Product Information
The Energy Solutions IsoBoost transformer provides a cost effective and reliable solution to isolate and manage a shore line. It provides all of the features of a normal isolation transformer, as well as providing a boost function to manage the volt drop on heavily loaded shore lines, or to cope with a 208V (phase to phase) supply.
On startup, the isolation transformer automatically soft starts the transformer to prevent inrush from tripping the supply breaker. If the voltage is in range, it operates in 1:1 mode, so that the output voltage matches the input voltage. If the supply voltage drops below 215V, it automatically switches into boost mode, effectively raising the output voltage by around 10%. If the supply voltage recovers, the IsoBoost automatically switches back to 1:1 operation.
The IsoBoost features:
• Double wound isolation transformer to BS EN 60076-1
• Custom enclosure, powder coated RAL9016 traffic white finish
• Input is automatically switchable between 208/400 (configured at time of order) and 240 volts nominal
• Protective screen between input and output windings (normally connected to incoming earth)
• Output is 240 volt nominal, with centre tap available#
• Dual frequency (but no frequency conversion)
• Input 3 wire (earth and two conductors)
• Output options for 3 wire or 4 wire
• Models available for US or EU operation (208V or 400V)
• Automatic soft start to prevent shore supply tripping
• Inbuilt metering, logging and power analysis
• Fit and form replacement for Charles Industries™ Isoboost transformers
A sophisticated power meter is built into the case of the IsoBoost. It provides detailed monitoring of the output supply of the transformer, allowing the user to check that the supply is acceptable before connecting it to the vessel switchboard. The power monitor is also used to provide the control of the boosting function. It includes the following:
• Voltage, frequency, current monitoring
• Power, power factor and energy usage
• Harmonic content and THD
• Event and alarm recording
• Modbus RTU communication for optional remote display
Boost function
The output voltage of the transformer is directly related to the input voltage. This output voltage, when the transformer is in Boost mode, is +10% higher than the input voltage on the European specification transformers and +15% higher than the input voltage on US specification transformers. The boost function will typically happen at the following voltage levels:
European Spec: Input Voltage is below 218V USA Spec: Input Voltage is below 220V

Manufactured In the UK
We design and manufacture a wide range of products in our factory in the UK. We have invested in state of the art cable processing machines to allow us to automate many aspects of our production, guaranteeing quality and consistency. Our engineering department use advanced mechanical and electrical design tools to drive this process, and we use computerised testing machines to speed up loom construction and validation. We also have in-house facilities to laser cut and engrave control panels, along with 3D printing for prototyping components. None of this manufacturing would be possible without a skilled team of staff, with years of experience in complex builds.
Partners
We work with leading international manufacturers and distribute their products in order to supply our customers with a complete electrical power, monitoring and control solution. We work with some of the biggest names in each market sector and have established ourselves as a key supplier bringing new ideas and technical updates on a continual basis.
