Single-Rail 48 V Server Supply

This 450 W enclosed switching power supply delivers 48 VDC at 9.5 A from a universal 85 VAC to 264 VAC input. Active PFC achieves a power factor above 0.95 and 89.5 % efficiency. A 5 V standby rail provides 0.3 A for management functions. Built-in protections cover short circuit, overload, over-voltage and over-temperature conditions.

Desktop Chassis Integration

The 8.6" x 4.1" x 1.6" form factor fits desktop server chassis where a single high-current 48 V rail is required. Remote on-off and DC-OK signalling simplify rack-level control. The screw-terminal output block and fan on-off control suit embedded or industrial builds. Systems needing multiple voltage rails or redundant hot-swap modules should evaluate other form factors.

48 VDC 9.5 A Output Rating

The decisive specification is the single 48 VDC output rated at 9.5 A continuous current. Verify that the target platform accepts this voltage and current level before purchase.

Questions about this item

How can I confirm the power supply is operating correctly after installation?

Verify the DC OK signal is present and measure 48 VDC at the screw terminal block under load; the built-in 5 V standby rail should also read 5 V at 0.3 A when the main output is active.

What comes in the box and what must be sourced separately?

The unit includes the enclosed 450 W power supply with integrated cooling fan and screw terminal block for output wiring; AC input cable, mounting screws and any additional DC distribution connectors are not included.

Which capacity should I choose for a 48 V server chassis build?

This model delivers 48 V at 9.5 A for 456 W maximum; select it when your total 48 V load stays below 9.5 A — otherwise a higher-current 48 V unit is required.
