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 direc-

tion. Two and three ganged, manually operated units are avail-

able for increased single phase voltage ratings and for three

phase applications.
