High Frequency IGBT-based Switch-Mode Design

The XR Series utilizes the latest IGBT devices to drive down size and increase performance. The high frequency design delivers fast transient response and low output ripple. This performance coupled with Magna-Power's rugged current-fed power processing, enables confidence in even the most demanding applications.

Fully Programmable Power

All XR Series functions and features of are available and programmable from a variety of control methods, including:

  • Stepless front panel knobs
  • 37-pin isolated analog-digital I/O
  • Computer interface with software and drivers

Various programming interfaces are available, such as LXI TCP/IP Ethernet (+LXI), IEEE-488 GPIB (+GPIB), Edgeport USB, Accessory (+USB), RS485 Accessory (+RS485).

High 2U Power Density and High Voltage Models Available

The XR Series products delivers up to 10 kW and up to 10,000 Vdc in a 2U (3.5" height) package, while still maintaining the reliability customers have come to expect from Magna-Power. Whether the application demands high voltage or high current, more power levels and models means the XR Series can better target requirements without over-sizing the power supply.

Designed for Safety

XR Series power supplies have extensive diagnostic functions, including: phase loss, excessive thermal conditions, over voltage trip (programmable), over current trip (programmable), cleared fuse, and excessive program line voltage. When in standby or diagnostic fault, the AC mains are mechanically disconnected via an embedded AC contactor, providing confidence that the unit is only processing power when desired.

Scalable Master-Slave Operation

For maximum flexibility, all XR Series power supplies can be scaled a in master-slave configuration for higher voltage or current output. Using the plug and play Universal Interface Device (+UID47), units are tied together in via their 37-pin I/O, allowing an increase in system current when configured in parallel or increase in system voltage when configured in series—up to the power supply's output isolation rating.

Extensive Programming Support and Included Software

All XR Series power supplies come standard with a National Instruments LabVIEW™ and LabWindows™/CVI drivers. In addition, an IVI driver is included supporting Visual C++, Visual C#, Visual Basic .NET, MATLAB, Measure Foundry, PAWS, Visual Basic 6.0, and Agilent VEE Pro. A Standard Commands for Programmable Instrumentation (SCPI) command set is also supported, allowing programming using raw ASCII commands. Finally, Magna-Power's RIS Panel software is provided allowing for a virtual control panel controlling the power supply via any of the available communication interfaces.

Model Ordering Guide

Models Chart

The following chart details the available standard XR Series models. The Current Maximum (Adc) column is separated by the available power levels. To determine the appropriate model, first select your output Voltage Maximum (Vdc) to find appropriate row. Next, select one desired Current Maximum from the row that contains your desired Voltage Maximum. Then, construct your model number according to the model ordering guide, above. Non-standard voltage and current configurations are available.
