1000 Series
STACO’s 1010B operates on 120 volts and is rated for con-
stant current of 10 amperes. The 1020B operates on 240 volts
and constant current of 3.5 amperes. Coil tapping arrange-
ments allow for 0 to input line voltage or 17% above line volt-
age. These variable transformers may be operated from 50-
1500 hertz with no reduction in output current.
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, which have a
“CT” suffix, feature the protective screening over the coil

Jumper provided in the standard common position and should be moved or removed
as required.
Unit is fused for the constant current rating at the factory.
Motor driven units use terminal connections for CCW increasing voltage, as viewed
from the base end. See Fig 23 on page 9 for motor wiring.
Maximum KVA at maximum output voltage and corresponding derated output cur-
rent. Maximum KVA for lower voltages may be calculated from derating curve Figure
B, page 6.

assembly and a terminal box cover 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
terminals of the variable transformer assembly. If the system has no neutral, the load
must be balanced or the transformers will be damaged.
Maximum output current in output voltage range from 0 to 25% above line voltage. At
higher output voltages, the output current must be reduced according to the derating
curve, Figure B, page 6.
