Sorensen HPD Series
300 W
300 Watt DC Power Supply with Near-Linear Performance
• Low noise and ripple
• Excellent line/load regulation
• Constant voltage or constant current operation
with automatic crossover and mode indication
• Current limit
• Front and rear outputs
• Remote sense
• LabVIEW® and LabWindows® drivers
The Sorensen High Power Density (HPD) Series
provides 300 watts of reliable DC power in a
quarter-rack wide unit. The HPD Series power
supplies are ideal for benchtop, ATE and OEM
applications where a wide adjustment of output
voltage or current is required in a compact unit.
The HPD series uses switch-mode technology
combined with linear post regulation to provide
performance comparable to an all-linear design.
The HPD series features excellent line and load
regulation with low noise and good transient
response. The series is available in a single unit for
benchtop use. For systems applications, multiple
units can be rack-mounted in congurations of
up to four independent 300-watt outputs.

Specications subject to change without notice.
1. Specications indicate typical performance at 25°C ± 5°C, nominal line input of 120 Vac.
2. For input voltage variation over the AC input voltage range, with constant rated load.
3. For 0-100% load variation, with constant nominal line voltage.
4. Maximum drift over 8 hours with constant line, load, and temperature, after 60-minute warm-up.
5. Change in output per °C change in ambient temperature, with constant line and load.
6. Apply accuracy specications according to the following voltage program accuracy example: Set a model 15-20 power supply to 10 V. The expected result will be within the
range of 10 V ± 60 mV ± 0.1% of the set voltage of 10 V.
