The CX2500-0070 devices extend the CX20x0 system with four further USB 3.0 interfaces. Each interface
has a maximum power output of 900 mA. The maximum total power output is 2000 mA. The interfaces are
backward compatible with the USB 2.0 and USB 1.1 standards.

Maximum current output
The maximum total current over all four USB interfaces is 2000 mA. If this value is exceeded, the
whole module (i.e. all interfaces) is switched off. Once the overload situation is resolved (i.e. once
the consumer that caused the overload has been removed), the module restarts, and the other de-
vices are once again available.
