    MagnaLoad DC Electronic Loads
    Finally, an electronic load control mode with no bandwidth constraint
    Magna-Power's patent pending Active Resistance Technology is a completely new approach to electronic loads. By utilizing a switched binary matrix of resistances and MOSFET network, combined with Magna-Power's new MagnaLINK™ distributed DSP architecture, the ARx Series delivers the same features and performance as traditional electronic loads, at a fraction of the price. Beyond voltage, current, resistance, and power control modes, the ARx Series also provides a rheostat control mode, allowing direct control of the product's internal resistance network.

    MagnaLINK™ Distributed DSP Architecture
    Magna-Power's MagnaLINK™ technology provides distributed Texas Instrument DSP control across power processing stages inside the MagnaLOAD DC electronic load. This technology follows a significant internal development cycle from Magna-Power to provide a unified digital control platform across its electronic loads and power supplies, featuring fully digital control loops, adjustable control gains, programmable slew rates, function generation, and many new advanced control technologies.

    Many Control Modes
    To accommodate a variety of DC sources, all ARx Series MagnaLOADs come with several distinct control modes, including: Voltage Mode, Current Mode, Power Mode, Resistance Mode, Shunt Regulator Mode, and Rheostat Mode. Preference for DC regulation is given to the parameter in the selected mode within the programmed set-points. Using the MagnaLOAD's set-points and trip settings, the product can configured to either trip with a fault when a limit is exceeded or to cross-over into a different regulation state.

    Shunt Regulator Mode turns the MagnaLOAD into a high-speed smart braking resistor, engaging the DC input only when a specified voltage is exceeded by a user-defined percentage, while limiting the shunt current to a programmed set-point.

    Rheostat Mode, unique to the ARx and WRx Series, bypasses the digital controls to provide direct control of the MagnaLOAD's internal resistor network. Using this mode, true resistance step load response can be achieved without the traditional bandwidth limitations. While the standard operating modes offer 16-bit programming resolution, Rheostat Mode provides 31 different resistor states.

    Integrated Arbitrary Waveform Generation  (This is planned feature, and will be available via a future firmware update.)
    All MagnaLOADs provide four user programmable arbitrary waveforms. Each arbitrary waveform can consists of up to 1024 points, each point with the following settings:

    • Voltage, Current, Power, and Resistance Set Points
    • Time Period
    • Rise and Fall Slew Rates
    • Stop, Loop, or Jump-to-Point Setting

    With the integrated arbitrary waveform generation, the MagnaLOAD can easily be used to provide a wide range of user-generated waveforms including step load transitions or pulsed DC loading.

    MagnaLINK™ Distributed DSP Architecture
    Magna-Power's MagnaLINK™ technology provides distributed Texas Instrument DSP control across power processing stages inside the MagnaLOAD DC electronic load. This technology follows a significant internal development cycle from Magna-Power to provide a unified digital control platform across its electronic loads and power supplies, featuring fully digital control loops, adjustable control gains, programmable slew rates, function generation, and many new advanced control technologies.

    Digital Master-Slaving: Expandibility Without Compromise  (This is planned feature, and will be available via a future firmware update.)
    All MagnaLOADs come standard with a MagnaLINK™ Input and a MagnaLINK™ Output port, which provides plug and play digital master-slaving. Simply connect the master's MagnaLINK™ Output to the slave's MagnaLINK™ Input and the MagnaLOADs will automatically configure themselves for master-slave operation based on the populated ports. Buffered digital MagnaLINK™ connections means many MagnaLOADs can be daisy-chained in master-slave operation.

    Extensive Programming Support
    All ARx Series MagnaLOADs 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: USB, RS485, LXI TCP/IP Ethernet, and IEEE-488 GPIB.

    Configurable External User I/O
    Beyond the front panel and computer controls, all MagnaLOADs come standard with a 25-pin D-Sub completely-configurable connector designated as the External User I/O. This connector provides:

    • 8 Digital Outputs
    • 4 Digital Outputs
    • 4 Analog Outputs
    • 4 Analog Inputs

    Note: The power rating determines the maximum available current for a given voltage output. For example, the ARx6.75-1000-14 is rated as 1000 V, 14 A, or 6,700 W, but you cannot get 1000 V and 14 A simultaneously. The maximum current at 1000 V is 6.75 A (1000 V x 6.75 A = 6,750 W).
