PX300 – 300Watt, 3-Stage Battery Charger
During stage 1 the battery voltage is increased
gradually while the current is limited to start the
charging process and protect the battery. At
stage 2 the voltage rises to 14.4V to deliver the
bulk charge to the battery. When the battery
is charged, the voltage is decreased at stage
3 to 13.6V to deliver a float charge to maintain
the battery in the fully charged state. The
charger can be left switched on continuously as
required.
WARNING: Under heavy loads the Battery
Charger case may become hot. ALWAYS
ensure the ventilation slots have a clear flow
of air. Do not place combustible materials
against / adjacent to the charger.
Leisure Battery
Type / Selection
For optimum performance and safety, it is
essential that only a proprietary brand LEISURE
battery is used and it is suggested to select a
battery from the NCC Verified Battery Scheme
with a typical capacity of 75 to 180 Ah (Ampere
/ hours). Depending on the prospective use of
the vehicle the correct type should be selected
(A, B or C). A normal car battery is NOT suitable.
This battery should always be connected when
the system is in use.
The MC100 is configured to work with standard
lead acid leisure batteries, and in most cases
is also compatible with the latest range of
Absorbed Glass Matt (AGM) batteries. The
The battery charger / power converter also
provides power to the leisure equipment when
the mains supply is connected. This module
supplies DC to the leisure equipment up to a
maximum of 25 Amps (300 Watts), therefore
the available power is distributed between the
leisure load and the battery.
system is also suitable for Lithium batteries
with built-in Battery Management Systems
(BMS) such as the Sargent Lithium+ Series.
Before fitting non-standard batteries please
check that the charging profile is suitable for
the type of battery by referring to the battery
documentation or battery manufacturer.
Some vehicle installations can cater for two
leisure batteries connected in parallel. In these
cases, it is recommended that two identical
batteries are used.
The leisure (and vehicle) battery feed should
be protected with an inline fuse between the
battery and the electrical harness, and this
fuse should be located immediately outside the
battery compartment or within 500mm of the
battery. The recommended fuse rating is 20A
per battery.
