NI PS-13 Input Voltage Vs. Output Load
Input Current Inrush Surge
An active inrush limitation circuit limits the input inrush current after input voltage is applied.
The charging current into EMI suppression capacitors is disregarded in the first milliseconds
after power up.
Note
Input current values are typical with Ta = 25 °C, cold start.
