Magna-Power Electronics
Programmable DC Power Supplies
Technology and Feature Overview
Innovative and Scalable
Magna-Power Electronics programmable DC power supplies
combine the best of DC power processing with microprocessor embedded control. A combination of high and medium
frequency power processing technologies improves response,
shrinks package size, and reduces cost. All Magna-Power
Electronics DC power supplies are current-fed and are more
tolerant to abusive loads than conventional switching power
supplies. This technology allows the power supply to operate
under short-circuit conditions, open-circuit conditions and
everything in between.
The programmable DC 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, within the
unit’s isolation limits. With master/slave operation, power
supplies operate at near equal voltage and current. The process of master/slaving power supplies is plug & play with the
use of Magna-Power Electronics UID47 option, which can be
added at any time.
All 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.
Designed for Safety
Magna-Power Electronics programmable DC power supplies 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 specifi ed 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 the rear connector and software. Furthermore, control functions can also be
set through the rear connector to allow simultaneous control
of one or more power supplies.
The power supplies have three levels of over voltage/current
protection: shutdown of controlling insulated gate bipolar
transistors (IGBTs), disconnect of main power and input
fuses. After an over voltage/current trip condition, the supply fault must be cleared.
Isolated External I/O for Automation
Using the rear isolated 37-pin I/O connector, the programmable power supplies can be completely controlled and
monitored using external signals. The voltage, current, over
voltage and over current set points are set by applying a
0-10V analog signal. Each diagnostic condition is given a
designated pin, which reads +5V when high. Reference +5V
and +10V signals are provided, eliminating the need for
external voltage signals and allowing the use of dry contacts.
Also, the power supply features a normally closed external
interlock, which when enabled, allows the power supply to
be tied in with other emergency stop equipment. All these
pins are isolated to earth-ground as standard—no additional
isolation equipment or options necessary.
Fully Programmable
The Magna-Power Electronics programmable DC power
supplies can be programmed and monitored using three possible sources:
• Stepless front panel programming knobs
• External analog/digital signals
• Computer interface through included software, Lab-
VIEW, or other programming environemnt
The power supply can be programmed to have its control
functions accessible from the front panel, rear connector,
RS232 (standard), LXI TCP/IP Ethernet (+LXI), IEEE
488 GPIB (+GPIB), USB Edgeport (+USB), or RS485DSS
(+RS485) communications. The included IVI driver enables
programming in a variety of software environments, including: Visual C++, Visual C#, Visual Basic .NET, Visual
Basic 6.0, LabVIEW, LabWindows/CVI, MATLAB, Measure
Foundry, and Agilent VEE Pro. Basic programming requirements are satisfi ed by the instrument’s supported Standard
Commands for Programmable Instruments (SCPI). Sensing can be established at the output terminal of the power
supply or through a rear remote sense terminals for sensing
at the load. Even calibration has been simplifi ed with front
panel access to digital calibration potentiometers.
Attention to Power Quality
All Magna-Power Electronics power supplies contain circuitry to work harmoniously with other power equipment.
Step-start contactors are used to keep inrush current below
full scale operating current. Filter components lower current
harmonic content emanating from the power supply and increase power factor to levels beyond 90%. Every power supply is tested at 90% to 125% nominal line to insure satisfactory operation even under the worst line voltage conditions.
Electronic Output Stage
The novel electronic output stage (XR/TS/MS Series) utilizes
near constant power loading under all conditions via an
electronic bleed resistance. This electronic bleeder means
stability under all operating conditions and faster fall times,
without affecting the overall system effi ciency.

High Isolation Output
Option Code: +ISO
Products Supported: TS Series, MS Series, MT Series
Certain applications require fl oating the output voltage to
values beyond the power supply’s standard isolation rating. Magna-Power Electronics High Isolation Output option
(+ISO) enables any TS Series, MS Series, or MT Series
model with a peak output voltage rating of 250 Vdc through
1000 Vdc to be rated for a higher voltage output isolation.
Improved isolation is achieved by a novel output stage with
improved controller isolation. In addition to being able to
fl oat the power supply to a higher output voltage, this option
also enables lower voltage units to connected series up to the
higher isolation rating.
The table below provides the output isolation rating for all
available confi gurations, where Vo is the unit’s rated maxi-
mum output voltage.

