Speed controller ARW 3.0/2 AC 1-4-0101-0434

Fan motor speed controller

This speed controller, model ARW 3.0/2 AC, is a transformer device designed for smooth speed control of single-phase powered fan motors. It allows precise adjustment of the airflow to current needs, which translates into user comfort and energy efficiency of the ventilation or heating system.

Features and application

The ARW 3.0/2 AC controller is widely used in industrial installations and public buildings. It works perfectly in water heaters, ventilation and heating systems, where control over fan performance is necessary. Thanks to the stepped regulation, it is possible to optimally adapt the device's operation to the conditions in the room.

• 5-stage regulation: Allows precise setting of the motor speed, which translates into accurate control over the airflow.
• Load capacity 2.5 A: Ensures compatibility with a wide range of fan motors with appropriate power.
• Durable construction: A housing with IP54 protection degree guarantees resistance to dust and moisture, enabling installation in difficult industrial conditions.
• Safety of use: Equipped with an automatic thermal switch protecting the transformer winding against overload.
• Operating indicator: An independent illuminated switch informs about the controller being switched on.
• Compliance with standards: Manufactured in accordance with EN 61558-2-13 standard ensures safety and reliability of operation.

The controller is adapted for mounting inside an enclosure (enclosed type) and is characterized by compact dimensions (96x166x91 mm). This makes it easy to integrate with existing installations. The weight of the device is 2.5 kg. The insulation class is II, and the insulation thermal class is B (130°C). The maximum ambient temperature for the controller to operate is 40°C.
