Autotransformer A3RM10,0/1 17786-9982

A3RM10,0/1 autotransformer is a three-phase speed controller, dedicated to controlling fan motors in industrial installations. The device enables five-stage speed control, which translates to precise adjustment of the ventilation or heating system's performance to current needs.

The autotransformer's construction is based on the use of autotransformer taps, brought to an electrical connection. This solution ensures reliability and durability, and the open design facilitates mounting in existing installations. Construction in Class I insulation and compliance with EN61558-2-13 standard guarantee safe operation.

The device is characterized by a wide range of output currents (up to 14A) and a supply voltage of 3x400V (50/60Hz). Five stages of output voltage regulation (400;
