INTRODUCTION
MB-3622 intelligent battery charger with 12-bit AD
microprocessor
– Charges with 12 V, 15/10/2 A DC (22/15/3 A RMS)
– Self-identifying multi-stage characteristic charging curve
Soft Start tests the battery condition. Severely discharged
batteries need the soft start step. The charging starts with a
reduced current until the voltage reaches 10V.
Bulk is the main step where most of the charge is returned
(60-80%). The charger delivers maximum current until the
terminal voltage has risen to the set level of 14,2V for Normal
battery selection and 14.0V for Gel battery selection and 14.4V
for Deep Cycle battery selection.
Absorption completes the charge up to virtually 100% at a
constant voltage. The current tapers off after the current reached
the minimum level.
Float is maintenance charge at constant voltage, keeping the
batteries at 100% charge. Normal charging mode is time-limited
(max 10 days) while Supply mode goes on indefinite without
damaging the battery.
Pulse is maintenance charge for maximum battery life. Charging
varies between 80% and 100% state of charge. The battery
receives a pulse, starting a new charge cycle, when voltage drops
to set limit. This keeps the battery in perfect condition when it is
not in use. The charger can be connected for months keeping the
batteries fresh.
