3.2 Battery Charger
The PSU incorporates an intelligent three-
stage battery charger / power converter.
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.
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, with the leisure load taking
priority as per the following example:
Leisure load Available power for
battery charging
5A 20A
10A 15A
15A 10A
20A 5A
WARNING: Under heavy loads the PSU
case may become hot. ALWAYS ensure
the ventilation slots have a clear flow of
air. Do not place combustible materials
against / adjacent to the PSU.
3.3 Smart Charging
The system incorporates a smart charge
feature, which monitors both leisure and
vehicle batteries and automatically adjusts
and directs the charger power (and solar
power if a solar panel is installed) to
maintain the leisure and vehicle batteries
at an optimal level.
3.4 Leisure Battery
A) Type / Selection
For optimum performance and safety it
is essential that only a proprietary brand
LEISURE battery is used with a typical
capacity of 75 to 120 Ah (Ampere / hours).
AnormalcarbatteryisNOTsuitable.This
battery should always be connected when
the system is in use.
The PSU 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. Before fitting non-
standard batteries please check that the
charging profile described in 3.2 is suitable
for the type of battery by referring to
the battery documentation or battery
manufacturer.
