CHARGER
The NE143 employs fully automatic 12V DC
to operate with a wide range of mains input
voltages and provides a stable output
voltage even under load. The unit can
provide up to 18 Amp maximum and 16 Amp
continuously.
SWITCH AND FUSES MODULE
Car/Van Selector Switch
The car/caravan changeover switch provided
in this module should be used in the
following way:
Caravan position -
When in this position DC power is
available from the caravan battery to
power all 12V electric circuits. If the
charger is switched on, the caravan
battery will be charged via the
charger/transformer unit. This position
should be used when operating the fridge
on 12V while towing.
Central position -
When in this position with the charger
switch on, power is provided to all 12V
circuits via the charger/transformer only.
With the charger off all DC circuits are
isolated.
Car position -
The switch can be placed in this position
should the caravan battery become
discharged and no mains power is
available.
Note: First of all the towing vehicle should
be electrically connected to the caravan via
the 12S socket.
ELECTRICAL AND THERMAL
PROTECTION
The battery charger is fitted with circuitry,
which will protect it in the event of electrical
or thermal overload. Should the current
draw exceed the rated output of the unit,
then it will begin to shut down. This will
probably be noticed as a dimming of the 12V
lighting. On removal of the excessive load
the charger will automatically recover. To
protect against overheating there is an
electronic thermal protection circuit, which
will operate should the temperature of the
unit rise above a safe level. If this happens
then the output will shut-off until the
temperature has dropped back to a safe
level.
CHARGER SWITCH
When the caravan battery requires charging,
press this switch to the on position (it should
then illuminate). Also ensure the Battery
Selector Switch is in the Van position.
SPACE HEATER AND WATER HEATER
SWITCHES
When you wish to use the space heater or
water heater press the relevant switch to the
on (downward position) It should then
illuminate to show the heater is powered
from the 230V supply.

For Bessacarr models an additional 12V fuse
box is located in close proximity to the
NC143 unit, with its own label appropriate to
function
