The Sorensen XEL linear benchtop power supply is as easy to use as simple analog power supplies but offers the flexibility of advanced digital features. The user interface allows easy control with single-turn knobs including a fine control knob for voltage. 

This easy-to-use interface is complemented by V-Span, S-lock, and Output Enable functions. 

V-Span allows the user to set a maximum and minimum value over which the knob control operates. This provides more precise control over the voltage as the knob operates over a narrow range as well as protecting devices under test by limiting the maximum voltage. 

S-Lock provides an easy method to output a regulated fixed voltage. 

Output Enable lets the user set up the desired voltage and current levels prior to turning on the output. All these features in a laboratory bench supply are only found in the XEL series linear benchtop power supply. 

The programming "P" models include LXI Class C Ethernet, USB, RS-232, and analog remote control. The option "GP" includes GPIB programming plus all the interface methods included with the "P" models described above. This remote programming capability makes the XEL-P models well-suited for system or ATE integration. 

At 4.2x11.3 inches (108mm x 287mm), the XEL series occupies the least benchtop space of any programmable DC power supply. The dual output model offers 90W per channel, also in a compact 8.4x11.3 inches (216mm x 287mm). 

The dual output XEL30-3D is two 30V/3A power supplies in one unit. All the features of the single output version are also in the dual output. The outputs are fully independent and isolated. Plus, the outputs can be operated in 4 modes: isolated, tracking, ratio tracking, and true parallel. In addition, the outputs can be enabled (on/off) independently or synchronously.
