These cables establish current limiting (2 ma minimum, 3 ma maximum) for a compliance voltage range of ±200 volts, and are primarily used with STMISOLA for tDCS stimulation as a safety precaution.
- CBLLIMIT2 for unipolar current limiting
- CBLLIMIT2AC bipolar current limiting
The CBLLIMIT2/2AC cable will permit any unipolar current between 0 and 2 ma to pass. If more than 2 ma is attempted to be injected through the cable, then the compliance voltage across the CBLLIMIT2/2AC will rapidly rise, thus constricting current flow. When used in conjunction with the STMISOLA, the maximum current that can be injected through the CBLLIMIT2/2AC is 3 ma, as this current will result in the CBLLIMIT2/2AC hitting the 200 V compliance limit of STMISOLA.
The cable is factory tunable for a range of current limits and may have other uses in situations where a maximum current limit is required. See More...
