NI 188802-01 Power Supply

The NI 188802-01 is a removable, high-performance AC power supply designed for integration within National Instruments PXI chassis systems. This 500W maximum output unit provides stable, regulated power to internal PXI and CompactPCI modules in 3U rackmount configurations. With universal input voltage acceptance and an auto/high fan selector for thermal management across extended operating temperatures, the power supply delivers the reliable performance required in modular test and measurement systems while supporting reduced mean time to repair through its modular architecture.

– Technical Specifications

• Maximum Output Power: 500W
• Input Voltage Range: 100-240 VAC
• Operating Temperature Range: 0 to 55 °C
• Form Factor: 3U PXI and CompactPCI module compatibility
• Weight: Approximately 10 lbs per unit

– Key Features

• Auto/High Fan Selector for adaptive cooling
• Removable design enabling straightforward maintenance and module replacement
• Accepts 3U PXI and CompactPCI modules

– Typical Applications

The NI 188802-01 primary application is powering National Instruments PXI-1042 Series 8-Slot 3U PXI Chassis systems. The modular power supply architecture supports high-performance test, measurement, and control applications where reliability and serviceability are critical.

– Compatibility & Integration

Designed specifically for the PXI-1042 Series chassis, this power supply integrates internally without user-accessible external interfaces. The unit functions solely to supply power to internal PXI and CompactPCI modules. Alternative manufacturer equivalents exist through Autec Power Systems: MFS50-EGLW-1574 (for NI variants 188802A-01 and 188802B-01) and MFS50-EGLW-1642 (for NI variant 188802C-01).
