Introduction
Unmatched Precision, Unrivalled Performance
The XDL series represents the ‘next generation’ of laboratory power supplies offering an
unparalleled level of precision.
Voltage and current are controlled using 16 bit DACs enabling voltages to be set to 1mV
resolution even at full output. Indeed, the accuracy is sufficient for the PSU to be used as a
calibration source for most hand-held DMMs.
The XDL series uses pure linear technology and offers unrivalled performance in terms of
regulation, output noise and dynamics. Line and load regulation are at the limit of measurement
(nominally 0·002%). Output noise is less than 500µV rms. Recovery time from transient current
pulses is better than 50µs.
The XDL series provides full remote sense capability via dedicated sense terminals. Remote
sense is essential to maintain precise regulation at the load (two 0·03Ωconnection leads will drop
300mV at 5 Amps). When remote sense is not required, internal local sensing can be selected at
the touch of a button.
Multiple Ranges for Greater Flexibility
The XDL series provides multiple ranges for increased current capability at lower voltages. The
main range offers 0 to 35 Volts at up to 3 Amps (XDL 35-5) or 0-56V at up to 2 Amps (XDL 56-4).
The higher current range provides up to 5 Amps for voltages up to 15V (XDL 35-5) or 4 Amps for
voltages up to 25V (XDL 56-4). A further low current range provides enhanced current setting and
measurement resolution of 0·1mA.
The product of voltage and current can be displayed at any time by pressing the VxA button. The
power is displayed to a resolution of 0·01 Watts.
Fast, Simple and Safe to use
The user interface of the XDL series has been carefully designed to provide rapid control whilst
guarding against any possibility of error.
Voltage and current setting can be performed either by direct numeric entry or, for applications
where the voltage or current must be gradually changed, by using the quasi-analogue Jog
control.
To enable the current limit to be set before connecting the load, the limit setting is displayed when
the output is off. Pressing the View Limits key at any time provides a temporary display of the limit
values allowing precise adjustment to also be made with the output on.
Setting Memories for Added Convenience
The XDL series provided storage of up to 10 power supply sets-ups in non-volatile memory. Upon
mains switch-off, the set-up of the PSU is saved and is automatically restored at switch-on.
OVP and OCP Trips with 'Alarm' Output
The XDL series provides fully adjustable over-voltage and over-current trips which can be used
both as a fail-safe against accidental mis-setting and as a protection against inappropriate load
conditions. In addition to turning the output off, a trip condition switches the rear panel alarm
signal enabling other equipment to be controlled.
For complete protection of the power supply, the trip will also be operated by over-temperature or
excess voltage on the sense terminals.

Fully Programmable via GPIB, RS232 or USB
The XDL 35-5P and XDL 56-4P incorporate a full bus interface permitting remote control and
readback via either GPIB (IEEE-488), RS232 or USB.
The GPIB interface conforms fully with IEEE-488.2 and IEEE-488.1.
The serial interface can be used as a conventional RS232 interface or as part of a multi-
instrument addressable RS232 chain.
USB represents the future for medium speed PC connectivity. By adding USB hubs, multiple
devices can be connected. A Windows device driver is supplied which creates a virtual COM
port, enabling USB to be used with applications that do not directly support it.
XDL series supplies use simple and consistent command structures which make programming
particularly easy regardless of which interface is used.
A National Instruments LabWindows* device driver is available.
All power supply settings can be controlled via the bus. Voltage and current can be set to a
resolution of 1mV or 0·1mA. Actual voltage and current can be read back together with the power
supply status.

EMC
This instrument has been designed to meet the requirements of the EMC Directive 2004/108/EC.
Compliance was demonstrated by meeting the test limits of the following standards:
Emissions
EN61326 (1998) EMC product standard for Electrical Equipment for Measurement, Control and
Laboratory Use. Test limits used were:
a) Radiated: Class B
b) Conducted: Class B
c) Harmonics: EN61000-3-2 (2000) Class A; the instrument is Class A by product category.
Immunity
EN61326 (1998) EMC product standard for Electrical Equipment for Measurement, Control and
Laboratory Use.
Test methods, limits and performance achieved were:
a) EN61000-4-2 (1995) Electrostatic Discharge : 4kV air, 4kV contact, Performance A.
b) EN61000-4-3 (1997) Electromagnetic Field, 3V/m, 80% AM at 1kHz, Performance A.
c) EN61000-4-11 (1994) Voltage Interrupt, 1 cycle, 100%, Performance B.
d) EN61000-4-4 (1995) Fast Transient, 1kV peak (AC line), 0·5kV peak (DC Outputs),
Performance B.
e) EN61000-4-5 (1995) Surge, 0·5kV (line to line), 1kV (line to ground), Performance B.
f) EN61000-4-6 (1996) Conducted RF, 3V, 80% AM at 1kHz (AC line only; DC Output
connections <3m not tested), Performance A.
According to EN61326 the definitions of performance criteria are:
Performance criterion A: ‘During test normal performance within the specification limits.’
Performance criterion B: ‘During test, temporary degradation, or loss of function or
performance which is self-recovering’.
Performance criterion C: ‘During test, temporary degradation, or loss of function or
performance which requires operator intervention or system reset occurs.’
Where Performance B is stated it is because DC Output regulation may deviate beyond
Specification limits under the test conditions. However, the possible deviations are still small and
unlikely to be a problem in practice.
Note that if operation in a high RF field is unavoidable it is good practice to connect the PSU to
the target system using screened leads which have been passed (together) through an absorbing
ferrite sleeve fitted close to the PSU terminals.
Cautions
To ensure continued compliance with the EMC directive observe the following precautions:
a) after opening the case for any reason ensure that all signal and ground connections are
remade correctly and that case screws are correctly refitted and tightened.
b) In the event of part replacement becoming necessary, only use components of an identical
type, see the Service Manual.
