1. Preface

1.1 Products Outline

B&K P recision models XLN3640/XLN6024/XLN8018/XLN10014 are
programmable D C pow er supplies with s ingle ou tputs that of fer t he
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 pow er supplies come w ith the resolution of 1mV i n voltage
setting and 1mA in current setting. By connecting up to 4 power supplies in
parallel o r se ries, a maximum power out put up t o 5760 watts can be
generated. With four XLN10014 connected in s eries, the maximum output
voltage can reach 400 V. W ith four XLN3640 connected in parallel, t he
output current can reach up to 160 A.

The XLN series provides a rotary control knob and numerical and function
keys to m ake t he instrument c onvenient a nd e asy t o use. Additionally, th e
power supplies provide a memory space for storage of 10 instrument settings
that can be recalled directly. This feature offers a n easy w ay t o r estore t he
application settings. In addition, users can program to control when to cut off
the output. This feature provides extra safety f or burn-in a nd e lectroplating
applications. The supplies also pr ovide over voltage protection (OVP), over
current protection (OCP), and over power protection (OPP) features used to
keep t he out put v oltage a nd c urrent w ithin s afety le vel 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 i nput pow er a nd the l oad c hange, t he power supplies maintain a stable
output due to load and line regulation of less than 0.05%; the transient time
less than 1 m s. In remote mode, the s upplies can output a n ew
voltage/current setting 50 ms after receiving a command, which can increase
the throughput on production lines.

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 p osition, the inner f ans w ill s till r un f or approximately 10 -15
seconds to carry on the inside electric capacitor discharge process per safety
code requirement. Once the discharge p rocess is complete, this product will
carry out the automatic shut-down process

2.9 Cautions in Operation

A. While connected i n series, eac h power s upplies should be in pow er-on

state and output should be "ON". In case t here is any one supply t hat is
in power-off state or o utput 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 c onnection m ode, t he out put v oltage of e ach 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 c ut of f the output i n r esponse to t he condition. To e nsure that t he
entire test process can be complete smoothly, confirm that the input AC
voltage is within the specified range.
