Power Components
Internal Power
The Aqua TROLL Instrument operates on 3.6 VDC, supplied by a
sealed, non-replaceable AA lithium battery. Battery life depends
on sampling speed. The battery typically lasts for 5 years or
200,000 readings, whichever occurs first. One reading is defined
as date, time, and all available parameters polled or
logged from the device.
External Power
External Battery Pack
The sealed, submersible TROLL Battery Pack (lithium)
supplies 14.4 V. When this power source is connected,
the Aqua TROLL Instrument will use the external battery
source first and switch to the internal batteries when
external battery power is depleted. Typical external
battery life when logging all available parameters at
2-minute intervals is approximately 2 years.
AC Adapter
In-Situ’s AC adapter provides 24 VDC, 0.75 A, AC input 100-
250 V, includes North American power cord. The Programming
Cable includes an external power input for connection to this
adapter.
