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.
If this device is damaged or something is missing, contact the place
of purchase immediately.
This manual contains information and warnings that must be
followed to ensure safe operation as well as maintain the meter in
a safe condition.
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, threeconductor ac power cable. The power cable must be plugged into
an approved three-co nduc t or electr ical out let. 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
must 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 ADJ UST 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.
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.
To avoid electrical shock hazard, disconnect power cord before
removing covers. Refer servicing to qualified personnel.
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.
This product uses components which can be damaged by electrostatic discharge (ESD). To avoid damage, be sure to follow proper
procedures for handling, storing and transporting parts and
subassemblies which contain ESD
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.

1 General Information
1.1 Product Overview
The 917x and 918x series are high-performance dual range linear
DC power supplies that provide clean and reliable power with high
resolution and accuracy. All models are programmable via standard
USB interface or optional RS232, GPIB and LAN interface.
Interface cards and I/O cards come in a modular form factor.
Selected models feature high voltage outputs or dual channels to
provide series/parallel tracking functionality. All models include front
and rear panel outputs for flexibility, and feature programmable list
mode for storing and running customized test sequences.
Additionally, a unique LED test mode function can be enabled for
LED test applications requiring minimal inrush current out put. These
power supplies are suitable for bench or rack mount operation with
the available rack mount kit option.
Features

How to Install Interface Cards
1. Power off the instrument and disconnect the AC power cord
in the rear panel. Remove the back faceplate covering the
S1 or S2 slot in the rear panel by removing the two screws
on each side.
2. Make note of the metal notches that indicate where the card
should slide into. Inside the slot, there are two rails (left and
right side) where the card should slide smoothly into. The
very back of the slot is a 48-pin female connector that should
connect with the 48-pins on the back of the interface card.
3. The interface card should go right below the metal notches
on both sides and fit in between the inner card rails, also on
11

S1
both sides. Slide the card down carefully. When it touches
the 48-pin connector, slowly push the card all the way in until
the panel of the interface card aligns with the rear panel of
the power supply.
4. Place the two screws to tighten and secure the installed card.
5. Connect the power cord and turn on the power supply. The
newly installed card will be detected during boot up, indicated
next to S1: or S2: (depending on which slot the card is
installed into).
Removing Interface Cards
1. Power off the instrument and disconnect the AC power cord
2. Use a flat blade screwdriver to gently pry the left and right
in the rear panel. Remove the two screws on each side of
the installed interface card.
side of the interface card plate. When there is enough room,
12
use the screwdriver to pry the top part of the card until the
card has slid out with enough room to pull out the card by
hand.
3. Be sure to ground yourself before pulling out or touching any
parts of the printed board on the interface card.
1.8 Rackmount Installation
There are four rackmount kit options available for this series of
power supplies: 2U size for single power supply, 2U size for two
power supplies mounted side by side, 3U size for single power
supply, 3U s ize f or two power supplies mounted side by side. The
following step by step instructions will guide you in installing these
optional rackmount kits onto the power supply for a standard 19-inch
rack fitting.
Models 9171, 9172, 9181: Follow instructions for 2U rackmount
installation.
Models 9173, 9174, 9182, 9183, 9184, 9185: Follow instructions for
3U rackmount installation.

2 Getting Started
2.1 Input Power and Fuse Requirements
Input Power
The rated AC input power source for powering the supplies must be
within:
115V Operation:103.5V-126.5V
230V Operation: 207V - 253V
Frequency:47 Hz – 63 Hz
Before connecting to an AC outlet or external power source, be sure
that the power switch is in the OFF position and verify that the AC
power cord, including the extension line, is compatible with t he r ated
voltage/current and that there is sufficient circuit capacity for the
power supply. Once verified, connect the cable firmly.
WARNING:
The included AC power cord is safety certified for
this instrument operating in rated range. To change
a cable or add an extension cable, be sure that it
can meet the required power ratings for this
instrument. Any misuse with wrong or unsafe
cables will void the warranty.
Fuse Requirements
An AC input fuse is necessary when powering the instrument.
Below is a table showing the required fuses for AC line input 115V
and 230V operation for all models.
