• Stepper Motor Driven
• M i c ro p rocessor Contro l l e d
• Self-contained, Factory Wi red and Assembled
• Local or Remote Adjustable Output Voltage Range
• Regulated Output Voltage, ± 0.50 percent of Full Voltage Range
• Low Installed Cost
The “Quick-Step” is self-contained and consists of a stepper motor
a 0 to 100 percent adjustable output voltage range. The “Quick-Step”
is shipped fully assembled, factory wired and tested ready to be
installed … two wires in, two wires out. The “Quick-Step” is named for
Cased Models (C and CT Types)
Transformers of the 1010B through 6011 series are available in either
“C” style (featuring protective screening over the coil assembly only) or
the “CT” style (which also includes a terminal box cover with knockouts
to accept conduit). Examples: 1510C, 2510CT.
Motor-Driven Models
For applications requiring remote or automatic voltage control, a driving
motor can be added to all models of the 501C through 6011 series.
S t a n d a rd motor speeds available are 5, 15, 30 and 60 seconds of travel
and are designated by the prefix “5M,” “15M,” etc. Example: 30M1510.
Complete details of all standard Staco products are contained in our Variable Transformer Voltage Control Catalog (VT-5).

Microprocessor Controller
its fast full range output voltage correction rate which is less than one
second. The microprocessor controlled stepper motor provides a quick
output voltage adjustment without over shoot. The output voltage can
be controlled remotely with a 1K potentiometer or a 0 to 5 volt DC
process control set point signal. A single output voltage can be main-
tained and controlled locally with a fixed resistor network wired across
the controller set point terminals.
The “Quick-Step” Variable Transformer is available in ratings of 3 to 25
amperes with output voltage ranges of either 0 to 120 volts or 0 to 140
volts. Full range output regulation is better than ± 0.50 percent. Limited
regulation of better than ± 0.25 percent. Being self-contained, provid-
ing a low installed cost makes the “Quick-Step” a real … “Staco-Plus.”
Microprocessor Controller
MP Series Microprocessor Based Controller provides for easy interface
of computer and process controller to Staco’s motor driven Variable
Transformers. Custom options are available.
FRC-20 Controller
The Staco FRC-20 Controller is designed to position and regulate any
Staco motor driven variable transformer and can be controlled with a
0-5 VDC or 4-20 Ma set point, a 1k ohm potentiometer, or a fixed resis-
tor network. It maintains a full range regulation of 0.5 percent and a lim-
ited range regulation of 0.25 percent.
