EL-Series

Power potentiostats and electronic loads today are indispensable tools in several fields of electrochemistry, for example in the research of fuel cells. The potentiostats of the EL series are designed to sink high currents up to 100A/25A at a total power dissipation of up to 300W/100W (EL300/EL101). Both modules may be connected in full cell or half cell schemes. Using an additional external power supply you easily can extend an electronic load of the EL series to a two-quadrant potentiostat, you need for example in the field of electrolysis.

The EL101/300 is controlled by an EPC42, a module which is plugged into an extension slot of the IM6 or ZENNIUM. Each EPC42 can address up to 4 PP/XPot/EL modules. Up to 4 EPC42 cards can be installed in an IM6 or a ZENNIUM system. In total, an IM6 and a ZENNIUM is able to control up to 16 EL101/300 devices.

Each potentiostat will hold all its values from one control 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 module connected, spectra are taken from all modules in a definable order.

The EL series modules are implemented completely in the IM6 and ZENNIUM environment. Thus, all acquisition and analysis techniques that run on these systems can as well be applied with the EL modules. The installation of one or more EL devices will upgrade your IM6 or ZENNIUM to an even more versatile high-current electrochemical workstation.

For connection of an EL device an EPC42 module is required !

FRA-Interface

The FRA module is designed to interface third-party potentiostats and electronic loads (external devices) to the IM6 or ZENNIUM system. The external device must provide an analog control input and analog signal outputs for the measured current and voltage. FRA is fully supported by the Thales software. Only the gain factors have to be set for each external device individually.

The control signal provides both, the DC signal controlling the DC current or voltage of the external device and the AC signal necessary e.g. for EIS measurements.
