A POWERSTAT Variable Transformer is a precision product packed with care.
When unpacking, examine carefully for any shipping damage. Inspect the brush
contact with particular care. The “Damage and Shortage” Instructions packed
with the unit outline the proper procedure to follow if any parts are damaged
or missing.
NOTE- The unit should be protected from any dust or debris that may be
encountered while drilling holes, installing wiring, etc, during installation.
POWERSTAT Variable Transformer types within this Series have two sets of
mounting holes to facilitate installation in new or existing layouts. Use the set
that is most convenient for the application. All models are designed so that
the same unit can be either bench or back-of-panel mounted as desired. The
units as shipped are arranged for bench mounting. To change to back-of-panel
mounting, proceed as outlined.
Models 3PN116C, 3PN117C, 3PN216C and 3PN217C have a cord and plug
input and a receptacle output, and are usually used as a portable source of
variable a-c voltage. If desired they may be mounted in the same manner as
other manually operated single units.
BENCH OR WALL MOUNTING
1. Using Drilling Template No. 1, locate and drill the desired set of mounting
2. On open construction models (“U” types), loosen the shaft setscrews in the
3. Place the unit in position and insert and fasten ¼” mounting screws.
4. For “U” types, provide a support for the dial. Mount the dial to the support.
5. In addition, on enclosed terminal (“T”) types, remove the terminal cover and

With ordinary care, a POWERSTAT Variable Transformer should require no
servicing except possible replacement of the brush assembly. The brush should
be inspected periodically and replaced if arcing takes place or if it is badly worn.
Because the brush must be of a special material, replace only with a Superior
Electric brush assembly. The assembly is designed to assure perfect contact
of the brush to the commutator regardless of brush position and length of time
in use. Take care to avoid scraping, scratching or marring the commutator
surface. Follow these steps to install a new brush assembly:
1. Unfasten the two brush anchor screws, remove and discard the old brush
2. Insert the new brush assembly. Be sure that the tang on the back of the
3. Raise the brush and place a piece of sandpaper (grit #400 or finer) between
4. While holding the sandpaper in place (flat), rotate the brush through a short
5. Rotate the brush over the full range several times to check for smooth travel
