Description
The battery separators (MBR) are micro-
processor controlled, powerful, mechanical
contactors. A MBR can be used in a
system consisting of two batteries (a start
and an auxiliary battery), like for instance
in boats or in camping-cars.
Possibilities
Connection according to the start
battery voltage
(See Connection p. 2)
In some 12/24 V installations (like in a
vehicle), it is preferable that the auxiliary
battery or the appliances are powered
only if the start battery voltage is
sufficient. By connecting a MBR between
the start battery and the auxiliary battery
or the appliances, the latter will only be
powered once the start battery voltage
has reached 13.2/26.4 V during 60
seconds.
Connection of a charger to the
auxiliary battery
(See Connection p. 2)
In a boat or in a camping-car it is usual to
connect a battery charger to the auxiliary
battery. By using a MBR, the start battery
will also be charged if the voltage of the
second battery is higher than 13.2/26.4 V
during
5
seconds.
In
case
your
boat/vehicle would stay without running
for a long time, your start battery will then
remain 100% charged. From the stop of
the charger, the contactor will open as
soon as it detects a voltage threshold
below 12.8/25.6 V during 60 seconds.
Contact for start assistance
(See Connection p. 2)
By connecting the terminal STATUS to the
positive (+) pole of the auxiliary battery
via the start contactor, the MBR will
commute the second battery at the start
of your boat/camping-car.
Security in case of overvoltage
(See Connection p. 2)
In case of a fault of the alternator voltage
regulator, the system voltage can easily
overcome the voltage limits allowed for
the
auxiliary
battery
and/or
the
appliances. This is why, in case of an
overvoltage, the MBR will detect the fault
and will disconnect the auxiliary battery
and/or the appliances in order to protect
them.
