The National Instruments PXI-1042 Series Power Supply Shuttle User Guide provides installation, configuration, safety, and specification details.
This user guide explains how to unpack, install, and maintain the NI PXI-1042 Series Power Supply Shuttle, a replacement part for the PXI‑1042 chassis. It describes key features such as universal AC input, over‑current protection, remote monitoring, temperature‑sensing fan control, and a front‑panel LED indicator.
The document also covers safety precautions, grounding requirements, compliance with IEC, UL, and FCC standards, and provides detailed electrical specifications for AC input, DC outputs, efficiency, and protection features.
| AC Input voltage range | 100 to 240 VAC |
|---|---|
| Input frequency | 50/60 Hz |
| Input current rating | 8 A |
| Over‑current protection | 10 A circuit breaker |
| Efficiency | 70 % typical |
| +3.3 V DC output current | 20 A |
| Load regulation | <5 % (for +3.3 V, +5 V, +12 V, –12 V) |
First disconnect the AC power cable and set the front‑panel power switch to Off, then loosen the eight captive mounting screws, pull the rear handles to remove the old shuttle, place the new shuttle in the opening, and tighten the screws with a Phillips screwdriver.
Service the chassis in a static‑free environment, wear a grounded wrist strap, and always disconnect the AC power cable before cleaning or servicing the chassis.
The rear‑panel fan‑speed selector switch can be set to HIGH for maximum cooling or AUTO for quieter operation, where the intake temperature automatically adjusts the fan speed.
The shuttle accepts a universal AC input of 100 to 240 VAC, 50/60 Hz, with an input current rating of 8 A and over‑current protection via a 10 A circuit breaker.
