DC power supply

The Sorensen series XEL-P DC linear power supplies are suitable for bench work as well ATE tasks. The supplies are characterised by low ripple (0.4 mV RMS) and lockable analog controls.

Control ports include RS232, USB and ethernet LAN and an optional GPIB interface. The ethernet interface is LXI (LAN extension for instrumentation) compliant. In addition, analog control (0-10 VDC) for current and voltage setting is provided as standard.

The supplies are 3U modules that can be assembled in 12U cabinets. Models are available as single output and dual output (6U) in ratings of 0 to 15 V (0-5 A), 0 to 30 V (0-3 A), 0 to 60 V (0-1.5 A) single output and in dual output versions of 0 to 30 V (0-6 A when paralleled).

The supplies have features including the so-called ’V-Span’ function which permits an engineer to set arbitrary (within 0 to max rated voltage) upper and lower limits of voltage, covering the entire range of the analog knob rotation control; the lockable voltage and current settings; and for dual output models, three operational modes (independent, true parallel and tracking modes).

In the independent mode, the two outputs are electrically isolated from one another and independently adjustable. In the isolated tracking mode, the outputs are still electrically isolated but have identical values.

In the ratio-tracking mode, one output voltage can be set as a percentage ratio of the other, while remaining electrically isolated.
