Circuit variants - single-phase operation
- star circuit with accessible star point
- open delta circuit
- economy circuit with master-slave principle and subsidiary U 2 control
in burst-firing operation
- free-running economy circuit (star or delta), only with subsidiary P control
in burst-firing operation
Operating modes - phase-angle operation for resistive and transformer loads with soft start
(with extra code TR, TO with current limiting)
- burst-firing operation for resistive or transformer load.
