Communication module (for the switched-mode modular system HFS)

intelligent solution with no compromises !

kom modul


Modular systems HFS consist of the following parts:

  • up to 3 power modules HFM-A
  • common control unit (module)
  • optional communication module

For a complete remote control and administration of the HFS systems we offer an optional communication module (stand-alone or integrated within a HFS rack). It is linked-up with the HFS control unit by the optical interface up to a distance of tens of meters.

Its main part is a touch-sensitive display. There are all the functions and setups accessible in the menu system. It is possible to control up to 4 HFS systems.

The second main feature of the communication module is that in case of a failure of one of the administered systems it automatically calls a remote service center using either an analog telephone line (modem), mobile line (GSM modem) or a LAN/Internet (TCP/IP adaptor) and sends an alarm message directly to the system operator.
