Thyristor regulator REB-1N, surface-mounted for single-phase fans (230V) with power above 20W and below 230W, dimensions 80x80x68 40025010

Fan speed controller REB-1N

This thyristor controller is designed for smooth speed control of single-phase (230V) fans with a power of 20W to 230W. The device is surface-mounted and equipped with an integrated switch, providing convenience and safety. REB-1N is a simple but effective solution for controlling ventilation performance in various applications – from domestic to industrial.

Application and functionality

The REB-1N controller allows you to adjust the airflow to current needs, which translates to user comfort and energy savings. By reducing the supply voltage to the fan, the controller enables reducing its rotational speed, and thus limiting noise and power consumption. This is particularly useful in situations where the full power of the fan is not required, e.g. at night or during cooler days.

Construction and mounting

The device is characterized by a compact design (dimensions 80x80x68 mm) and easy surface mounting. It has the ability to adjust the lower setting range, which allows for precise adjustment of the minimum fan speed to specific installation requirements. The switch integrated with the controller facilitates operation and provides additional safety.

Important notes regarding use:

• Thyristor controllers may generate motor noise at low speeds - it is recommended to avoid reducing the speed below 50% of the nominal value.
• The device only works with fans adapted to speed control by changing the supply voltage.
• The maximum load of the controller is 1A (230W).
• Remember to select the controller correctly for the fan power to ensure its proper operation and avoid damage.
