Helios FU-CS 8

Frequency inverter in comfort version with integrated, all-pole effective sine filter for speed control of one or more fans. The permissible number of fans is determined by the maximum inverter current. Includes a display and three control buttons for setting fan and control parameters. Parameterization and control options via Modbus. Equipped with an integrated, fully functional control system for temperature, pressure, and air velocity. The required sensors LDF 500, LGF 10, LT are available as accessories. The speed setting is done via the 0-10 V control signal (e.g., potentiometer PU/PA, accessory). A cable length of over 10 m between the inverter and fan is possible. No additional EMC shielding of the electrical lines is required. The fans, including the motor, do not require special EMC precautions for inverter operation. When using the frequency inverter with integrated sine filter, conventional standard fans/motors can be employed.
