1.44 kW Programmable DC Power Supplies
XLN Series
New Family of High Density System
Power Supplies
The B&K Precision XLN series are compact,
programmable, single-output DC power supplies,
suitable for a wide range of applications. Comparable
supplies from other manufacturers primarily address
the ATE market, while the XLN series are designed
for both bench top users and system integrators.
For bench top 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. Free
application software is available to provide remote
control capabilities without the need for any computer
programming. Standard USB & RS485 and optional
GPIB & LAN interfaces combined with fast average
command processing times of less than 50 ms make
the XLN series ideal for ATE applications. A complete
set of LabVIEW™ drivers are also available to reduce
programming time and increase productivity.
The XLN series provide clean power up to 1440
watts, with very low ripple and noise, in a compact
1U high 19 inch wide package. The supplies are
perfectly suited for ATE systems integration, product
design and development, product QC and burn-in
testing, production, electro-plating and other
applications requiring high power and a wide range of
current and voltage ratings. When greater output
power is required, up to four XLN models can be
connected in either series or parallel and be
synchronized with the RS-485 interface. Alternatively,
the RS-485 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.
To protect your device(s) under test, the XLN series
provide comprehensive safety options such as OVP,
OCP, OPP, CV and CC protection as well as low input
voltage protection. The supplies are designed to last
and are backed by a two year warranty.

The numeric keys and rotary knob provide a
convenient interface for setting output levels
quickly and precisely. Voltage and current can be
set to a maximum resolution of 1 mV and 1 mA,
respectively. Both meter values (measured output
values) and setting values are concurrently
displayed on the screen. Additionally, the power
supplies provide a memory space for storage of 10
instrument settings that can be set and recalled via
both the front panel and remote interfaces.

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.
The output voltage and current can be controlled
by either analog voltages or resistances. 0-10 V
voltages and 0-5 kΩ resistances control from zero
to full scale output.

Remote Sense
Fixed 5V/1A Output
The XLN series offer an extra output with a
constant output voltage of 5 VDC and a maximum
output current of 1 A for powering an additional
device. This output can be switched on or off in
the “System Setting” menu.
Up to 4 units can be connected in parallel or
series 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.
Multi-unit Control (up to 31 units)
In multi-unit control mode, up to 31 units can be
daisy chained via RS485 and controlled from one
“master” unit via the USB interface (also GPIB
and Ethernet).
The remote sense feature can compensate for up
to 2 volts of voltage drop in the load wiring. Two
small wires connect to the +S and -S sense
terminals (high input impedance) and the power
supply changes its output to make the voltage on
these sense lines equal to the voltage set on the
front panel.

Test Sequence Execution in List Mode
The list mode feature allows users to download a
list of commands to the power supply’s internal
memory and execute them. A total of 150 steps
can be allocated to each internal memory location,
up to a maximum of 10 locations. The test
sequence can be programmed remotely via the
USB, GPIB or LAN interfaces using SCPI
commands or with the included application
software. The test sequence can be configured for
one time or repeated execution. Each step settings
include voltage, current, and duration of the step
(50 ms minimum).
Create, save & load program lists. View output
characteristic curves and export data to a file.

Telnet Interface
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.
Pass/Fail test monitors maximum and minimum
voltage and current values over a specified period
of time.
