SAFETY NOTICE

Before applying power to the system, verify that the unit is configured properly for the user’s
particular application.

CE recognition of XR Series power supplies is based on rack mounted applications only. Use of
these power supplies outside of a rack mount equipment enclosure will expose the user to high
voltage and/or high current sources. Extreme caution must be used under these circumstances.

Two or more XR Series power supplies may be connected in series. Regardless of the number
of units or the voltage ratings of the series connected power supplies, the voltage potential from
any output terminal to chassis ground should not exceed 1000 Vdc.

Installation and service must be performed only by properly trained and qualified personnel who
are aware of dealing with electrical hazards. Ensure that the ac power line ground is properly
connected to the power supply chassis. Furthermore, other power grounds, including those
connected to application maintenance equipment, must be grounded for both personnel and
equipment safety.

Always ensure that facility ac input power is de-energized prior to connecting or disconnecting
the input and output power cables.

Caution: Lethal voltages may be present inside the power supply even when the
ac input voltage is disconnected. Only properly trained and qualified personnel
should remove covers and access the inside of the power supply.

During normal operation, the operator does not have access to hazardous voltages within the
cabinet. Depending on the user’s application, high voltages hazardous to human safety may be
generated normally on the output terminals. Ensure that the output power cables are properly
labeled as to the safety hazards and that any inadvertent contact with hazardous voltages is
eliminated.

This power supply is designed to be permanently connected to the power source requiring a
readily accessible disconnect device incorporated in the fixed wiring.

1.0 GENERAL INFORMATION

1.1 Description

This manual contains operation and maintenance instructions for Magna-Power Electronics' XR
Series, current fed power supplies. These power supplies are constant voltage/constant current
sources suitable for a wide range of applications.

1.2 Features

Magna-Power Electronics’ XR Series combines the best of dc power processing with
multiprocessor embedded control. Magna-Power Electronics’ innovative power processing
technology improves response, shrinks package size, and reduces cost. XR Series power
supplies are current fed and are more tolerant to abusive loads than conventional switching
power supplies.

XR Series power supplies can operate as a voltage source or a current source depending on the
control settings and load conditions. If the power supply is operating as a voltage source and the
load increases to a point beyond the current command setting, the power supply automatically
crosses over to current mode control and operates as a current source at that setting.

XR Series power supplies incorporate an optically isolated feedback system. The result is that
all user interface circuitry is referenced to earth ground -- not the negative terminal of the power
supply. This enables users to connect external circuitry without concern of ground loops or
voltage breakdown.

XR Series power supplies offer both master/slave parallel and series operation. This enables two
or more power supplies to be placed in parallel for increased output current or in series for
increased output voltage. With master/slave operation, power supplies operate at near equal
voltage and current.

XR Series power supplies can be configured through the front panel for different applications.
The power supply can be programmed to have its control functions accessible from the front
panel, rear connector, or with RS232, optional IEEE-488, or optional Ethernet communications.
External RS485 to RS232 and external USB to RS232 converters are also available to echo
commands over the communications network. Communication options must be specified at time
of order. XR Series power supplies support a full set of SCPI commands. Drivers are available
for LabWindows/CVI, LabVIEW, and IVI.

Sensing can be established at the output terminal of the power supply or through a rear terminal
block for sensing at the load. A smart remote sense detector checks whether or not sense leads
are present eliminating the potential of uncontrolled operation. An external interlock can be set
to enable operation only when an external connection is made. Even calibration has been
simplified with front panel access to calibration digital potentiometers.

1

XR Series power supplies have three levels of over voltage/current protection: shutdown of
controlling insulated gate bipolar transistors (IGBT’s), disconnect of main power, and input
fuses. After an over voltage/current trip condition, the supply must be reset.

XR Series power supplies have push button start/stop controls. These controls are tied to a
mechanical contactor which operates with the electronic switches to break the ac mains when
stop is commanded. Unlike competing products, an off means both an electrical and mechanical
break in the power circuit — not a break in an electronic switch. Safety comes first at Magna­Power Electronics.

XR Series power supplies are available with two alternative front panels: XR Version for
analog/digital control and C Version for computer or programmable logic control. All XR Series
power supplies employ the same power processing engine. Table 1.1 shows a comparison
between the different models.

XR Series models utilizing the XR Version front panel provide stepless analog control from
front panel potentiometers. With simple configuration changes, voltage, current, over voltage
trip, and over current trip may be programmed from the rear connector or with RS232, optional
IEEE-488, or optional Ethernet communications. XR Series power supplies with XR Version
front panels are well suited for industrial and laboratory applications.

XR Series power supplies with XR Version front panels offer an analog input to modulate the
voltage or current setting using piecewise linear approximation. This feature enables the voltage
or current setting to be adjusted by a sensor input, such as a thermistor, or by monitoring its own
voltage or current. Modulation allows the output to be tailored for advanced process control
applications, battery charging, and source emulation.

XR Series models utilizing the C Version front panel only allow control from the rear connector
or with RS232, optional IEEE-488, or optional Ethernet communications. These models are
intended for process control applications where front panel controls and displays are not required
or desired.

Remote Interface Software is included to provide sophisticated computer control. This software
provides a virtual control panel to emulate the power supply’s front panel, a command panel to
send and monitor SCPI commands, a register panel to monitor registers, a calibration panel to
provide easy access to calibrate digital potentiometers, a firmware panel to upgrade the control
microprocessor, and a modulation panel to easily program modulation parameters.

XR Series models have extensive diagnostic functions -- all of which when activated take
command to shut down the system. Diagnostic functions include phase loss, excessive thermal
conditions, over voltage trip, over current trip, and program line. Program line monitors
externally applied analog set point signals to insure they are within the specified range. Upon a
diagnostic fault condition, main power is disconnected and the diagnostic condition is latched
into memory. Pressing the clear key clears the memory. All diagnostic functions can be
monitored through a rear connector. Furthermore, control functions can also be set through the
rear connector to allow simultaneous control of one or more XR Series units.

2.0 INSTALLATION AND POWER ON CHECK

XR Series power supplies are intended for rack mount installations only and are designed to fit
in standard 19" equipment racks. Additional support, other than that provided by the front panel,
is required. Angle slides or cross beam supports securely fastened to the rack are recommended
for supporting the weight of the power supply. The unit should be horizontally mounted.

Caution: The power supply is too heavy for one person to safely lift and mount.
To avoid injury, ask a co-worker for assistance.

2.1 Cooling

Each power supply enclosure is cooled by suitable blowers exhausting warm air to the rear of the
cabinet. Fresh air intake is from the sides of the cabinet allowing two or more XR Series
supplies to be stacked. Equipment racks should be equipped with fans or blowers to remove heat
generated by the power supplies. The manufacturer recommends fresh air intake at the bottom
of the cabinet and exhaust at the top. Fans and blowers should be rated at 300 CFM for each XR
Series supply.

Caution: blocking ventilation will cause the power supply to overheat.

2.2 AC Input Connections

Caution: disconnect AC power from the mains before attempting any
installation procedure.

Caution: a safety ground wire must be connected to the unit as indicated by
the protective ground symbol at the rear of the power supply.

AC power is wired to the power supply by attaching three cables plus ground for 3-phase
installations and two cables and ground for single phase installations. The manufacture
recommends cables, as specified in Tables 2.1 or 2.2, be crimped to ring terminals and securely
fastened to the studs at the rear of the power supply. After connections are made, screw the four
standoffs into the back panel and place the protective shield over the connections.
