MX Series II

Product Evaluation and Test
Increasingly, manufacturers of high power
equipment and appliances are required to fully
evaluate and test their products over a wide
range of input line conditions. The built-in output
transient generation and read-back measurement
capability of the MX Series offers the convenience
of a powerful, and easy to use, integrated test
system.

Avionics
With an output frequency range to 819 Hz
(or 1000 Hz with -HF option), the MX Series is
well suited for aerospace applications. Precise
frequency control and accurate load regulation
are key requirements in these applications. The
available IEEE-488 remote control interface
and SCPI command language provide for easy
integration into existing ATE systems. The MX
Series eliminates the need for several additional
pieces of test equipment, saving cost and space.
Instrument drivers for popular programming
environments such as National Instruments
LabView™ are available to speed up system
integration.

Regulatory Testing
As governments are moving to enforce product
quality standards, regulatory compliance testing
is becoming a requirement for a growing number
of manufacturers. The MX Series is designed
to meet AC source requirements for use in
compliance testing such as IEC 61000, 3-2, 3-3,
3-11, 3-12, to name a few.

Choice of voltage ranges
The MX30 and MX45 can be ordered with either
a 150 V RMS Line to Neutral output voltage
range or a 300 V RMS Line to Neutral range. This
provides 3 phase output capability of 260 Vac or
520 Vac line to line respectively. If dual output
ranges are required, the programmable range
change option (-R) provides the ability to switch
between both output ranges. Pi version models
offer standard dual voltage ranges.

The DC output mode changes the 150 V AC
range to a 200 V DC output range; the 300 V AC
range becomes 400 V DC.

For applications requiring more than 300 V
L-N (or 520 V L-L), the optional -HV output
transformer provides an additional 400 V L-N
and 693 V L-L output range for use in AC mode
only.

Multi-Box Configurations
For high power applications, two or three
MX45 chassis can be combined to provide 90
to 135 kVA of three phase power. MX90 and

MX135 systems are always configured for three
phase operation. Contact sales for custom
configurations.

High Crest Factor
With a crest factor of up to 3.6, the MX Series
AC source can drive difficult nonlinear loads with
ease. Since many modern products use switching
power supplies, they have a tendency to pull
high repetitive peak currents. The MX30-3Pi can
deliverup to 240 Amps of repetitive peak current
(150 V AC range) per phase to handle three
phase loads. The MX45-3Pi can deliver up to 360
Amps. 720 Amps (MX30), and 1080 Amps (single
phase mode).

Remote Control
Standard RS232C & USB along with optional
IEEE-488 & LAN remote control interfaces allow
programming of all instrument functions from an
external computer. The popular SCPI command
protocol is used for programming.

Application Software
Windows® application software is included with
both versions. This software provides easy access
to the power source’s capabilities without the
need to develop any custom code. The following
functions are available through this GUI program:

• Steady state output control (all parameters)
• Create, run, save, reload and print

transient programs

• Generate and save harmonic waveforms.

[Pi only]

• Generate and save arbitrary waveforms.

[Pi only]

• Measure and log standard measurements
• Capture and display output voltage and

current waveforms. [Pi only]

• Measure, display, print and log harmonic

voltage and current measurements. [Pi only]

• Display IEEE-488, RS232C, USB and LAN bus

traffic to and from the AC Source to help you
develop your own test programs.
