300 Watts with Linear Performance HPD 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.
