Magna-Power Arx Series

DC Electronics Loads, 6.75 kW, Up to 1000VDC, Up to 140 ADC

The ARx Series MagnaLOAD uses Magna-Power’s patented Active Resistance Technology (US Patent 9,429,629), 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. In addition to 16-bit precision voltage, current, resistance and power control modes, the ARx Series also provides a rheostat control mode for direct control of the product’s internal resistance network; finally an electronic load control mode with no bandwidth constraint for true step load response. This novel power dissipation strategy with state-of-the-art digital control provides an electronic load solution like none other on the market.
