Single-phase and three-phase motor-controlled AC/DC power sources for reliable supply to the load applications. The output voltage is set either manually or automatically using the ACTAS software with the aid of variable voltage transformers controlled by servomotors. Output values and operating statuses are clearly displayed on status displays. The power source is short-circuit proof and protected against overload conditions.
