AC fan speed controller for single phase motors with TK

EVSS1 series are electronic fan speed controllers with analogue input. The TK monitoring function deactivates the motor in case of overheating. They regulate the speed of single-phase voltage controllable motors with a maximum current of 10 A. The AC fan speed is controlled by varying the motor voltage via phase angle control - Triac technology. The minimum and maximum speed is adjustable via trimmers. The motor voltage can be regulated via the analogue input or via Modbus RTU. Kick start or soft start acceleration and the operating mode is selectable via Modbus RTU. A remote start/stop command can be generated via the digital input.
