1500 Series
The 1510/1520 Series Variable Transformers are highly reliable,
dependable and accurate AC control devices. The 1510, 120 volt
unit is rated at 15 amperes for constant current loads; while the
1520, 240 volt unit is rated at 9.5 amperes for constant current
loads. Constant impedance ratings are listed in the specifications.
They can be operated at frequencies between 50 and 2000 hertz
with derating at higher than rated frequency.
Uncased models have the shaft extending from the base end.
This shaft is fully adjustable and can be extended from either end
for general utility mounting. Cased styles are available in either
“C” style (featuring protective screening over the coil assembly

with knock-outs to accept conduit).
Motor driven units are available in single, two and three ganged
assemblies; cased or uncased styles as identified by the prefix
“M” in the type number. 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.
The synchronous motor is designed for operation on 120 volts,
50/60 hertz single phase lines and draws approximately 0.3
amperes.

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 ter-
minals of the variable transformer assembly. If the system has no neutral, the load must be
balanced or the transformers will be damaged.
