Cell voltage measurement for fuel cells, electrolysis and redox flow DILICO cell voltage 48 reliably measures up to 48 cell voltages on each individual cell in the stack in 20 ms with a measurement accuracy of up to ± 0.1 mV and is suitable for all common energy converters and storage devices for cell voltages of up to 4.5 V per cell. DILICO cell voltage detects faults and damaging operating conditions in advance due to the adjustable overvoltage and undervoltage limits, thereby reducing and avoiding failure and maintenance costs. The DILICO cell voltage 96 version is available for measuring up to 96 cells. The CAN interface makes it possible to set up a bus system to connect several devices for measuring galvanic elements with more than 96 cells.
