High Power DC Electronic Loads
Active Resistance + Microchannel Water Cooling
Utilizing Magna-Power’s new patent pending Active Resistance Technology in combination with the company’s internally manufactured microchannel water-cooled heatsinks, the WRx Series addresses high power DC applications where exhaust heat control is essential. The WRx Series greatly increases power density compared air-cooled alternatives. An integrated solenoid controls the flow of water to avoid condensation. Full power can be achieved using conventional water, with water inlet temperatures up to 25 °C.
Magna-Power's Active Resistance heat dissipation technology utilizes a switched binary matrix of resistances and MOSFET network, combined with Magna-Power's new MagnaLINK™ distributed DSP architecture, the WRx 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 WRx Series also provides a rheostat control mode, allowing direct control of the product's internal resistance network.
Designed and Manufactured in the USA, Available Worldwide
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 WRx Series product. Using the following ordering guide and models chart to define the best model for your application.
