Communications and Control Unit (CCU)

Our innovation for 2015 – the CCU box

The Communications and Control Unit (CCU) can communicate via all common media such as Bluetooth, ZigBee, GSM, Wireless LAN, RS 232, RS 485 and Ethernet, which enables it to control and monitor external devices.
The box can be used just as effectively in "smart homes" as in the field of eMobility, which has opened up undreamed-of possibilities, and not just when it comes to renewable energies.
