The 160 kgf and 220 kgf bow thrusters are only available with a 24
Volt DC electric motor.
By installing a series/parallel switch in a 12 volt main power
supply system it is possible that:
The 24 Volt bow thruster will work using 12 Volt batteries
connected in series, therefore obtaining the required 24 Volt.
Also for charging, the 12 Volt batteries are automatically
connected in parallel and linked to the 12 Volt charging
system.
This series/parallel switch comes complete with pre-assembled
auxiliary relays to ensure easy connection between the battery bank
and the bow thruster.
When the installed batteries for the bow thruster are also used for
other 12 Volt consumers, it should be remembered that the current
is supplied via the charging contacts of the series/parallel
switch.
These contacts have a continuous duty rating of 100 Amps., and
an intermittent 20% rating of 150 Amps.
As a consequence, never use these batteries as starter batteries
and never connect an anchor windlass to them.
The series/parallel switch functions completely automatically and
therefore the operation of the bow thruster is as usual.
The 285 kgf – 48 Volt DC bow thruster has a series/ parallel
switch supplied as standard in order to permit connection to a 24
Volt battery bank.
This 48 Volt series/parallel switch is also available separately
(code: BP3008).
The series/parallel switches meet the EMC requirements.
