Controller A3RW14,0/1/S/IP 21 17886-9976
Three-phase fan speed controller A3RW14,0/1/S/IP 21
This autotransformer-based speed controller A3RW is designed for five-stage speed control of three-phase powered fan motors. This device is ideal for professional ventilation and heating installations where precise airflow control is crucial. Model A3RW14,0/1/S/IP 21 is distinguished by its solid construction and high level of protection, ensuring reliable operation in demanding conditions.
Construction and application
The A3RW controller is designed for durability and functionality. Its housing with IP21 protection rating protects against the ingress of solid objects larger than 12.5 mm and dripping water, allowing installation in industrial and technical environments. Five-stage speed control via a knob allows you to adjust the fan performance to current needs. The device is particularly useful in HVAC systems (heating, ventilation and air conditioning), where optimizing fan operation translates into energy savings and user comfort.
Advantages and benefits
- Versatility: The controller's output current is 14A, making it suitable for a wide range of fan motors.
- Safety: Equipped with a fuse and freeze and thermal protection, it protects both the device and the electrical installation from damage.
- Durability: Solid construction and IP21 protection rating ensure resistance to harsh working conditions.
- Ergonomics: Intuitive operation with a knob makes it easy to adjust the rotational speed.
- Reliability: Proven design and high-quality components guarantee long-lasting and trouble-free operation of the device.
- Universal voltage: The controller is adapted to work with a voltage of 3x400V 50/60Hz, ensuring compatibility with most electrical installations.
- Backlight: It has a backlight in the ON position, which makes it easier to read the device status in low light conditions.
The A3RW controller is an investment in the efficient and safe operation of the ventilation system – both for professionals involved in installations and for end-users who value reliability and comfort.
