Helios FU-C 4.2

Frequency inverter in comfort version without sine filter for controlling the speed of a single fan. It features a display and three control buttons for setting the fan and control parameters. Parameterization and control options are available via Modbus. The device offers an integrated, fully functional control system for temperature, pressure, and air speed. The required sensors LDF 500, LGF 10, LT... are available as accessories. The speed is adjusted via the 0-10 V control signal (e.g., potentiometer PU/PA, accessories) or by direct input on the display. The maximum cable length between the frequency inverter and the fan is 10 m with shielded cable. The fan must be designed for operation with a frequency inverter (EMC-compliant fan/motor, possibly special version). For operation without a sine filter, the suitability of the frequency inverter must be specified when ordering the fan.
