Controller A3RW10,0/1/S/IP 21 17886-9977

Three-phase fan speed controller

The A3RW10,0/1/S/IP 21 controller is a reliable device designed for five-stage control of the rotational speed of three-phase motors, mainly used in ventilation and heating systems. The controller's design is intended for demanding working conditions in professional installations. The device is characterized by solid construction and a high level of protection, ensuring safe and efficient operation.

Construction and application

A3RW is an autotransformer regulator, which means it changes the voltage supplied to the fan motor, thereby controlling its rotational speed. It has a knob for manual adjustment of the regulation level - five positions are available. The device is adapted to cooperate with motors with a voltage of 400V (50/60Hz). The IP21 degree of protection ensures resistance to the ingress of solid objects larger than 12.5 mm and to condensation, allowing installation in environments with moderate humidity and dust. Thanks to this, the regulator will work well both in industrial halls and in public buildings.

Key features and benefits

• Versatile application: The regulator is designed to work with motors with an output current of up to 10A, making it a universal solution for various ventilation systems.

• High level of safety: Equipped with a fuse and anti-freeze and thermal protection, it protects both the regulator itself and the connected device from damage caused by overload or failure.

• Durable construction: The IP21 degree of protection guarantees resistance to difficult working conditions, ensuring long-lasting and trouble-free operation.

• Simple operation: The intuitive knob allows easy and precise adjustment of the fan speed.

• Backlight: Built-in backlight in the ON position makes it easier to operate the device in dimly lit rooms.

• Three-phase system: Designed to operate in three-phase networks (3 phases), which is standard in most industrial and commercial installations.

• Five-stage regulation: Allows precise adjustment of the fan speed to current needs, optimizing energy consumption and user comfort.

The A3RW10,0/1/S/IP 21 controller is a solid choice for installers looking for a reliable solution for controlling the speed of three-phase fans and for end-users who value the efficiency and safety of the ventilation system.
