1. Preface
1.1 Products Outline
B&K Precision models XLN3640/XLN6024/XLN8018/XLN10014 are
programmable DC power supplies with single outputs that offer the maximum
power output up to 1440 watts (0 -- 36 V/40 A or 0 -- 60 V/24 A or 0 -- 80
V/18 A or 0 -- 100 V/14.4 A). With a 16-bit D/A, A/D converter embedded,
the power supplies come with the resolution of 1mV in voltage setting and
1mA in current setting. By connecting up to 4 power supplies in parallel or
series, a maximum power output up to 5760 watts can be generated. With four
XLN10014 connected in series, the maximum output voltage can reach 400 V.
With four XLN3640 connected in parallel, the output current can reach up to
160 A.
The XLN series provides a rotary control knob and numerical and function
keys to make the instrument convenient and easy to use. Additionally, the
power supplies provide a memory space for storage of 10 instrument settings
that can be recalled directly. This feature offers an easy way to restore the
application settings. In addition, users can program to control when to cut off
the output. This feature provides extra safety for burn-in and electroplating
applications. The supplies also provide over voltage protection (OVP), over
current protection (OCP), and over power protection (OPP) features used to
keep the output voltage and current within safety level and preventing damage
to the UUT (Unit Under Test) due to excessive current. The key lock feature
is added to avoid accidental setting changes to the XLN series. When the input
power and the load change, the power supplies maintain a stable output due
to load and line regulation of less than 0.05%; the transient time less than 1
ms. In remote mode, the supplies can output a new voltage/current setting
50 ms after receiving a command, which can increase the throughput on
production lines.

1.2 Features
1) Output Voltage & Current
Voltage output range: 0 -- 36V (XLN3640) / 0 -- 60V (XLN6024)
0 -- 80V (XLN8018) / 0 -- 100V (XLN10014)
Current output range: 0 -- 40A (XLN3640) / 0 -- 24A (XLN6024)
0 -- 18A (XLN8018) / 0 -- 14.4A (XLN10014)
Power output range: 0 -- 1440W
2) Rotary knob, numerical keys and functions keys
The rotary knob can be used to rapidly change the output voltage setting and
simulate the surge of the voltage output. It offers a good solution for testing
triggering circuits. Numerical keys allow for direct entry of parameters.
Using function keys to switch modes makes the overall operation more
convenient.
3) Precise voltage and current measurement
Besides the precise output, the XLN series also offers the capability to
measure voltage & current accurately (read back), saving users the extra
expense and space for extra measuring instruments.
4) Internal memory and timer function
The XLN series provides a memory space for storage and retrieval of 10
instrument settings. The instruments provide one (1) timer with the
resolution of 1 second. The timers are used to time the outputs. When the
timer counts down to zero the power supply will automatically turn the
output off. This feature is useful when the supply is providing power to the
test object in a burn-in room where operators can precisely set the time when
the equipment is to shut off.
5) OVP (over voltage protection), OCP (over current protection) and OPP
(over power protection) and key lock functions
The over voltage protection (OVP), over current protection (OCP) and over
power protection (OPP) features limit the maximum output current and
voltage to avoid damages to the unit under test (UUT). The key lock feature
disables all keys except the CLR key. It prevents damaging the UUT by
accidentally entering the wrong settings.
6) Series & parallel connection mode
1-3
The series-parallel connection mode of two or more units (maximum to 4
units) significantly increases the combined output power to a maximum of
5760 W. In parallel connection mode of four XLN3640 the maximum
output is 36 V/160 A; and in series connection mode of four XLN10014,
the maximum output is 400 V/14.4 A.
7) Multi-unit connection mode
The RS 485 interface can be used to connect multiple power supplies in
series, up to maximum of 30 units. They can be controlled via USB
interface with a computer.

2.4 Storage
Warning:
The power cable attached with this product is certified for
safety. To change a cable or add an extension cable, be
sure that it can meet the required power ratings of this
product. Any misuse with an additional cable would
void the warranty of this product.
Warning:
Any disassembling of the casing or changing the fuse not
performed by an authorized service technician will void
the warranty of the instrument.
The storage temperature range of this product is within -10ºC - 70ºC and R.H.
should be within 80% without moisture condensing. If not operating this
product for a long time interval, pack it with original packaging or similar one
and put it in a dry place without exposure to direct sunlight.
2.5 Power-line voltage
Rated AC power source connected to this product is within 100 V-240 V (refer
to the Product Specification for details). Before connecting to external power
source, be sure that the power switch is in OFF state and verify the suitability
of power cable (including the extension line). It should be compatible with the
rated voltage/current and should be firmly connected.
2.6 Fuses
This product is a switching mode power supply. The fuse installed inside is a
multi-barrier protection hardware design. It should not break under normal
operation. In case the fuse does melt, it indicates another malfunction that
causes the fuse to break. In this case, it is suggested to send this product back
to service.
1-11
2.7 Warm-up Time
The XLN series is fully operable upon switching the power on. However, to
reach the specified equipment accuracy, please allow the supply to warm up
for at least 30 minutes.
2.8 Power-off procedure
When the supply is not in use, be sure to turn the power switch on the panel
to the OFF position to turn off the power. After the power switch is turned to
the OFF position, the inner fans will still run for approximately 10-15 seconds
to carry on the inside electric capacitor discharge process per safety code
requirement. Once the discharge process is complete, this product will carry
out the automatic shut-down process
2.9 Cautions in Operation
A. While connected in series, each power supplies should be in power-
on state and output should be "ON". In case there is any one supply that is
in power-off state or output is "OFF", the associated output current will
flow over the output bypass diode of the power-off unit and burn it out.
B. While in parallel connection mode, the output voltage of each power
supplies should be set to equal values. If the setting value of each unit is
not the same, the higher output voltage will feed back to the smaller unit
and destroy its inner parts.
C. When the AC input voltage is lower than the full-load voltage which
is 100 VAC, the supplies will activate an inner over temperature protector
and cut off the output in response to the condition. To ensure that the entire
test process can be complete smoothly, confirm that the input AC voltage
is within the specified range.
