ME-130L500x200
ME-130L500x200
The MegaEIS ME-130L500x200 is a robust workstation with an internal power load, specifically designed for fuel cell stack testing. Its modular design allows for the connection of an external booster expanding the system's total power capacity to 40 kW.
With 130 fully synchronized measuring channels, it’s ideal for parallel testing of large stacks — capturing real-time insights into cell uniformity, degradation mechanisms, and efficiency under industrial-scale loads. Delivering up to 500 A, the ME-130L500x200 ensures the stability and control required for accurate impedance and durability tests on large-scale fuel cell stacks.
