1. Helios FU-CS 2.5
Frequency converter in Comfort version with integrated, fully effective all-pole sine filter for speed control of one or more fans. The permissible number of fans is determined by the maximum frequency converter current. Includes a display and three control buttons for setting fan and control parameters. Parameterization and control options via Modbus. 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, accessories). A cable length of over 10 m between the frequency converter and fan is possible. No additional EMC shielding of the electrical lines is required. The fans, including the motor, do not need special EMC precautions for frequency converter operation. When using the frequency converter with an integrated sine filter, conventional standard fans and motors can be used.
2. Helios FU-BS 2.5
Frequency inverter in basic design 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. The speed setting is done via the 0-10 V control signal (e.g., potentiometer PU/PA, accessories). 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 need special EMC precautions for frequency inverter operation. The inverter is fixedly set to its rated current. When using the frequency inverter with integrated sine filter, conventional standard fans/motors can be used.
3. Helios FU-B 5.0
Frequency inverter in basic version without sinus filter for speed control of a single fan. The speed setting is done via the 0-10 V control signal (e.g., potentiometer PU/PA, accessories). The maximum cable length between the 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). The frequency inverter is permanently set to its rated current. For inverter operation, the suitability for frequency inverter must be specified when ordering the fan.
