February 09, 2017 // By Graham Prophet
Distributor Luso Electronics has Qualstar’s N2Power branded XR125RE and XR125 AC-DC power supplies. These ultra-small power supplies claim the highest power density in the market at their rated 125W power output.

With an overall height of 1.25 inches and 3 x 5 inch (76.2 x 127mm) footprint, the XR125 series has a power density of 6.7 Watts per cubic inch, using an industry standard 1U chassis. Its small form factor is compatible with existing N2Power XL125 units. Achieving up to 91% peak efficiency, the XR160’s design requires minimal forced air-cooling and its reduced AC load improves economy of operation. The XR125RE has additional functionality with remote enable and a 5V standby (for a fixed load of 1A).
