The hatronic frequency inverter DC-FI from Hanning can be used wherever there is a demand for powerful, dynamic and intelligent drives with positioning functions. With a switching frequency of 16 kHz, the frequency inverter operates in the inaudible range. A customized layout as well as individual equipment variations and designs make the compact low voltage inverter into a highly flexible all-rounder. Adapted to specific application requirements, the variable speed drive system with the frequency inverter regulates constantly hamatic linear actuators and hamatic lift columns with low voltage three-phase winding. All processes and lifting movements, e.g. in medical applications, are implemented smoothly and silently with precise positioning. The compact inverter is used, for instance, in therapy couches, treatment chairs and operating tables with outputs of up to 750 W and input voltage of 36 to 42 V DC. The frequency inverter is freely programmable and individually controllable - either by analog or a CAN bus system. Its configuration also includes a soft start in addition to a wide variety of other functions.
