These cables establish current limiting (2 ma target limit, 2.2 ma maximum) over a compliance voltage range of ±200 volts and are primarily used with the STMISOLA for tDCS and tACS stimulation as a safety precaution.
- CBLLIMIT2 for unipolar current limiting
- CBLLIMIT2AC for bipolar current limiting
The CBLLIMIT2 cable will permit any unipolar current between 0 and 2 ma to pass. The CBLLIMIT2AC cable will permit any bipolar current between 0 and ±2 ma (p-p) to pass.
The CBLLIMIT2 and CBLLIMIT2AC current limiting cables are factory tunable for a range of current limits (typically 1-20 ma) and may have other uses where a current limit is required, such as during general purpose electrical stimulation protocols. These current limiters can be set to ensure that dangerous current levels are avoided, despite possible system errors.
