20A/50A/100A Current Booster

& Principle This high-current booster series extends the output capability of a host potentiostat/galvanostat to support demanding electrochemical loads. When paired with a compatible single-, bi- or multi-channel workstation, the booster routes the control signal from the potentiostat and delivers a proportionally higher current to the cell while the base instrument maintains potential control and data acquisition. Available variants raise the current limit to ±20 A, ±50 A, or ±100 A for one channel at a time, enabling accurate potential-controlled experiments on large-area or low-impedance cells.

One booster drives one channel of a bi-/multichannel frame. Base instrument ranges (for context): typical standalone limits are up to ±2 A/±10 V for single-channel units and ±1 A/±10 V per channel for bi/multichannel systems; the booster elevates current capacity while potential control remains with the host. Compliance & voltage: governed by the paired potentiostat; use the booster when higher current is required without compromising potential regulation. Compatibility Optimised for Corrtest workstations across corrosion, materials and battery research. It is routinely combined with single-channel systems or with one selected channel on multichannel frames. Typical Applications Fuel cell component and MEA testing Battery cell/core and pouch-cell experiments Water electrolysis and electroplating at high current density
