Magna-Power Electronics XR Series IV was designed from the ground up for high reliability and industry leading 2U (3.5" height) rack-mount power density, with output isolation up to 1000 Vdc for models rated for 1000 Vdc and below. This product series utilizes Magna-Power Electronics signature current-fed power processing, delivering robust power conversion with a high power factor—greater than 0.92 for 3Φ units. Soft-start circuitry on the input minimizes in-rush current to levels below the rated input current. High accuracy programming and monitoring levels allow confi - dence in power supply measurements, eliminating the need for external power meters.

All XR Series IV power supplies come standard with isolated 37-pin external I/O, RS-232, Remote Interface Software, IVI drivers for integration into a variety of programming environments, and modulation capabilities for non-linear output profile emulation. Two front panel types are available for different application requirements. The standard XR Version front panel (pictured in the image above) provides front panel control knobs and calibration, start and stop buttons, and a digital display for voltage and current. The C Version front panel provides a blank display panel, allowing control only from the computer or isolated 37-pin I/O connection.

Electronic Output Stage
The new and novel XR Series output stage utilizes constant power loading under all conditions via an electronic bleed resistance. This electronic bleeder means stability under all operating conditions and faster fall times, without affecting the overall system efficiency.

Fully Configurable
XR Series power supplies can be configured through the front panel for different applications. The power supply can be programmed to have its control functions accessible from the front panel, rear connector, RS-232, optional GPIB, optional USB, or optional LXI-certified Ethernet communications. Sensing can be established at the output terminal of the power supply or through a rear terminal block for sensing at the load. An external interlock can be set to enable operation only when an external connection is made. Even calibration has been simplified with front panel access to calibration digital potentiometers.

Isolated External I/O for Automation
Using the rear 37-pin I/O connector, the XR Series power supplies can be completely controlled and monitored using external signals. The voltage, current, over voltage trip, and over current trip set points are set by applying a 0-10 Vdc signal. Each diagnostic condition is given a designated pin, which reads 5 Vdc when high. In addition, reference 5 Vdc and 10 Vdc signals are provided, eliminating the need for external voltage signals and allowing the use of dry contacts. Also, the power supply features an external interlock, which when enabled, allows the power supply to be tied in with other emergency stop equipment. All these pins are isolated to earth-ground as standard--no additional isolation equipment or options necessary.

Designed for Safety
The XR Series power supplies have extensive diagnostic functions—all of which, when activated, take command to shut down the system. Diagnostic functions include phase loss, excessive thermal conditions, over voltage trip, over current trip, fuse clearing, and program line. Program line monitors externally applied analog set point signals to insure they are within the specified range. Upon a diagnostic fault condition, main power is disconnected and the diagnostic condition is latched into memory. Pressing the clear key clears the memory. All diagnostic functions can be monitored through a rear connector. Furthermore, control functions can also be set through the rear connector to allow simultaneous control of one or more XR Series units. XR Series supplies have three levels of over voltage/current protection: shutdown of controlling insulated gate bipolar transistors (IGBTs), disconnect of main power, and input fuses. After an over voltage/current trip condition, the supply must be reset.

XR Version Standard Front Panel
XR models provide stepless analog control from front panel potentiometers. With a simple configuration change, the power supply can be programmed from the rear I/O connector or through software on one of the communications bus. The XR Series has 100 memory states available to program voltage, current, over voltage trip, over current trip, and time period in software. More Info >> 

XRC Version Front Panel
XRC models only allow control from the rear connector or by RS-232/GPIB/Ethernet communications. These models are intended for process control applications where front panel controls and displays are not required or desired. More Info >


Magna-Power SoftwareRemote Interface Software
The Remote Interface Software (RIS Panel) ships with all XR Series power supplies. The software provides the user with a quick method to operate a Magna-Power Electronics' power supply under computer control. The Remote Interface Software has six windows: the Virtual Control Panel, Command Panel, Register Panel, Calibration Panel, Firmware Panel, and Modulation Panel. The Virtual Control Panel emulates the front panel of the XR Series power supply, the Command panel programs and reads SCPI commands with user friendly buttons, the Register Panel programs and reads registers, the Calibration Panel enables calibration of the digital potentiometers, the Firmware Panel enables the program stored internal to the power supply to be upgraded, and the Modulation Panel eases programming of modulation parameters.

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.
