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. I n 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 suppl ies 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 s etting 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 memor y 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 p r ot e ction (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 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.

the warranty of the instrument.

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 p os ition to turn off the power. After the pow e r s wi t c h i s t urned to the OFF position, the inner fans will still run for approximately 10-15 seconds to carry on the inside el ectric capacitor discharge p roces s per safe ty code requirement. Once the discharge process is complete, this product will carry out the autom atic 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 st ate 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 set ting value of each unit is not the same, the hi ghe r o ut pu t voltage will feed back to the smaller unit and destroy its inner parts.

When the AC input vol tage 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.
