WARNING
Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above
(below) chassis ground.
WARNING
The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.
Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your
particular application.
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.
Ensure that the AC power line ground is connected properly to the Power Rack input connector or
chassis. Similarly, other power ground lines including those to application and maintenance equipment
must be grounded properly for both personnel and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any
cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generated on the output terminals. The customer/user must
ensure that the output power lines are labeled properly as to the safety hazards and that any inadvertent
contact with hazardous voltages is eliminated.
Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety
glasses during open cover checks to avoid personal injury by any sudden component failure.
Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary
sales organizations can accept any responsibility for personnel, material or inconsequential injury, loss
or damage that results from improper use of the equipment and accessories.

User Manual Compact i/iX Series
1. Introduction
This instruction manual (P/N 6005-960) contains information on the installation, operation, calibration
and maintenance of the Compact /iX Series AC power sources, models 751i, 751iX, 1501i and 1501iX.
Series II versions are covered in this user manual.
1.1 General Description
The Compact i/iX Series of AC Power Source is a family of high efficiency, rack mountable, AC Power
Sources that provide a precisely controlled output voltage with low distortion and measurements.
Standard output voltage ranges are 150 Vac and 300 Vac RMS. The 751i/iX and 1501i/iX models
operate in single-phase mode and provide a maximum output power of 750VA (751i/iX models) or
1500VA (1501i/iX models). A unique constant power mode allows for higher output current at less than
full-scale voltage effectively increasing the usability for many applications where otherwise a higher
power level AC source may be needed.
For power levels above 1500 VA, two iX Series units can be combined using the system interface in a
parallel mode of operation. These multi chassis systems consist of one master unit with controller and
one auxiliary unit.
Read the installation instructions carefully before attempting to install and operate the Compact i/iX
Series power source.
For three phase power applications, refer to California Instruments models 2253i and 2253iX, user
manual P/N 6005-962 instead.

User Manual Compact i/iX Series
1.2 iX and i Model Differences
The iX models offer additional features and functions over the i models. Some of the features available
on the iX models such as the GPIB interface may be added as an option to the i models at the time of
order. Other features are exclusive to the iX models.
Both models are based on the same AC power source hardware platform and share many common
components. The differences are primarily in configuration and options. This manual covers both
models. Some menus and screen shown in this manual may not apply to i model AC sources.
All 751i/iX and 1501i/iX models are equipped with a USB interface. The iX models also include a GPIB
interface. The GPIB interface can be specified as an option on the i models at the time of order. An
optional Ethernet interface (-LAN) is available on the iX models.
1.3 Manual organization and format
All user documentation for California Instruments power sources is provided on CDROM in electronic
format. (Adobe Portable Document Format) The required Adobe PDF viewer is supplied on the same
CDROM. This manual may be printed for personal use if a hardcopy is desired. To request a hardcopy
from AMETEK Programmable Power, contact customer service at support@programmablepower.com.
There will be an additional charge for printed manuals.
This manual contains sections on installation, normal use, maintenance and calibration.
Refer to the iX Series Programming manual for information on using the remote control interface and
command syntax. The programming manual (P/N 6005-961) is provided on the same CDROM as this
user manual.
AMETEK Programmable Power may make updated versions of this manual available from time to time
in electronic format through it’s website. To obtain an updated manual revision if available, check the
California Instruments Manual download page at www.programmablepower.com. You need to register
as a customer to obtain free access to manual and software downloads.

2. Specifications
Specifications shown are valid over an ambient temperature range of 25 5 C and apply after a 30
minute warm-up time. Unless otherwise noted, all specifications are per phase for sine wave output
into a resistive load. For three phase configurations or mode of operation, all specifications are for Line

External Trigger Output
or Function Strobe
An external TTL output is available which may be used to trigger other
equipment. The TTL output can be controlled by the transient
programming system. This requires the trigger mode to be set to EXT
(factory default). This can only be done over the computer interface
using the OUTP:TTLT:MODE TRIG command.
It can also be configured to generate an output pulse any time the
voltage, frequency, current limit or phase programming is updated. This
requires the trigger mode to be set to FSTR. This can only be done over
the computer interface using the OUTP:TTLT:MODE FSTR command.
This mode is compatible with the CI Lx/Ls Series.
The Trigger Output (Trig Out) / function strobe is an active low TTL
signal with a duration of no less than 400 us.
Clock and Lock Mode
Enables two or more independent iX power systems to be phase
synchronized to each other. One system (-LKM) acts as the master, the
other(s) (-LKS) as auxiliaries. The –LKS units are synced to the –LKM
unit. Refer to section 3.10 for details on Clock and Lock mode.
Trigger Input
A TTL input signal may be used as a trigger source for output changes
programmed on the AC power source transient system. This requires the
trigger source to be set to EXT. This can only be done via one of the
computer interfaces. An external trigger source may be used to control
the execution of output sequences that have been pre-programmed into
the power source transient system. Refer to i/iX Series Programming
Manual (6005-961) for details.
