APPENDIX B – CONDUCTIVITY WITH INTEGRATED UV-LED ANTIFOULING
B.3 POWER CONSUMPTION AND BATTERY ENDURANCE
The presence of the UV-LED antifouling system increases the power consumption of the OCEAN
SEVEN 304Plus. The power consumption can be resumed as follows:
CTD at wake-up, sterilization, UV ON
CTD running, measurement,
Considering a typical cycle of 5 seconds dedicated to the UV sterilization only, 4 seconds to carry out
the measurement and sterilization and 2 seconds spent during the wake-up and shutdown functions,
it is possible to calculate the following battery endurance with a 3.6V "C" type, 8.4 Ah battery:
