SAFETY NOTICE

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

CE recognition of DP 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 DP Series power supplies may be connected in series. For models rated 1000 V or
less and 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. For models rated greater that 1000 V and 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 4000 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.

These operating instructions form an integral part of the equipment and must be available to the
operating personnel at all times. All the safety instructions and advice notes are to be followed.

1.0 GENERAL INFORMATION

1.1 Description

This manual contains operation and maintenance instructions for Magna-Power Electronics' DP
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’ DP Series combines the best of dc power processing with
multiprocessor embedded control. A combination of high and medium frequency power
processing technologies improves response, shrinks package size, and reduces cost. DP Series
power supplies are current fed and are more tolerant to abusive loads than conventional
switching power supplies.

DP Series power supplies can operate as a voltage source or 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.

DP 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.

DP Series power supplies have fully isolated dual outputs that can be configured for independent
control or configured for series master/slave operation. The two power processing modules,
with its independent control circuits, can operate as voltage sources or current sources depending
on the control settings and load conditions.

When configured for master/slave operation, the master unit provides the positive output voltage
and the slave unit provides the negative output voltage. With A or D front panels, controls and
indicators for the master modules are on the top of the front panel and the controls and
indicators for the slave module are on the bottom of the front panel. A shorting output bus bar is
provided to produce a plus and minus output voltage with a common midpoint connection.

DP 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. DP 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.

DP 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.

DP 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.

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

DP Series models utilizing the A Version front panel, DPA, 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. DPA Series power supplies are well suited for
industrial applications requiring a minimum of control.

DP Series models utilizing the D Version front panel, DPD, provide all of the features of the A
Version plus these models can be configured for keypad entries and up/down presses for voltage,
current, over voltage trip, and over current trip. Key strokes are kept to a minimum by a repeat
last command feature. DPD Series power supplies are well suited for laboratory applications
requiring enhanced control.

DPD Series models have one-hundred memory states available to program voltage, current, over
voltage trip, over current trip, and time period. Set points can be auto sequenced with time or
external triggering. Special programming codes allow repeating to create a power function
generator. The first 10 memory states are displayed on the front panel to simplify programming
tasks.

DPD Series power supplies 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

allows the output to be tailored for advanced process control applications, battery charging, and
source emulation.

DP Series models utilizing the C Version front panel, DPC, 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.

DP 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, fuse clearing, 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 rear
connectors to allow simultaneous control of one or more DP Series units.

2.0 INSTALLATION AND POWER ON CHECK

DP 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

DP Series power supplies are cooled by air or water. Air cooled power supplies are for general
use. Water cooled power supplies are for use in corrosive environments such as plating
applications or in densely packaged system cabinets where heat removal by air cooling presents
a problem. The method of cooling must be specified at time of order.

2.1.1 Air 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 DP 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 800 CFM.

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

2.1.2 Water Cooling

Water cooling is accomplished with chill plates and an integrated central heat exchanger. The
chill plates provides a thermal conduction path for heat sensitive components and the central heat
exchanger removes heat from air internal to the enclosure. Water cooled DP Series models have
enclosures without vent holes and are basically sealed the unit from the environment. An
internal solenoid valve enables water flow when the chill plate reaches 60°C. Operation of the
solenoid prevents internal condensation.
