Energy Solutions has released a new range of marine Iso Boost transformers voltage conversion models for boats being built for US markets as well as boats worldwide that may suffer from voltage drops from shorepower hook ups.

The 15kVA model offers the facility to select between two input tappings with 208V and 240V nominals, making them suitable for boats heading to the US. The 25kVA model is a unit with tappings at 400V and 230V allowing 230V boats to make use of 400V three phase supplies.

“The 15kVA Iso-Boost transformer is designed to give mid-range boats the ability to take advantage of two of these different shore supply offerings so that you have a greater chance of getting the power you need on board," said Paul Holland, Energy Solutions MD.

“When connected to a 240V supply the transformer uses a one to one tapping to give you 240V onboard. If the transformer detects that you have connected to a lower voltage - for instance by connecting to two phases or a 208 three-phase supply - it will select a different ‘boost’ tapping that will take the 208V input and increase it to 240V for onboard use.”

This transformer is offered at 15kVA to suit 50amp and 63amp shore-power inlet set-ups. This boosting arrangement is also useful for boats outside the US where low marina voltages are experienced, Paul added.

More power

The 25kVA model has been developed because while 'most European marina 230V single phase supplies max out at 63amps which means you are limited to bring 15kVA on board, if you can connect to two phases of a 400V three-phase supply the higher voltage means that you can bring more power on-board'.

Like the 15kVA model, the transformer automatically selects the correct tapping when the user powers up the boat.

The models are a great alternative to the Charles Industries Marine Iso-Boost which are no longer in production, said Paul.
