Serie XR Fuente de Alimentación CC Programable
The XR Series was designed from the ground up for high reliability and industry leading 2U (3.5” height) rack-mount programmable power levels, at: 2 kW, 4 kW, 6 kW, 8 kW, and 10 kW. The XR Series features the largest voltage range in Magna-Power's product offering, from 5 Vdc to 10,000 Vdc, all utilizing the company's signature current-fed power processing to deliver robust power conversion. In addition, high accuracy programming and monitoring levels allow confidence in power supply measurements, eliminating the need for external power meters.
Overview
Fully Programmable DC Power
The XR Series features programmable voltage, current, and protection settings along with high accuracy measurements. The XR Series functions and features are accessible and configurable from a variety of control methods, including:
- Front panel interface with stepless knobs
- 37-pin isolated analog-digital user I/O
- RS232 Computer interface with software and drivers
Various additional programming interfaces are available, such as LXI TCP/IP Ethernet (+LXI), IEEE-488 GPIB (+GPIB), Edgeport USB Accessory (+USB), RS485 Accessory (+RS485).
Designed for Safety
XR Series power supplies have extensive diagnostic functions, including:
- AC Phase Loss
- Excessive Thermal Conditions
- Over Voltage Trip (Programmable)
- Over Current Trip (Programmable)
- Cleared Fuse
- Excessive Program Line Voltage
- Interlock Fault
When in standby or diagnostic fault, the AC mains are mechanically disconnected by an embedded AC contactor, providing confidence that the unit is only processing power when desired.
Finally, with a dedicated +5V interlock input pin and included +5V reference on all models, external emergency stop systems can be easily integrated using an external contact.
Extensive Programming Support
All XR Series MagnaDC power supplies come with a dedicated National Instruments LabVIEW™ driver, Interchangeable Virtual Instrument (IVI) driver, and support for a wide range of Standard Commands for Programmable Instrumentation (SCPI). These programming interfaces support full control, measurement, and monitoring of the MagnaLOAD. All of the MagnaLOAD's available communication interfaces are supported by these drivers and command sets, including: RS232, LXI TCP/IP Ethernet, IEEE-488 GPIB, USB or RS485.
Showcased in the following basic code examples, SCPI commands provide the simplest form of communication by using plain ASCII text and parameters sent over a basic socket connection. Over 50 commands are provided, with detailed documentation in the XR Series User Manual.
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

Current-Fed Topology: Robust Power Conversion
All MagnaDC programmable DC power supplies utilize high-frequency IGBT-based power processing in current-fed topology. This topology adds an additional stage over the conventional voltage-fed topology for enhanced control and system protection, ensuring that even under a fault condition, the power supply will self-protect. Due to the self-protecting characteristics of this topology, the possibility of fast rising current spikes and magnetic core saturation is eliminated.
In addition to its robust topology, key performance characteristics of MagnaDC programmable DC power supplies include:
- High-accuracy voltage and current programming accuracy
- Class-leading line and load regulation performance
- High 3Φ AC input power factor with in-rush limiting circuitry
- Computer and user I/O isolated from the power supply output

Designed and Manufactured in the USA, Available Worldwide
For complete control of quality, MagnaDC programmable DC power supplies are designed and manufactured at Magna-Power's vertically integrated USA manufacturing facility in Flemington, New Jersey. Heat-sinks and chassis are machined from aluminum. All sheet metal is fabricated and powder coated in-house. Magnetics are wound-to-order from validated designs based on a model's voltage and current. An automated surface-mount production line places components on printed circuit boards for control, driver, auxiliary power, and display circuits. And finally after assembly, products undergo comprehensive test and calibration, followed by an extended burn-in period.
Models
There are 136 different models in the XR Series spanning power levels: 2 kW, 4 kW, 6 kW, 8 kW, 10 kW.
