Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your particular
application.
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.
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.

MX Series 11
1. Introduction
This instruction manual contains information on the installation, operation, calibration and
maintenance of all power systems that use the MX Series power sources with the programmable
controller.
1.1 General Description
The MX Series AC and DC power source systems are high efficiency, floor standing AC and DC
power sources that provide a precise output with low distortion. Available voltage ranges are 150 Vac,
300 Vac and 400 Vac in AC mode and 200 Vdc and 400 Vdc in DC mode. The MX30-3Pi and MX45-
3Pi can operate in either single or three-phase mode. The MX30 and MX45 is also available in just
single or three-phase mode. All other models always operate in three-phase mode.
Models with a -1 or -3 designation provide full front panel operation but do not include certain features
such as arbitrary waveform generation unless added as an option at the time of order. Models with
the Pi controller offer several additional standard features, including the RS232C, USB, LAN (option)
and IEEE-488 interfaces, arbitrary waveform generation, dual voltage ranges and additional
measurement functions.
The MX Series units are contained in a compact floor standing enclosure on casters. This allows the
units to be moved around more easily.
Read the installation instructions carefully before attempting to install and operate the MX Series
power systems.
1.2 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
[e-mail]. There will be an additional charge for printed manuals.
This manual contains sections on installation, normal use, maintenance and calibration. If the MX
system is equipped with a GPIB, RS232C, USB or LAN interface, refer to the MX Programming
manual for information on using the remote control interfaces and command syntax. The
programming manual is provided on the same CDROM as this user manual.

1.3 Different Model Series
There are two versions of the MX Series product, Series I and Series II. This user manual covers both
MX model series with top level assembly part numbers 7003-400 (Series I) and 7003-422 (Series II).
The difference between the Series I and the Series II is the controller used. The Series II uses a
newer controller design but retains backward compatibility with the Series I products. The part number
is shown on the model / serial number tag on the back of the MX series. All Series II will have a
firmware revision of 4.0 or higher. The firmware revision is displayed briefly at power up on the LCD
display and can also be queried over the bus by using the *IDN? command.
Differences between the two model series are restricted to:
•Reduced number of measurement calibration coefficients on Series II.
•Increased measurement sampling rate on Series II.
•Maximum DC offset range in AC+DC mode is 250Vdc on Series I, 220Vdc on Series II
Where relevant, differences are highlighted throughout the user manual.

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 to Neutral (L-N) and phase angle specifications are valid under balanced load conditions only.
Note: Specifications for input and output current and power on MX180, MX225 and MX270
configurations are 4, 5 and 6 times those of MX45-3 and are not separately listed.

Current Limit mode Programmable, CC or CV mode
Repetitive Peak Current
Note: Maximum Peak Current shown. Value shown reflects absolute peak current protection level. This level
may not be reached under all load conditions. Depending on load conditions, peak current may max out at lower
levels due to amplifier output impedance.
Note: As of firmware revision 4.52, a repetitive peak current limit function is provided which will generate a fault
and shut off the power supply if the peak current drawn by the load exceeds the maximum level for more than 30
seconds. During this time, the amplifier will limit the peak current at a somewhat level above the maximum level but
it is not allowable to run in this mode indefinitely. This should provide sufficient time to ride through any
startup/inrush load conditions.
