AC/DC POWER SUPPLY
This provides an isolated 13.65 V DC output for powering of the load
and charging of the battery. Battery current is sensed and monitored by
the power supply to limit the charging current to 15 A or 30 A maximum
depending on the model. Refer to About the Genius-II Power Supply.
FAULT PROTECTION
The power supply provides automatic protection for overload including short
circuit, over-voltage, over-temperature and reverse connected battery.
In overload, short circuit, and over voltage condition the power supply will
shut down. It will then automatically attempt to restart every 5 seconds until
such case that the fault is removed.
FUSING
Each load circuit and the caravan battery connection have been fused to
provide fault protection and discrimination. Refer to the servicing section for
fuse ratings.
BATTERY CHARGING FEATURES
The power supply (Genius-II) provides full battery management as per the
following: The power supply is a three stage battery charger with Boost,
Float, and Store charging modes to ensure long battery life. Charging
current is limited to a maximum of 15 A or 30 A maximum depending on the
model. Details of the charging process can be found in the Battery Charging
Management section below.
The power supply is able to deliver 35 A maximum to the battery and
loads on all models. For GENIUS-II, GENIUS-IIA and GENIUS-IIN, the 15 A
battery charging rate is only possible if the load current is 20A or less. If the
load current exceeds 20 A, the maximum battery charging current will be
reduced accordingly. The same logic goes for GENIUS-IIH, GENIUS-IIHA and
GENIUS-IIHN models, but have maximum battery charge current of 30 A.
Note that for the Genius-II to operate in the manner described above, all
loads must be connected to load terminals, not directly to the caravan
battery.
Low Voltage Disconnection of the batteries is provided to prevent deep
discharge of the battery. Automatic reconnection occurs when battery
voltage recovers. Battery Current Drain is less than 3 mA.
