Programmable electronic DC loads » ELP/DCM Series 150 - 300W

For specifications other than those listed below, please contact us via

The ELP/DCM series is a programmable electronic DC load with high resolution and accuracy. The 16-bit A/D and D/A converters provide a voltage resolution
of 0.1 mV and a current resolution of 0.01 mA with a basic accuracy of 0.03%. The loads can be operated in six high-speed modes and feature
overheating, overvoltage, overcurrent, overpower and polarity reversal protection. The loads offer a variety of functions such as battery test, dynamic test, short-circuit
and more. Optional interfaces allow galvanically isolated communication with a computer for control and data acquisition. The software or an own protocol
can be used for this purpose. The 4-channel VFD screen displays two lines. The loads support remote voltage compensation, multi-data storage
and editing of any waveforms in the list function.
