Product information "Programmable DC-Load | WRx Series"

Magna Power WRx Series
Programmable Load / Electronic DC Load
12.5 kW 1Ph, up to 1000 V, up to 130 A, CC, CV, CP, CR, SR, RM

The Magna Load of the WRx series uses MOSFET-based active resistance switching, which enables the series to cover a very wide working range as with classic ohmic loads, but only significantly cheaper. For this purpose, individual switchable load resistors are installed in series with the Mosfet operated in the linear range. The regulation for this is carried out via special digital signal processors. The heat is dissipated via water cooling

The advantage of ohmic loads is reliability and cost per watt for power loss, while the advantage of MOSFET loads is the regulation speed of the power. Active Resistive Technology combines switched ohmic load with MOSFETs, ensures that the product costs can be significantly reduced.
