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.

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 for the
standard unit.
When equipped with the -333 option, the voltage ranges are: 166 Vac, 333 Vac and 400 Vac in
AC mode and 220 Vdc and 440 Vdc in DC mode.
Output voltage options, such as the -333 option, allow testing of high voltage 480VAC L-L
products at 120% of nominal as required by IEEE 1547 (Table 1) “Interconnection system
response to abnormal voltages”.
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 [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.

2.5 Front Panel Controls
Controls:
Shuttle knob:
Allows continuous change of all values including output calibration and range change.
Decimal keypad:
Aconventional decimal keypad facilitates quick entry of numerical values such as
voltage, current limit, etc. The large blue enter key will make the value you enter
effective. Using the SETkey allows the user to preset all parameter values and update
them all at once by pressing the Enter key.
Up / d o wn a r r o w ke ys :
A s et of up and down arrowkeys is used to move the cursor position in all menus.
This allows quick selection of the desired function or parameter.
Function keys:
Measure key will display most measurement values. Program key will show all
program parameters. Output on/off key for output relay control. Phase key will
switch display to showprogram and measured values for each phase (not used on
MX15).
Displays:
LCDdisplay:
A t wo -line LCDdisplay with backlight provides easy to read guidance through all
setup operations. An adjustable viewing angle makes it easy to read from all practical
locations.
Status indicators:
Bright status indicators inform the user of important power source conditions. The
Remote lamp informs the user that the unit is under remote control. The Overload
lamp indicates that excessive current is being drawn at the output. The Over
temperature lamp illuminates when internal heat sink temperatures are too high. The
Hi Range indicator is lit any time the unit is switched to the high voltage range. The
Output On/Off indicator is on when the power source output relays are closed.
2.6 Special Features and Options
Controller Features
Mo d e :
This option is not available for the MX15.
Parallel Op e r a t i o n :
Up to three units can be paralleled in a single-phase configuration (with one master
controller and one or two auxiliary units). (MX30/2 and MX45/3). Only the master
unit requires a controller in this setup. The auxiliary units are controlled through the
system interface.
Clock and Lock Mode:
( Op t i o n -LKM a n d -LKS required).
Up to three units (all with controllers) can be connected in a one, two, or three-phase
configuration using CLOCKand LOCKconnections. Each unit requires its own

Controller Features
controller in this configuration. One unit acts as the master and provides the
reference clock to the auxiliaryunits.
Controller:

Output Relay:
Standard output relay feature to isolate power source from the load.
Ou t p u t On / Off :
The output relaycan be used to quicklydisconnect the load. An amber status
indicator displays the status of the output relay.

Misc. Options
-ES
Emergency Shut off switch. This option key lock push button is installed on the front
panel of the master MXif ordered with the MXsystem. When pushed in, the main AC
contactor is opened disconnecting the ACinput power to the MXinput transformer.
Not e that the controller (and LCDdisplay) will still be powered up but no power is
available to the amplifiers and there will be no output power either. The controller
runs off the LVsupply, which must be turned off with the front panel breaker.
After the ES has been pushed, the provided key will be required to release it. Once the
ES button has been released, the MX
must
be powered down using the front panel
circuit breaker and turned back on to start up again.
Not e :
Do not misplace the 2 keys provided, as no duplicates are available from CI. If
lost, the ES switch must be replaced. In that case, contact AMETEKProgrammable
Power customer service. ([e-mail] ).
-MB
