NATIONAL INSTRUMENTS NI PXI-1006 (01) PDF MANUAL

Key features of the power supply shuttle include the following:

• Universal AC input with automatic voltage and frequency ranging

• Over-current protection through push-reset circuit breaker

• Remote power monitoring and inhibit through a rear-panel connector

• Selectable fan speed

Carefully inspect the shipping container and the power supply shuttle for damage. Check for visible damage to the metal work. Check to make sure all handles, hardware, and switches are undamaged. Visually inspect the inside of the shuttle for any possible damage, debris, or detached components. If damage appears to have been caused during shipment, file a claim with the carrier. Retain the packing material for possible inspection and/or reshipment.

• NI PXI-1006 chassis (the unit being repaired)

• NI PXI-1006 power supply shuttle

• Read Me First: Safety and Radio-Frequency Interference

• NI PXI-1006 User Manual (provided with the chassis)

• No. 1 Phillips screwdriver

The components are:

1. Chassis Ground Screw

2. Universal AC Input

3. Circuit Breaker

4. Mounting Screws (10x)

5. Fan Speed Selector

6. Remote Power Status and Inhibit Connector

Caution: Many components within the PXI-1006 chassis under repair are susceptible to static discharge damage. Service the chassis only in a static-free environment. Observe standard handling precautions for static-sensitive devices while servicing the chassis. Always wear a grounded wrist strap, or equivalent, while servicing the chassis.

Caution: Always disconnect the AC power cable before cleaning or servicing the chassis.

Caution: Never connect the AC power cable to the power supply shuttle until you install it in a PXI-1006 chassis. Do not use, test, or configure the power supply shuttle outside of a chassis.

Before attempting to replace the power supply shuttle, verify that there is adequate clearance behind the chassis. Set the power switch on the front panel to the Standby position and disconnect the power cable from the power supply shuttle on the back of the chassis. Identify the ten mounting screws that attach the power supply shuttle to the chassis. Using a Phillips screwdriver, loosen the captive screws. Pull on the two rear handles of the power supply shuttle to remove it from the back of the chassis.

Ensure that there is no visible damage to the new power supply shuttle. Verify that the housing and connector on the new power supply shuttle have no foreign material inside. Install the new power supply shuttle into the opening on the rear of the chassis. Tighten the ten mounting screws with a Phillips screwdriver.

The fan-speed selector switch is on the rear panel of the power supply shuttle. Select HI for maximum cooling performance (recommended) or AUTO for quieter operation.

Caution: The power supply shuttle is designed with a three-position NEMA 5-15 jack that connects the ground line to the chassis ground. To minimize shock hazard, make sure the electrical power outlet you use to power the chassis has an appropriate earth safety ground.

If your power outlet does not have an appropriate ground connection, you must connect the premise safety ground to the chassis ground screw. Complete the following steps to connect the safety ground.

1. Connect a 16 AWG (1.3 mm) wire to the chassis ground screw using a grounding lug. The wire must have green insulation with a yellow stripe or must be noninsulated (bare).

2. Attach the opposite end of the wire to permanent earth ground using toothed washers or a toothed lug.

Input voltage range: 90 to 264 VAC

Input frequency range: 47 to 63 Hz

Maximum steady state operating current: 10 A

Over-current protection: 10 A circuit breaker

Line regulation: ±0.1% over operating line range

Efficiency: 70–80% typical

Power disconnect: The Off (standby) power switch causes the power module to supply DC power to the CompactPCI/PXI backplane. The rear-panel D-sub connector facilitates remote inhibiting operation. The Off (standby) switch must be in the On position prior to use of remote inhibit. The power cord provides main power disconnect.

Maximum usable power: 600 W

DC current capacity (IMP)

Load regulation

Maximum ripple and noise: 1% ripple, 1% noise, 20 MHz bandwidth

Over-current protection: 105–140% of rated output current; automatic recovery

Over-voltage protection: 3.3 V, 5 V clamp at 122–134% of output voltage; +12 V and -12 V clamp at 110–120% of output voltage
