I/O Power Output
Specification of the +12V 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.
Parameter | Conditions | Min. | Typ. | Max. | Units |
---|---|---|---|---|---|
Aggregated output current | Operating temperature range | 1.0 | A | ||
Voltage drop across the electronic fuse | Max. output current | 0.2 | V |
Note: The above specification applies over the whole operating temperature range of the Coaxlink card.
