Power Source Emulation
Modulation enables the power supply to emulate different sources: such as batteries,
fuel cells, photovoltaic arrays, etc. This emulation is accomplished by programming the
output voltage or current to respond to an input variable using the Remote Interface
Panel or with SCPI commands. The figure on the left illustrates the programmed piece-
wise linear approximation for a typical photovoltaic array. Alternatively, an I-V curve can
be set using LabView using Magna-Power Electronics cerified Labview drivers.

Battery Charging
A temperature compensated battery charger for applications with lead acid batteries. Diode
D1, placed between the power supply and battery, blocks current from flowing from the bat-
tery to the power supply. This eliminates any loading on the battery when the power supply
is off and prevents the battery from charging the power supply’s output capacitors. Remote
sensing should be applied across the battery terminals to compensate for the diode drop. By
setting the voltage and current to the bulk charge voltage and maximum charge current, the
power supply will initially charge the batteries in current mode control and then automatically
crossover to voltage mode control when the batteries reach the desired set point. The power
supply can be programmed for time dependent, sequential step operation to equalize and
float charge the batteries after bulk charging.

Automated Test Equipment (ATE)
High power density and isolated rear I/O make the XR Series
the ideal DC power source for rackmount systems. The
analog I/O port allows you to connect a programmable logic
controller or other external controls to set voltage, current,
trip points, and monitor all the power supply’s diagnostics
using industry standard +5 Vdc signals.
Automotive Drive Testing / Burn-in
Whether for developing hybrid / electric powertrains or
testing and burning-in electric motors, our DC supplies are
proven in the automotive industry. With high current capa-
bilities, transient response, and robust safety features, our
power supplies are applied to a large number of automotive
applications.
Water Treatment, Electrolysis, and Chemical Processes
Low ripple, excellent controls, and high reliablilty make the
XR Series a solid choice for applications in electrodeioniza-
tion (EDI) and electrolysis. Our supplies can be found around
the world powering EDI modules. For hydrogen produc-
tion, high efficiency and advanced diagnostics make the XR
Series a smart choice.
Research at Universities and National Labs
Magna-Power Electronics’ products can be found in research
facilities, universities, and national laboratories around the
globe. Our wide range of output voltages, robust current-
fed power processing technology, and committment to our
customers and their applications have differentiated us from
the competition.
