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 suppli es 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 (ov er voltage protection), OCP (over curren t protection) a n d OP P (over power pr otection) and key lock functions

The over volt a ge 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 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 31 units. They can be controlled via USB interface with a computer.

vibration, or corrosive gas and do not expose this product directly t o the sunlight. Operate it in an environment with temperature 0--40

C & relative humidity 20%--80%. Pause the operation when ambient temperature is over 40

C; undo the operation only after the ambient temperatures drops to the acceptable temperature range. Operating temperature over the above range would damage the instrument.

2. This product is equipped with one blow-out type cooling fan on the

back board and three in-take cooling fans on inner side of front board. Provide room for good ventilation near the cooling fans and keep the boards with a space above 10cm away from wall. To maintain good accuracy, do not block the ventil ation holes in the front and the rear parts of the unit.

3. Although the product is designed with filters to minimize noise from

AC power source, it is recommended that it be operated in a low power noise environment with proper earth ground. If the power noise is unavoidable, please install a power filter.

2.4 Storage

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.

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.

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.

Warning: Any disassembling of the casing or changing the fuse not

performed by an authorized service technician will void the warranty of the instrumen t.

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 OF F p os i t ion to turn off the power. After the pow e r switch is t ur n ed to the OFF position, the inner fans will still run for approximately 10-15 seconds to carry on the inside electric capacitor discharge pr ocess per safet y 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 c urrent 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 high er o utp ut voltage will feed back to the smaller unit and destroy its inner parts.

When the AC inp ut voltage is lower than the full-load voltage which i s

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.

6. Remote Interface communication protocol

The communication protocol includes standard SCPI commands and a few proprietary commands which follow the SCPI convention.

6.1 Prefaces

The SCPI interface enables users to operate the model XLN3640/XLN6024/XLN8018/XLN10014 supply through a computer or a terminal equipped with IEEE-488.2 GPIB or USB interface. Additionally, it allows remote control and monitoring.

SCPI IEEE-488.2 version supports multi units control capability that allows a user to control up to 32 XLN3640/XLN6024/XLN8018/XLN10014 units.

6.2 Parameters Definition

Type

Valid Arguments

" ON" or 1, " OFF" or 0

<NR1 > The data format <NR1> is defined in IEEE-488.2 for

integers. Zero, positive and negative integer numeric values are valid data.

<NRf >

The data format <NRf> is defined in IEEE-

488.2 for

flexible Numeric Representation. Zero, positive and negative floating-point numeric values a

re some

examples of valid data.

Characters enclosed by single or double quotes

<LF > Line Feed, Hex code is 0x0Ah <CR> Carriage Return, Hex code is 0x0Dh <END > End or identify

Note: All commands are terminated with <CR> and <LF> characters. A

space is always included in between the command and the parameter.

For example, to set the GPIB address of 10 to a

XLN3640/XLN6024/XLN8018/XLN10014. The command line is sent:

ADDR 10<CR><LF>

Note: The <LF> and <CR> are not presented in the following examples and

command descriptions. However, users must add t hem as termination

characters at the end of each command when programming.

6.3 The Error/Event List

SCPI interface can offer an error/event list that contains up to 10 e rror s/eve nts. Users can read the errors/events through the “error?” command in a first-in first-out manner. Once an error/event is read, the read process will clear it from the memory. To clear all errors/events from the memory, the “*CLS” command is used.
