Simple and time saving installation
Bow thrusters of 160 and 220 kgf are only available in 24 Volt D.C. By installing the series/parallel switch (12 Volt batteries connected in series), the required 24 Volt can be obtained. For charging the 12 Volt batteries are automatically connected in parallel and linked to the 12 Volt charging system. This series/parallel switch comes with a pre-assembled auxiliary relays to ensure easy connection between the battery bank and the bow thruster. The charging contacts of the series/parallel switch have a continuous duty rating of 100 Amps and an intermittent rating of 150 Amps at 20% duty. The series/parallel switches meet the EMC requirements.

Note:
Thruster model BOW28548D is supplied as standard with a series/parallel switch to permit connection to a 24 Volt battery bank. This 24 - 48 Volt series/parallel switch can also be ordered separately: Code BP3008.
