Series 100/200 l 0.8 to 3.0 Amperes
100/200 Series
These manually operated panel mounted units are available in
single and three phase models from 0.8 to 3.0 amperes. The
171, 201, 221-B and 291 units operate from 120 volt input,
while the 252 unit operates from a 240 volt input. STACO’s coil
tapping arrangement permits an output voltage from 0 to line
voltage in either the clockwise or counterclockwise direction
and from 0 to 10% above line voltage in the clockwise direction.
Two and three ganged, manually operated units are available
for increased single phase voltage ratings and for three
phase applications.

++ Line to line voltage
π 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.
