Magna-Power Electronics XR Series combines the best of DC power processing with microprocessor embedded control. A combination of high and medium frequency power processing technologies 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 in between.
XR Series power supplies offer both master/slave parallel 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.
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, RS232, optional GPIB, optional USB, optional IEEE-488, 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.
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 10 Vdc when high. 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 necessary!
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 (IGBT’s), disconnect of main power, and input fuses. After an over voltage/current trip condition, the supply must be reset.

XR models provide stepless analog control from front panel potentiometers. With a simple configuration change, the power supply can also be programmed from the rear I/O connector or through software on one of the communication interfaces.

XR models utilizing the C Version front panel, XRC, only allow control from the rear connector or by RS232, IEEE 488.2 GPIB, LXI TCP/IP Ethernet, USB, or RS485 communications. These models are intended for process control applications where front panel controls and displays are not required or desired.

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 analog signal. Each diagnostic condition is given a designated pin, which reads 5 Vdc when high. 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 necessary!
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. RIS Panel is available for download.
