Output Current vs. Altitude
Note
The ambient temperature is defined as the temperature 2 cm below the NI PS-16.
Protection Features
Output protection
Electronically protected against overload, no-load and short-circuits
Output over-voltage
protection
Typical 35 V
DC
Maximum 39 V
DC
In case of an internal power supply defect, a redundant
circuitry limits the maximum output voltage. The output
shuts down and automatically attempts to restart.
Output over-current
protection
Electronically limited
Refer to Figure A-10.
