PRODUCT FEATURES
All versions of the IsoBoost have the following features:
•
A fully isolating hand built transformer
•
A soft start system to minimise the risk of tripping the shore side breaker when first connecting.
•
A sophisticated control system that will automatically select between boost and straight through mode on
US versions.
•
A sophisticated control system that will automatically select between buck and straight through mode on EU
versions.
•
Modbus data for optional remote monitoring the IsoBoost
Three versions are currently available
•
12 kVA US - A hull isolation transformer rated for a 50A 208/240V shore cord
•
24 kVA US - A hull isolation transformer rated for a 100A 208/240 shore cord
•
24 kVA EU - A hull isolation transformer rated for a 100A 230 shore cord or 63 amp 400 volt cord
The IsoBoost is packaged in a robust steel enclosure, powder coated for longevity. Care should be taken to lift the unit on a
pallet or by lifting from points on the transformer frame.
The IsoBoost is designed to operate automatically with no user intervention.
On the US model the IsoBoost starts in 1:1 mode. If the output voltage is below 215 volts the unit will switch to boost mode.
If the output voltage rises above 255 volts the unit will drop back to 1:1 mode.
On the EU model the control system will start the IsoBoost in 1:1 mode if the incoming voltage is between 190 and 255 volts.
The control system will start the IsoBoost in buck mode if the incoming voltage is between 340 and 440 volts.
All versions of the IsoBoost include a sophisticated multifunction meter built into the front of the case. It provides
comprehensive monitoring of the output from the IsoBoost, including voltage, current, frequency, power and more.
All versions are fitted with a cooling fan. Air is drawn in through the front of the unit below the meter, and expelled out the
rear right hand side. Do not block any cooling vents. If the fan fails, it must be replaced.
A thermal overload switch is incorporated within the transformer windings. If the transformer overheats, this will operate
and switch off the supply. Once it cools, it will reconnect. If this ever happens, check the cooling fan and seek advice. The
unit is designed and tested to work at full load in 60°C/140°F ambient conditions.
