Batteries and Power
All WorkHorse tests and operations work equally well using internal battery
packs, external battery packs, or the AC power adapter.
7.1
AC Adapter
The AC Adapter runs on any standard AC power and supplies 24 VDC to
run the WorkHorse when the batteries are not connected. Substitute your
own power supply with a voltage of 45 to 60 VDC to override the 42 VDC
alkaline battery packs.
NOTE. The 24 VDC AC adapter does not override the battery voltage!
NOTE. If you collect data using the AC adapter, the profiling range is
reduced compared with standard battery voltage.
NOTE. Transmitted power increases or decreases depending on the input
voltage. A fresh battery provides +42 VDC. Batteries spend most of their
life at a nominal voltage of +33 VDC.
The transmitted power is decreased 1 DB if the input voltage drops from 42
VDC to 33 VDC. For a 300kHz WorkHorse ADCP, each DB will result in a
decrease in range of one default depth cell.
7.2
Alkaline Battery Pack Capacity
RDI specifies its battery packs to have 400 watt-hours (Wh) of usable en-
ergy at 0°C.
7.3
External Battery Pack
The External Battery Pack holds two 400 watt-hours (Wh) batteries. To
avoid affecting the compass, place the external battery case at least 30-cm
away from the Sentinel WorkHorse.
