The B&K Precision XLN series are programmable,
single-output DC power supplies, that provide
clean power up to 1560 watts in a compact 1U
rackmountable package. Comparable supplies
from other manufacturers primarily address the
ATE market only, while the XLN series is designed
for both benchtop users and system integrators.
For benchtop applications, these power supplies
offer built-in voltage and current meters
displaying setting and output values concurrently,
as well as an intuitive user interface with full
keypad and rotary knob.

function
■Easy to configure master/slave mode for series
or parallel connection of up to four units
Standard USB, RS485, and optional GPIB and
LAN interfaces combined with fast average
command processing times of less than 50 ms
make the XLN series ideal for ATE applications.
Free application software and a complete set of
LabVIEW™ drivers are available to provide
remote control capabilities, reduce programming
time, and increase productivity.
When greater output power is required, up to
four XLN models can be connected in series
(high current models only) or parallel and
synchronized with the RS485 interface.
Alternatively, the RS485 interface can be used
to daisy chain up to 31 units and to remotely
control them from one master PC via USB, GPIB,
or LAN interface.
These power supplies are perfectly suited for
ATE systems integration, product design and
development, product QC and burn-in testing,
and other applications requiring excellent
regulation, high power, low noise, and a wide
range of voltage and current ratings.

Interfaces
Front panel operation
The numeric keys and rotary knob provide a convenient interface for setting output levels quickly and precisely. Both measured output values and setting values are
concurrently displayed on the screen. Additionally, the power supplies provide internal memory for storage of up to 10 different instrument settings that can be set
and recalled via both the front panel and remote interfaces.

Flexible configuration
Up to four models with the same rating can be
connected in parallel or series (high current
models only) and operate in master/slave mode.
The RS485 interface is used for communication
between the master and slave(s). Once configured,
the master will automatically search for and detect
slave units, and display the voltage and current of
the complete system.
To protect your DUT, the XLN series provides
more safety features than any other system power
supply in this category: overvoltage (OVP),
overcurrent (OCP), overpower (OPP), and
overtemperature (OTP) protection. When a fault
occurs, the power supply will turn off the output,
sound an alarm, and display an error message.
Similarly, with constant voltage-to-constant current
(CV-to-CC) or constant current-to-constant
voltage (CC-to-CV) foldback protection mode
activated, the supply will shut down if load changes
force the supply to transition between the two
operating modes. The power supply is also able
to detect abnormally low AC input power and
turn the output off when this condition occurs.
The remote sense feature can compensate for
voltage drop in the load wiring.
Convenient front panel guided
calibration
Using a 5 ½ digit multimeter and a current
shunt, voltage and current parameters can be
conveniently calibrated from the front panel via
the calibration menu.

(high current models only)
Master/Slave operation Extensive device protection
Remote sense
The high current XLN models offer an additional
output with a constant output voltage of 5 V and
a maximum output current of 1 A for powering
another device.
Fixed 5V/1A output (high current
models only)
Power Line
The XLN series can be used to accurately
measure the time for a fuse or circuit breaker to
open. After the voltage and current levels are
set, the On/Off button turns on the output
and the time when the fuse/breaker opens is
measured to the nearest 100 µs. The maximum
counting period is one hour.

Remote access and programming
These power supplies offer standard USB
along with optional GPIB and LAN interfaces
to facilitate test system development and
integration. The XLN series supports SCPI
IEEE488.2 and come with LabVIEW™ drivers.
System integration
The power supply can be controlled with SCPI
commands via a Telnet connection over the
Ethernet interface. Any computer with a Telnet
client can be used to control the power supply.
Telnet interface
PC software is provided for creating and executing
test sequences in list mode via the USB or GPIB
interface.
Generate, save, and load program lists. View
output characteristic curves and export data to a file.
Pass/Fail test monitors maximum and minimum voltage
and current values over a specified period of time.
Application software
XLN series models with GPIB and LAN interfaces
provide a built-in web server that allows users to
configure, control, or monitor the basic settings
of the power supply from a remote computer
using a web browser.
Web server interface
The list mode feature allows users to download a
list of commands to the power supply’s internal
memory and execute them. Up to 10 sets of
programs can be stored with a total of 150 steps
allocated among the memory locations. The test
sequence can be programmed remotely via the
USB, GPIB, or LAN interfaces using SCPI
commands or the included application software.
Each step’s voltage, current, and duration
parameters can be set, with sequences
configured for single or repeated execution.
Test sequence execution in list mode
In addition to front panel or remote interface
control, voltage and current values can also be
programmed with an analog control signal. The
power supplies can be externally controlled from
zero to full scale by either an analog voltage
source (0-5 V/0-10 V selectable) or resistance
(0-5 kΩ, 0-5 kΩ/0-10 kΩ selectable for high
voltage models). High voltage models also
provide additional functions to the analog
programming interface such as the ability to
monitor the output voltage and current, check
regulation mode (CC or CV), and indicate
whether a fault has occurred.
External analog programming
interface
Interface for controlling voltage, current,
and output state.
In multi-unit control mode, up to 31 units can be
daisy chained via RS485 and controlled from one
master unit through the USB, GPIB, or LAN
interface.
