ELR 91000-30 Datasheet
The Intepro Systems ELR 91000-30 Electronic DC Load with Energy Recovery 1000V, 30A is part of the new Intepro ELR 9000 series. This devices incorporates the four common regulation modes constant voltage, constant current, constant power and constant resistance. The FPGA based control circuit provides additional features like 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 or public grid. This eliminates the usual heat dissipation to a minimum and saves energy costs at the same time.

The large LCD touch panel offers a modern and intuitive user interface. The ELR 91000-30 offers four operating modes, Constant Voltage (CV), Constant Current (CC), Constant Power (CP) and Constant Resistance (CR). 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 chassis to a create high power system where the actual values are totalled and the set values distributed.
