The Enedo/Efore/Roal 231A is a high-power density, multi-output Switched-Mode Power Supply engineered for demanding industrial and commercial applications. This SMPS integrates directly into PXI and PXI Express chassis architectures, delivering up to 700 W of available power across multiple voltage rails. Its compact design enables integration into systems requiring efficient power conversion with minimal footprint, while supporting external remote power-inhibit control for system-level power management.
## Technical Specifications
• **Power Output:** Up to 700 W available power
• **Form Factor:** PXI and PXI Express compatible; also supports CompactPCI and CompactPCI Express integration
• **Multi-Output Configuration:** Supplies multiple voltage levels to diverse system components
• **Operating Temperature:** 0 to 55 °C
• **Cooling:** Convection cooling with variable speed fan controller
• **Acoustic Emissions:** Low-noise operation; fan controller optimizes thermal and acoustic performance
## Key Features
• High power density maximizes output capacity in compact chassis footprint
• Multi-output topology supports mixed-voltage system architectures
• Remote power-inhibit control enables external on/off switching
• Variable speed fan management balances thermal control and acoustic signature
• Integrated design for direct chassis deployment without external enclosures
## Typical Applications
• Multi-module PXI/PXIe test and measurement systems
• Industrial instrumentation requiring distributed DC power rails
• Commercial equipment demanding high current capacity in confined spaces
• Systems with stringent thermal management requirements
## Compatibility & Integration
The 231A integrates into PXI, PXI Express, CompactPCI, and CompactPCI Express chassis. Compatible systems include the National Instruments PXIe-1065, which provides multiple peripheral and Express slot configurations. The associated chassis delivers over 3 GB/s total system bandwidth and up to 1 GB/s per-slot dedicated bandwidth for PXIe modules, with internal reference clocks at 10 MHz (PXI) and 100 MHz (PXIe Express) maintaining 25 ppm stability.
