Power Supplies
MAWS is a low-power system. The QML102 logger consumes only
less than 10 mA from a 6 V battery. It can be powered using a solar
panel or optionally in fixed installations using a 110/230 AC power
supply. Also primary lithium or alkaline cells (6 ... 9 V) as well as
external DC supply (8 ... 14 VDC recommended, 30 VDC max) alone
can be used as the main power source for MAWS.
