Features

Frequency inverter in comfort design with integrated, all-pole effective sine filter. For speed control of one or more fans. The permissible number of fans results from the maximum FU current. Includes display and three operating buttons for adjusting the fan and control parameters. Parameterization and control options via Modbus. With integrated, full control system for temperature, pressure and air speed. The required sensors LDF 500, LGF 10, LT .. are available as accessories. Speed specification via the 0-10 V control signal (e.g. potentiometer PU / PA, accessories). Integrated absolute humidity difference control, required sensors AFS 0-10V are available as accessories. Unlockable protection mode for use in safety-related systems, internal monitoring devices are bridged for the longest possible system operation. Over 10 m cable length between FU-CS and fan possible. No additional EMC shielding of the electrical lines required. The fans, including the motor, do not require any special EMC precautions for frequency inverter operation. When using the frequency converter with integrated sine filter, conventional standard fans / motors can be used.
