Sentinel 150P installation, operation & maintenance ci0050 p3/8 issue 5 2014-08-26
BEFORE BEGINNING INSTALLATION OF THIS PRODUCT
Disconnect all electrical power to the charger
Make sure the charger cannot operate during installation
Follow all safety warnings of the battery manufacturer
Read and follow all installation instructions
WARNING
Sentinel 150P battery chargers provide new levels of DC
power control, monitoring and protection for engine
starting and standby battery applications. Computronic
advanced charger features included as standard:

Switch mode charging technology: high power
efficiency and low heat dissipation, plus wide supply
voltage tolerance, in a compact and lightweight package.

Multistage charging: float, bulk, absorption and
AutoBoost stages ensure no compromise between rapid
charge recovery and long term battery capacity and life.

Low output ripple: <1% ripple, beneficial for vented
lead acid & NiCd cells, essential for VRLA, and
configurable for use as a stand-alone DC power supply.

AutoBoost: triggered automatically on low battery
voltage levels, or by a programmable interval timer,
AutoBoost temporarily increases the charge voltage to
give battery cell charge equalization, without overcharge
and gassing. At the end of the AutoBoost cycle,
Sentinel automatically returns to float mode charging.
AutoBoost maximizes battery power, capacity and
service life.
On SNTL150P..CDA models, a programmable input can
be configured to activate AutoBoost, regardless of
battery voltage. The input is typically triggered using an
operator-initiated panel push-switch.

Temperature compensation: ensures batteries are
charged at the optimal voltage, which varies
significantly with ambient temperature. Sentinel can
measure temperature with a battery mounted sensor,
and adjust output voltage to prevent under or over
charging.

PC software tool: allows flexible, custom
configurations, plus real time monitoring and
diagnostics. See page 6 for details of Sentinel to PC
hardware connection, or separate document ci0052 for
information on software installation, operation and
program options.
All Sentinel 150P chargers are available as an open-
frame module (with protective cover) for surface mounting
in an enclosed panel. Electrical connection of the AC
supply, battery and control circuits is via screw terminal
blocks.
Model options
Model codes with suffix 'A' (SNTL150P.... CDA)
additionally include an input for charger control and an
output for remote signalling of alarm conditions.
Both input and output functions are programmable using
the SNTL150P-PCSUITE software tool. See Configuration
section for a list of programmable input and output
functions.
