WIRING DIAGRAM FOR AC VOLTAGE STABILIZER
This wiring diagram is an example of how to use feedback input 3 to maintain a constant load voltage. In this case the feedback
signal (Vmax 250Vac) is taken directly from the secondary winding of the transformer that is used to raise the voltage to recover
mains voltage dips. For highter voltages, or for isolation purposes, use a voltage transformer with a low voltage secondary winding.
NB. To use this application make sure that the load accepts a partialized waveform power source.
- Close microswitches 1 - 3 - 4 - 6 - 7 - 8.
- Adjust:
> trimmers P1 - P2 - P4 fully clockwise
> trimmer P3 to set the required load voltage .

CURRENT CONTROL (TORQUE) OF A SINGLE PHASE ROWAN AD HIGH SLIP MOTOR
This diagram is an example of how to use feedback input 2 to limit the load current. In this case the load is a ROWAN high slip
motor. This setup will control the motor torque at all speeds and use it as a static clutch.
The current is controlled by a current transformer (TA) with an end scale of 4Vac\0.2A supplied by ROWAN.
- Close microswitches 1 - 3 - 6 - 7 - 8 - 9.
- Adjust:
> trimmers P1 - P2 fully clockwise
> trimmer P9 to set the maximum current regulation by potentiometer (maximum 80% of rated motor current).
