XR SERIES II
Rugged Current-Fed Technology
Innovative and Scalable
Magna-Power Electronics XR Series combines the best of
DC power processing with microprocessor embedded control.
Magna-Power Electronics’ innovative power processing tech-
nology 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. This technology allows the power supply to operate
under short-circuit conditions, open-circuit conditions, and
everything inbetween.
XR Series power supplies offer both master/slave paral-
lel 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 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.
Attention to Power Quality
XR Series power supplies contain circuitry to work harmo-
niously 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.
