With up to 540 watts of programmable DC power in a quarter-rack wide chassis, the Sorensen XPD is the highest power density product available in its power range. Choose from five models for benchtop and OEM applications, where a wide adjustment of output voltage or current is required in a compact package.

The Sorensen XPD utilizes state–of–the–art zero voltage or "soft" switching technology to virtually eliminate switching transients for high efficiency, low noise and high reliability. It is also power factor corrected for low current draw and reduced generation of input current harmonics. For systems applications, XPD can be rack mounted in multiple-unit configurations of up to four independent 500 watt outputs. For example, XPD can be combined with other Xantrex programmable DC power supplies such as the quarter­rack 300 watt HPD and the 60 watt XT.
