The new series of electronic DC loads with energy recovery to mains, called EA-ELR 9000, offers new voltage, current and power ratings for a multitude of applications. These devices incorporate the four common regulation modes constant voltage, constant current, constant power and constant resistance. The FPGA based control circuit provides additional features, such as a function generator, a table based regulation circuit for the simulation of non-linear internal resistances. The energy recovery function converts the supplied DC energy into a synchronous sine current and feeds it back into the local grid. This eliminates the usual heat dissipation to a minimum and saves energy costs at the same time. The large colour TFT touch panel offers a different and intuitive kind of manual operation, compared to other devices. Response times for the control via analog or digital interfaces have been improved by the DSP controlled hardware. In parallel operation of multiple devices, a master-slave bus is used to connect the units to a bigger system where the actual values are totalled and the set values distributed.
