Safety Summary

The following safety precautions apply to both operating and maintenance personnel

and must be observed during all phases of operation, service, and repair of this

instrument. Before applying power, follow the installation instructions and become

familiar with the operating instructions for this instrument.

Failure to comply with these precautions or with specific warnings elsewhere in this

manual violates safety standards of design, manufacture, and intended use of the

instrument. B&K Precision assumes no liability for a customer’s failure to comply

with these requirements. This is a Safety Class I instrument.

GROUND THE INSTRUMENT

To minimize shock hazard, the instrument chassis and cabinet must be

connected to an electrical ground. This instrument is grounded through the

ground conductor of the supplied, three-conductor ac power cable. The

power cable must be plugged into an approved three-conductor electrical

outlet. Do not alter the ground connection. Without the protective ground

connection, all accessible conductive parts (including control knobs) can

render an electric shock. The power jack and mating plug of the power cable

meet IEC safety standards.

DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE

Do not operate the instrument in the presence of flammable gases or fumes.

Operation of any electrical instrument in such an environment constitutes a

definite safety hazard.

KEEP AWAY FROM LIVE CIRCUITS

Instrument covers must not be removed by operating personnel. Component

replacement and internal adjustments must be made by qualified maintenance

personnel. Disconnect the power cord before removing the instrument

covers and replacing components. Under certain conditions, even with the

power cable removed, dangerous voltages may exist. To avoid injuries,

always disconnect power and discharge circuits before touching them.

DO NOT SERVICE OR ADJUST ALONE

Do not attempt any internal service or adjustment unless another person,

capable of rendering first aid and resuscitation, is present.

DO NOT SUBSTITUTE PARTS OR MODIFY THE INSTRUMENT

Do not install substitute parts or perform any unauthorized modifications to

this instrument. Return the instrument to B&K Precision for service and

repair to ensure that safety features are maintained.

WARNINGS AND CAUTIONS

WARNING and CAUTION statements, such as the following examples,

denote a hazard and appear throughout this manual. Follow all instructions

contained in these statements.

A WARNING statement calls attention to an operating procedure, practice, or

condition, which, if not followed correctly, could result in injury or death to

personnel.

A CAUTION statement calls attention to an operating procedure, practice, or

condition, which, if not followed correctly, could result in damage to or

destruction of part or all of the product.

WARNING: Do not alter the ground connection. Without the protec

tive ground

connection, all accessible conductive parts (including control knobs)

can render an electric shock. The power jack and mating plug of the

power cable meet IEC safety standards.

WARNING: To avoid electrical shock hazard, disconnect power cord

before

removing covers. Refer servicing to qualified personnel.

CAUTION:

Before connecting the line cord to the AC mains, check the rear panel

AC line voltage indicator. Applying a line voltage other than the

indicated voltage can destroy the AC line

fuses. For continued fire

protection, replace fuses only with those of the specified voltage and

current ratings.

CAUTION:

This product uses components which can be damaged by

electro-

static discharge (ESD). To avoid damage, be sure to follow

proper pr

ocedures for handling, storing and transporting parts and

subassemblies which contain ESD-sensitive components.

Store/Move/Maintain

Storage

When this device is not in use, properly package it and store it in an

environment suitable for storage (if present in a good preserving environment,

the packaging process can be waived).

Freight

While moving this product, move it by using the original packaging to pack

this product in advance. If the packaging material is lost, use an equivalent

buffer material to replace it in packaging; and with external marks indicating

“fragile & water-prevention”.

Maintenance

Please return the power supply to factory for any repair, service, or

maintenance.

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

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.
