The Airtechnic 500 4T1.1B speed controller controls the speed of three-phase motors and provides a smooth start, eliminating the need for star-delta starters. Speed can be controlled automatically using temperature, humidity, pressure or CO2 sensors, or via step control.
The RS485 port allows connection to a BMS for centralised motor control and automation applications, such as switching a gas supply solenoid valve on and off. Remote control is also supported via a detachable display or a switch and potentiometer. The controller protects the motor against voltage fluctuations, short circuits and overloads, and restarts automatically after a power outage.
