Enedo / Efore / Roal 231A High Power Density Multi Output SMPS

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.
