Overview: Programmable linear DC power in a quarter-rack package

  • Overview +


    Sorensen XT Series
    The Sorensen XT provides 60 watts of programmable linear DC power in a quarter-rack package. With seven models to choose from, XT is the smart choice for both benchtop and system applications where up to 60 watts of programmable, clean DC power is required. XT is also ideal for OEM applications where a wide adjustment of output voltage or current is required for up to 60 watts in a compact package.

    The Sorensen XT is a preferred source for system development and test. It is available in singles, duals, triples and quads in a single package for benchtop use. For systems applications, multiple units can also be rack mounted in one to four unit configurations for up to four independent 60–watt outputs. XT can also be combined in a rack with the 300–watt HPD or 500–watt XPD.

    1. Specifications indicate typical performance at 25° C ± 5°C, nominal line input of 115 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 30-minute warm-up.
    5. Change in output per °C change in ambient temperature, with constant line and load.
    6. Apply accuracy specifications according to the following voltage program accuracy example: Set a model 15-4 power supply to 10 V. The expected result will be within the range of 10 V ± 20 mV ± 0.1% of the set voltage of 10 V.
