The 5011/5021 Series Variable transformers are designed to
control large KVA requirements. The 5011 operates on 120
volts and is rated for constant current of 50 amperes. The 5021
operates on 240 volts and constant current of 28 amperes. The
5011 Series units have coil tapping arrangements allowing out-
put voltage from 0-117% of line voltage, while the 5021 Series
allows output voltage from 0 to line voltage or 17% above line
voltage. They can be operated at frequencies between 50 and
400 Hertz with a rating at higher than rated frequency.
Adjustable shaft design on manually operated models permits
back-of-panel or bench mounting. Terminals are 1/4” screw
type. For single and two ganged units, case styles are available
in either “C” style, which encloses only the coil, or the “CT” style,
which provides protective housing for both the coil and terminal
board. Knockouts are provided in the terminal board housing to
accomodate conduit or cable connections. For three ganged
and above, we offer our Nema 1, dripproof, fully front accessi-
ble “E” enclosure.
Motor-driven models are available from single thru 27 ganged
assemblies; cased or uncased (identified with the prefix “M” in
the part number). The synchronous motor is designed for
operation on 120 volt, 50/60 Hertz, single phase lines and
draws approximately 0.3 amperes. To meet a wide range of
application requirements, standard motor speeds of 5, 15, 30
and 60 seconds are available depending upon the size of the
variable transformer.
