The EL3008-0003 is designed for measuring stacked voltages up to 1000 V CAT II, such as those found in accumulators and fuel cells. The negative pole of one cell is also the positive pole of the next. In combination with the high galvanic isolation to the E-bus, these terminals can be used to record large cell stacks with minimal wiring. This allows cell behavior to be monitored during normal operation and facilitates rapid responses in case of malfunctions.
