At AlphaOmega-Electronics you will find the best range of Fuel Cell Test Systemand at the most competitive prices.



The EL20W-U is perfectly suited for testing fuel cells and battery cells up to 3 cells connected in series.
Designed for efficiency and fast setup, the EL20W-U connects to a PC as standard configuration through USB cable. All controls are achieved with the user-friendly software interface. The included EZ-Chem software allows a rapid grasp of the main functionalities and fast setup of experiments by new users.

One of the key functions is the cell temperature monitoring integrated to the eLoad. The inclusion of cell temperature measurement together with voltage and current in the same data log makes the EL20W-U ideal for fuel cell and battery testing.
Test data is displayed in real time through convenient graphs and numerical values. Test runs can be set by changing the parameters on-the-fly or by sequence programming. The user has a choice of ramps, steps or automatic polarization curves to set long runs with advanced cycling.

Multiple loads can be connected to a single PC in order to minimize test environment footprint and investments.
The EZ-Chem software is regularly updated with new functionalities that come free for all EL20W-U owners.
