Series 100/200 l l 0.8 to 3.0 Amperes

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.

If the system has no neutral, the load must be balanced or the transformers will be damaged. 120V 240V TYPE B TYPE A 291 2.31” [58.7]
