Zahner EL1000 Electronic-load



The EL1000 was designed to investigate single cells or complete stacks up to 100 V. Adding an additional external electronic load, the maximum current of 200 A can be raised up to 600 A and the corresponding power from 1000 W to 60 kW.


Due to the limited potential span resulting from the combination of chemical elements or compounds, a huge number of cells have to be stacked to achieve a technical practicable voltage, say for instance 100 V. The EL 1000 was designed to investigate complete stacks, either as stand-alone device under PC control or in combination with a workstation IM6 or Zennium for instance for impedance measurements. Adding an additional external electronic load, the power can be raised up – adding the PAD4 to the controlling workstation, individual segments of the stack can be investigated separately.

The EL-Series potentiostats are controlled by an EPC42, a plug-in module for the Electrochemical Workstations IM6 and Zennium. Each EPC42 can address up to four EL-Series potentiostats. Up to four EPC42 cards can control up to 16 ELs by one IM6/Zennium. Each potentiostat will hold the control parameters from one access to the next one, so that no potential or current disturbances can occur while scanning the potentiostats. If series measurements are performed with more than one EL-Series potentiostat, spectra are taken from all modules in a definable order. The EL-Series is completely integrated into the IM6/Zennium environment. Thus, all acquisition and analysis techniques that run on the IM6/Zennium can be applied with the EL-Series potentiostats as well. The installation of one or more EL-Series potentiostat will upgrade your IM6/Zennium to an even more versatile, high-current electrochemical workstation.

The EL1000 potentiostats can alternatively be controlled by a Windows®-PC. In this case they provide methods, summarized in the table below. They also work as a LabView® virtual instrument under the LabView® software. To implement the EL1000 potentiostats into existing test environment, a supporting DLL is available on demand.

You can control the EL1000 potentiostats in a mixed mode with an IM6/Zennium and a PC in parallel. One of both devices can be connected and disconnected during operation.
