Versatility, compactness and durability are included in the many
designed-in features of the STACO 501C Series Variable
Transformers. These transformers operate from 120 volt input
lines and are rated at 5 amperes for constant current loads and 7
amperes for constant impedance loads at line voltage. The coil
tapping arrangement permits output voltage of 0 to line voltage or
17% above line voltage on constant current line conditions. This
unit’s Faston
with the terminal adapter kits supplied with each unit.
The STACO 511 is ideal for OEM applications with its panel
mount, fixed shaft design and even smaller envelope than the
501C
511
Unit is fused for the constant current rating at the factory.
Jumper provided in the standard common position and should be moved or
removed as required.

501C. it can be single point or four point mounted. The four point
mounting is the same as the 501-C.
Either unit can be operated from 50-2000 hertz without derating.
Motor driven units are available and identified by the prefix “M” in
the type number. The synchronous motor is designed for opera-
tion on 120 volt, 50/60 Hertz single phase lines and draws
approximately 0.3 amperes. If a motor driven model is ordered,
be sure to prefix the part number with the desired travel time from
0 to maximum of 5, 15, 30, or 60 seconds.

If ganged units are used in a system that ordinarily has a common neutral or
ground between source and load, the neutral or ground must be connected to
the common terminals of the variable transformer assembly. If the system has no
neutral, the load must be balanced or the transformers will be damaged.
Motor driven units use terminal connections for CCW increasing voltage as viewed
from the base end. See figure 23 on page 9 for motor wiring.
