3.6. I/O Power Output
Specification of the +12 V power output of the I/O connector
A non-isolated +12 V power output is available on every I/O connector.
The power originates from an external 12 V power supply plugged into the Auxiliary Power Input
connector. It is distributed from a common electronic fuse to all the I/O connectors.
The electronic fuse provides the following protections:
● Limits the inrush current during power on sequence
● Protects the Coaxlink card and the power source against overload
● Protects the Coaxlink card the power source against short-circuits.
The sum of the load currents drawn from all the 12 V outputs of the I/O connectors must be
lower or equal to the specified maximum output current.

NOTE
The above specification applies over the whole operating temperature range
of the Coaxlink card.
