The Airtechnic 4T3.7B speed controller controls the speed of three-phase motors and provides smooth start-up, eliminating the need for star-delta starters. It helps save energy and extend the motor’s service life, while protecting it against voltage fluctuations, short circuits and overloads.
The RS485 port supports automation applications and connection to a BMS for centralised motor control. It can work with temperature, humidity, pressure and CO2 sensors to automatically adjust speed and maintain stable operating conditions. It also features automatic restart after a power outage and remote control capability.