High Slew Rate Output
Option Code: +HS
Products Supported: XR Series, TS Series, MS Series, MT Series
The high slew rate option solves several limitations inherent in switching power supply design. Rapid voltage transitions
require internal electronics to supply the energy to charge and discharge output capacitors. Peak currents internal to the
power supply defi ne slew rate; utilizing less capacitance enables voltage transitions in shorter time periods. Additionally,
less capacitance reduces requirements for discharge demands during open circuit conditions.
The standard output stage Magna-Power Electronics power supplies has been designed to provide the lowest possible output
ripple voltage within the constraints of available components, size, and cost. Part of the output stage consists of a bank of
aluminum electrolytic capacitors which has the desired electrical properties to provide this function. These components
require bleed resistors to discharge any voltage when the power supply has no load and is disabled. While the presence of
these components and the resulting performance are normally industry accepted,

there are applications where lower output capacitance is extremely desirable and
higher ripple voltage is acceptable. To meet this need, a high-slew rate option is available which has an output stage consisting of low capacitance fi lm and aluminum elec-
trolytic capacitors. Applications for the high-slew rate option include battery charging, photovoltaic emulation, power waveform generation, and medium speed power
pulsing. These applications all benefi t from higher bandwidth and in many cases, can
tolerate the increased ripple voltage of this option.

UID47: Universal Interface Device
Option Code: +UID
Products Supported: XR Series, TS Series, MS Series, MT Series
Magna-Power Electronics UID47 is a general purpose device for connection to Magna-Power
Electronics’ power supplies. The device contains the necessary circuitry for confi guring power
supplies for master/slave parallel or series operation.
Master/slave parallel operation allows two or more power supplies to equally share output
current when connected together. Master/slave series operation allows two or more power
supplies to equally share output voltage when connected together. In either operation mode,
the master unit will command the slave units to the proper voltage and current. Each unit will
display its own individual voltage and current. Installation requires setting jumpers, placing
included 37-conductor cables between the UID47 and power supplies, and wiring the power
supply outputs in either parallel or series.
The UID47 can be used as an interface for connecting control and monitoring lines to external
circuitry. It also contains an area on the printed circuit board for interconnecting wires and
placing components for specifi c user applications.
Key features of the UID47 option are as follows:
• Compatible with all Magna-Power Electronics power supplies
• Interface for series and parallel master/slave operation
• User confi gurable screw terminal connector
• Pad area for custom circuitry
• (2) 6-foot 37-pin cables included
Water Cooling
Option Code: +WC
Products Supported: TS Series, MS Series
Water cooling is available for Magna-Power Electronics TS Series and MS Series power supplies typically for use in corrosive environments, such as electroplating applications or in densely packaged system cabinets, where heat removal by air
cooling presents a problem.
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 TS Series models have enclosures without vent holes and are basically sealed the unit from the
environment. An internal solenoid valve enables water fl ow when the chill plate reaches 60 degrees celcius. Operation of the
solenoid prevents internal condensation.

one power supply, plumbing connections must be paralleled;
that is, water should not fl ow from one power supply into
another.

RS-485DSS
Option Code: +RS485
Products Supported: XR Series, TS Series, MS Series, MT Series
Certifi ed to the LXI Standard (Class C), the TCP/IP Ether-
net option includes an embedded web-server, allowing web
browser power supply control and monitoring from virtually
anywhere. LXI is an instrumentation platform based on
industry standard Ethernet technology designed to provide modularity, fl exibility, and performance to small- and
medium-sized systems.
LXI’s advantages are exemplifi ed in its compact, fl exible
package providing high-speed I/O and reliable measurements. The Magna-Power Electronics LXI TCP/IP Ethernet
option includes an embedded web-server, allowing web
browser power supply control and monitoring from virtually
anywhere.
The 485DSS allows non-addressable, “dumb” RS-232
devices to be connected on an addressable RS-485 network.
The master node controls all communications to connected
devices. By distributing the switching intelligence along the
RS-485 network, wiring cost savings are substantial compared to a single switched “star” confi guration.
Devices can either be polled by the master node or request
access to the bus through a RS-232 handshake line. This
provides a versatile system for interconnecting devices that
are designed for point to point communications. Because
the units communicate using standard RS-485 signals,
RS-232 devices can form their own network or be added to
an existing system. Up to 32 nodes at up to 4000 feet can be
on one bus without a repeater, and the 485DSS’s addressing scheme allows up to 256 units on a single network with
repeaters.
