250 W 1U server power supply

The Enhance ENP-7025B is a proprietary FlexATX unit built for 1U rack-mount servers, industrial panel PCs and kiosks. It accepts 100 to 240 VAC input at 47 to 63 Hz and carries 80 Plus and RoHS certification. The compact form factor fits space-constrained enclosures where standard ATX units cannot be used.

+12 V dual-rail output

Each +12 V rail delivers up to 18 A while the combined 3.3 V and 5 V rails must not exceed 80 W. This split-rail layout is the single specification that determines whether the unit can power the installed processor and drive complement. Verify the platform's rail requirements before installation.

Continuous load behaviour

At full rated output the supply maintains a 16 ms hold-up time and is rated for 100 000 hours MTBF. A single 40 mm fan provides active cooling inside the 1.6 inch high chassis. The design targets sustained operation in always-on server and kiosk deployments rather than short peak bursts.
