Din-Rail 48 V Server Supply

This Black Box Corporation SDR-240-48 is a new 240 W server power supply that delivers 48 Vdc from a 120 V AC or 230 V AC input. It carries TÜV Rheinland energy-efficient certification and operates at 90.5% efficiency. The unit is built for din-rail mounting inside industrial cabinets and telecom racks.

Suited for fixed 48 Vdc loads, not for ATX PCs

Installers powering PLCs, industrial sensors or telecom gear that require a steady 48 Vdc rail will find the voltage and power rating match common control-panel needs. Builders assembling standard desktop or server computers should look elsewhere because the output voltage and form factor do not match ATX or EPS specifications.

48 Vdc output voltage decides fit

The single specification that determines compatibility is the 48 Vdc output; the connected equipment must be rated for that exact voltage. If the load requires 12 V, 24 V or any other potential, this supply cannot be used.

Questions about this item

What does the 240 W maximum power mean for a server running this supply?

It delivers up to 240 W at 48 Vdc, so the connected server components must draw no more than that total under full load.

How does the 90.5 % efficiency and TÜV Rheinland certification affect daily operation?

The unit converts AC input to 48 Vdc at 90.5 % efficiency, and TÜV Rheinland confirmation means it meets recognised energy-efficiency requirements.

What mounting method does this power supply use?

It is a DIN rail power supply designed to clip onto standard DIN rails inside a cabinet or enclosure.
