DIN rail mounted speed controller for three phase motors
TVSS5 series are electronic fan speed controllers with analogue input. The TK monitoring function protects motors against overheating. Their enclosure allows DIN rail mounting. They control three-phase voltage controllable motors with a maximum current of 6 A. The fan speed is regulated by varying the motor voltage via phase angle control - Triac technology. The minimum and maximum speed is adjustable via trimmers. The motor volltage 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.
