Underwater sound measurements in the field often require hydrophones with built-in preamplifiers or they are connected to conditioning amplifiers that requires portable DC voltage supply.
The EC6069 Battery Module supplies 18VDC from two exchangeable dry cell batteries. EC6069 is an ideal DC voltage source for hydrophones and for the preamplifiers VP1000 and CCA1000.
The EC6069 consists of a sealed EMI/RFI shielded aluminum case that encloses 2 x 9 Volt Alkaline batteries type IEC 6 LR 61 9Volt 0.55ah.
