USER MANUAL

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 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.

WARNING:

To avoid electrical shock hazard, disconnect power cord before

removing covers. Refer servicing to qualif

ied 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 procedures for handling, storing and transporting parts and

subassemblies which contain ESD

-sensitive components.

1. Introduction

1.1 Product Summary

B&K Precision’s high voltage XLN series are programmable DC power

supplies with single outputs that offer maximum power output up to 1560 W.

With a 16-bit D/A, A/D converter embedded, the power supplies provide

voltage and current resolution of 1 mV and 1 mA. By connecting up to 4

power supplies in parallel, maximum output power can reach 6240 W.

Additionally, the power supplies have extensive protection features for safe

operation, such as overvoltage protection (OVP), overcurrent protection

(OCP), and overpower protection (OPP). For remote operation, the high

voltage XLN series offers standard USB, RS-485, and analog interface for

versatile remote controllability. Optionally, users can also add LAN and

GPIB interface capability (-GL versions).

1.2 Features

1) Output Voltage & Current

Voltage output range: 5 – 150 V (XLN15010)

5 – 300 V (XLN30052)

5 – 600 V (XLN60026)

Current output range: 0.04 – 10.4A(XLN15010)

0.02 – 5.2 A (XLN30052)

0.01 – 2.6 A (XLN60026)

Power output range: 0 – 1560 W

2) Rotary knob, numerical keys and function 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 high voltage XLN series also offers the

capability to measure voltage and current accurately (readback), saving

users the additional expense and space for extra measuring instruments.

4) Internal memory and timer function

The high voltage XLN series provides internal memory for storage and

retrieval of 10 instrument settings. The instruments provide one 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) Programmable sequence mode (List mode)

Programmable list mode allows users to create test sequences to store and

run inside the power supply using remote commands sent via USB, GPIB,

and LAN. Up to 10 program sequences can be stored, each allowing a

maximum of 150 steps.

6) OVP (overvoltage protection), OCP (overcurrent protection), OPP

(overpower protection) and key lock functions

The overvoltage protection (OVP), overcurrent protection (OCP) and

overpower 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.

7) Parallel connection mode

The parallel connection mode of two or more units (maximum 4 units)

significantly increases the combined output power to a maximum of 6240

W. For example, in parallel connection mode withfour XLN15010, the

maximum output is 150 V/41.6 A.

8) 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.

1.3 Specifications

Note: All specifications apply to the unit after a temperature

stabilization time of 15 minutes over an ambient temperature range

of 23 °C ± 5 °C. Specifications are subject to change without

notice.
