The Sorensen HPD Series provides 300 watts in a quarter–rack wide chassis. It is ideal for OEM applications where wide adjustment of output voltage or current is required in a compact package, providing up to 300 watts of clean power. HPD is available in three models and is the smallest 300–watt programmable power supply available.HPD uses switch–mode technology combined with linear post regulation to provide performance comparable to an all–linear design. Excellent line and load regulation is matched by low noise and good transient response. HPD is available in singles and duals in a single package for benchtop use. It can be combined in mix and match rack combinations with the quarter–rack 60 watt XT or 500 watt XPD. For systems applications, multiple units can be rack mounted in one to four unit configurations for up to four independent 300–watt outputs.
