BP2-1-300, BP3-1-300 Switch

It is used to switch on/off and change the speed of fans which are based on multi-speed motors.
BR-S1/010 potentiometer

Potentiometer designed to set the desired speed value for fans equipped with electronically commutated EC motors. The potentiometer requires a power source max 10-12V DC / 1mA, which is available from the EC fans. The output is a stepless 0-10 V DC signal. Resistance 10 kΏ.
BR-TWIN 1-010 potentiometer

The BR-TWIN 1-010 EC potentiometer is designed for electronically commutated EC motors. It allows for setting two speeds and has a NO input (e.g. for a timer or CO2 sensor). The potentiometer is supplied with a signal up to Uc max = 15V. It has enclosure protection class IP 65.
CSR-B Controller

CSR-B EC W, CSR-B EC Zero Plus W, CSR-B EC NFC W controller
Controllers of the CSR-B series are constant pressure regulators designed for cooperation with duct and roof fans with EC motors. By continuously controlling the fan speed, they ensure constant pressure in the ventilation ducting. Based on a PI controller, CSR-B controllers have the option to set a constant fan power and programmable upper and lower fan control limits.
thyristor speed controller BS 1.5

Used in ventilation systems to switch on/off and regulate the speed of single-phase electric motors of voltage-controlled fans.
thyristor speed controller BS 1.8

Used in ventilation systems to switch on/off and regulate the speed of single-phase electric motors in voltage-controlled fans.
