CS2020B 20A Current Booster High Current High Power Potentiostat

20A Current Booster High Current High Power Potentiostat

CS2020B Current Booster

Single-channel potentiostat (CS350M/ CS310M/ CS300M etc) can achieve maximum±2A/10V output when it’s used alone. This value is ±1A/10V for each channel of bipotentiostat (CS2350M/CS2150M) and multichannel potentiostat (CS310X).

A current booster CS2020B can be connected to single-, bi-, or multi-channel potentiostat to boost the current (up to 20A). Please note that one set CS2020B can boost only one channel of bi- / multi-channel potentiostat.

When not connected the booster, the potentiostat can also be used alone.
