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 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. In addition to the 16-bit precision 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. Previous DIGITAL CONTROL OPERATING MODES EXTERNAL USER I/O MAGNAWEB SOFTWARE Next MagnaLINK™ Distributed Digital Control 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, digital master-slaving, and many new advanced control technologies. All ARx Series MagnaLOADs come with the following interfaces: Front panel knob, keypad, and menu system 25-pin configurable external user I/O, including a high-speed analog input Front and rear USB and rear RS-485 or optional Ethernet and IEEE-4888 GPIB When in standby or diagnostic fault, the DC input bus is disconnected via a switching device. Finally, with a dedicated +5V interlock input pin and included +5V reference on all models, external emergency stop systems can be easily integrated using an external contact.
