HARACTERISTICS
•
Bulk Charge
- this is initiated at power up and
provides the chargers full-rated current to the
battery bank until a predetermined voltage level
of 14.2V to 14.4V is achieved and/or a certain
time has passed.
•
Absorption Charge
- this stage immediately
follows the bulk charge mode. It maintains the
battery voltage at the bulk charge voltage level,
but gradually decreases the current as the

HARGERS
The main battery, generator and bow thruster battery
charging units are located on the forward component
board in the utility room. The utility room is accessed
by lifting the galley companionway steps. These
units are fully automatic and designed specifically
for the marine environment. The high frequency
characteristic has allowed these chargers to
achieve a size and weight reduction over their
previously used equipment. Commonly called high
frequency or smart chargers, these units bring a
new sophistication to the battery charger field. These
units feature a built-in amperage indicator and a
dual color power-on LED. When the charger is on
the LED will be RED, indicating charger is in fast
charge mode. After the absorption cycle is complete
(approx. 3 hours) the LED will change to GREEN,
indicating the charger is in float mode. To verify that
the charger is functioning properly, turn on lights or
other load. The ammeter should register an
increase.

Leave the converter running at all times to

NOTICE
battery accepts the charge until it reaches a
predetermined current level.
•
Float Charge
- this stage is designed to hold
the battery at a safe, low voltage (typically 13.3V)
providing up to the chargers full rated amperage
to accommodate DC load requirements. The
charge will remain in this mode until the AC
power is cycled off and then on again.
