Sorensen XEL series - advanced linear regulated laboratory power supplies
XEL Series: Analog control for a digital world

Linear regulation for ultra-low noise Lock your settings at the touch of a button !
Linear regulation still offers the lowest output noise and the best
transient response (recovery time from a sudden current step). Most
linear regulated power supplies offer low output noise with figures
below 2mV rms being typical. The XEL series goes a stage further with
an rms noise figure of 0.4mV with tightly specified pk-pk noise and
common-mode current figures.
Choose a voltage range that suits your task
When working with any particular piece of equipment, engineers often
require a voltage source variable over only a narrow range. Set the
voltage too high and damage might occur, set it too low and the circuit
may reset.
That's where the V-Span function of the New Sorensen XEL series comes
in. It allows the user to redefine the end-stop values of the voltage
control to define a specific voltage range.
For example:
An engineer is working on a circuit that will eventually operate from four
NiMh cells. They use V-Span to set a Vmax of 5.8 volts (to prevent
over-voltage damage) and a Vmin of 3.6 volts (to ensure that the
circuit doesn't reset).
They now have a power supply which provides high resolution analog
control over the exact voltage range they need.
Vmin and Vmax can be set anywhere between zero and maximum out-
put voltage subject only to Vmax > (Vmin + 0.1V). The fine control gives
additional adjustment of ±1%.
Once set, the voltage span function can be turned on or off at the press
of a button*.

* Safety interlocks
A key requirement in a power supply is to prevent the
wrong voltage or current being accidentally applied to the
circuit-under-test.
Consequently all operations that could result in an
unexpected change in voltage or current settings have
intelligent interlocks to prevent this.
** Safety terminals
The use of fixed-shroud 4mm plugs is becoming manda-
tory within an increasing number of laboratories for safety
reasons.
Standard binding post terminals can not accept these
fixed-shroud plugs.
Sorensen XEL-P Series - comprehensive remote control facilities
New XEL-P Series
Interface to every application
Bench and System use
The New Sorensen XEL-P series includes all of the manual control fea-
tures of the XEL series, but adds comprehensive remote control facilities.
The ultra-compact rack-modular sizing makes it ideally suited to rack
mounted system applications, while its user-friendly manual controls are
retained for bench top applications.
Rear Power Terminals
Power and sense terminals are duplicated on the rear panel for rack
mount applications or other situations where rear connection is more
appropriate.
Digital Remote Control
To meet the varying needs of today's engineers, a comprehensive array of
interfaces is provided. RS-232, USB and LAN (Ethernet) with LXI support
are provided as standard. An additional GPIB interface is also optionally
available.
Each of the digital bus interfaces provides full control of voltage, current,
and output on/off, plus read-back of voltage, current and status. The
interfaces are at ground potential and are opto-isolated from the output
terminals.
RS-232 IVI Driver
An RS-232/RS-423 interface is provided for use with legacy systems. An IVI driver for Windows is included. This provides support for common

Rack Mounting
Up to four single output units can be fitted into one rack width. Alter-
natively, any combination of singles and duals can be used - as in the
example shown. The rack mount kit (shown) is 4U high and incorporates
limited ventilation space above and below the power supplies. Blanking
