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 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. This technology allows the power supply to operate under short-circuit conditions, open-circuit conditions, and everything inbetween.

XR Series power supplies oer 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.

GPIB, USB, Ethernet, RS485 interfaces optional

• Optional LXI-certied ethernet communications:

Embedded web-server

Attention to Power Quality

XR Series 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.

• OVT and OCT shutdown standard:

Mechanical contactors disconnect input mains

• Certied LabWindows/CVI, LabView, and IVI Drivers

• Programmable Output Modulation:

Emulates user-dened power proles

• Automatic Voltage/Current Crossover

• Front Panel Calibration
