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.
Finally, an electronic load control mode with no bandwidth constraint.
MagnaLOADs 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. High-power resistor modules are fabricated and rigorously tested. An automated surface-mount production line places components on printed circuit boards for control, auxiliary power, and display circuits. And finally after assembly, products undergo comprehensive test and calibration, followed by an extended burn-in period.
There are many possible configurations for the ARx Series product. Using the following ordering guide and models chart to define the best model for your application.
