. Particularly
important is the high-temperature foundation material bonding the coil
securely to the core assembly. This material, which has a high thermal
transfer characteristic, dissipates heat from the brush contact area,
increases the heat-distribution of the core itself and provides the trans-
former with greater tolerance to transients and short-term overloads.
In addition to the basic styles illustrated, Staco can meet your specif-
ic requirements with hundreds of additional standard model variations

To serve your needs promptly, Staco has a national network of stock-
ing distributors to assure immediate off-the-shelf delivery. Your local
Staco distributors and representatives are factory trained personnel
capable of assisting you in selecting the particular Staco transformer
best suited for your application.
Contact our factory for the name of the distributors and representa-
tive in your area.
For non-standard products (to meet your special application) Staco’ s
engineering staff will quickly respond with solutions to your applica-
tion requirements. Most of the time, it merely requires minor revisions
to standard components, enabling Staco to keep your costs at a min-
imum.
