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 – Rev M California Instruments
1 Introduction
This instruction manual contains information on the installation, operation, calibration and
maintenance of all power systems that use the MX15 Series power sources with the
programmable controller.
1.1 General Description
The MX15 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.
Models with a -1 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 MX15 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 MX15
Series power systems.
1.2 Manual organization and format
All user documentation for AMETEK programmable power sources is provided on CDROM in
electronic format. (Adobe Portable Document Format) The required Adobe PDF viewer can be
downloaded free of charge from www.adobe.com. 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 service@programmablepower.com. 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.

Programmable impedance is turned off as soon as a regenerative load is

again. This is required as programmable impedance is based on

2.6.6 SNK Option Specifications
The –SNK or current sink option enables the MX power source to sink current from the unit
under test. This mode of operation is particularly useful when testing grid-tied products that feed
energy back onto the grid. The ability of the MX to simulate the grid provides unique opportunities
to test the EUT for compatibility to commonly occurring line anomalies like voltage and/or
frequency fluctuations. Examples of these types of EUT are inverters (PV Solar, Wind) hybrid
drive systems, regenerative breaks.
The SNK option requires special amplifiers that have a different control loop from the standard
MX amplifiers. In the AC mode the upper frequency limit of an MX configured with the –SNK
option is 500Hz as opposed to the standard 819Hz. Also, the voltage distortion levels are slightly
higher than on MX units without this option.
All other specifications of the MX system remain unchanged if this option is installed.
The distortion specification for the MX Series is valid for pure (inductance < 12 uH) resistive load conditions and
using a 30 KHz LP filter on distortion meter.

2.7.3 Output Noise Spectrum
The MX series is a switching power supply and as such will have a certain amount of switching
noise at its output. While the overall RMS noise is specified, the specific noise spectrum will
differ slightly from unit to unit. The information provided in this section is for reference only.
The output noise can be reduced by using one or more external filters. A suitable filter is the P/N
7003-424-1 (Figure 2-9) available from AMETEK as an option. Attenuation at the 250 kHz ripple
frequency is 20 dBuV. The output voltage drop at 800 Hz full load is less than 1Vrms.
Typical output noise spectrum for a standard MX45-3Pi in three phase mode operating at 400 Hz
is shown in Figure 2-10 for phase A and Neutral. The same output with the use of the optional
filter is shown in Figure 2-11. For connection information, refer to section 3.14. The MX15 and
MX45 use the same amplifier so results will be similar.
