MegaEIS™ ME-2SP200

The MegaEIS™ ME-2SP200 is a unique high-power hybrid workstation that integrates a precision Potentiostat Core (PTC) module into the robust MegaEIS architecture.

Engineered for advanced single-cell and short-stack research, it delivers up to 200 A of stable current. Crucially, its dual-mode operation provides a true bipolar ±5 V range in PTC mode alongside standard 0...5 V source capabilities, enabling highly sensitive zero-crossing electrochemical techniques traditionally limited to low-power laboratory instruments. This allows researchers to execute precision cyclic voltammetry, chronoamperometry, and true parallel EIS on large-format cells under heavy operational loads without compromising signal integrity.

Key Features

• Hybrid architecture: Integrates a precision Potentiostat Core (PTC) for advanced large-format single-cell and short-stack R&D.
• Dual-mode voltage range: Operates at ±5 V in PTC mode (enabling full zero-crossing techniques) and 0...5 V in high-power Source mode.
• Maximum current up to 200 A
• Maximum internal power dissipation up to 1 kW
• Advanced electrochemical methods: Execute high-current Cyclic Voltammetry, Chronoamperometry, and Linear Sweeps natively.
• 2× dedicated EIS channels for high-resolution impedance spectroscopy under continuous load.
• High-precision current sensing: Artifact-free data acquisition of both DC and AC components.

Deployment Scenarios

• High-Current Cyclic Voltammetry: Execute advanced electrochemical characterization on large-format industrial cells. The integrated PTC module enables precise cyclic voltammetry and linear sweeps at up to 200 A, allowing researchers to analyze catalyst activity and redox reactions on massive active areas that standard lab potentiostats cannot drive.

• Large-Format Cell Validation: Bridge the gap between fundamental material science and industrial application. Drive single large-format cells or small short stacks natively with up to 200 A while capturing artifact-free, high-resolution EIS data to pinpoint membrane degradation or mass transport limitations under true operational stress.

• Complex Electrochemical Sequencing: Automate demanding test protocols securely. Seamlessly link standard high-power load profiling with advanced potentiostatic methods—such as double-step chronoamperometry or custom polarization sequences—capturing transient responses with the strict precision required for advanced R&D.
