Marine Iso-Boost Transformer
The new Marine Iso-Boost transformer range from Energy Solutions provides a cost effective and reliable solution to isolate and manage a shore line, and the new size provides an exact fit and form replacement for the discontinued Charles Industries™ Iso-boost transformers. The units provide 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 Iso-Boost automatically switches back to 1:1 operation.
The units are available in Euro and USA specifications, with both 12kVA and 24kVA models. In the 24kVA size we also offer a European version that accepts 400 volts or 230 volts input. This allows owners to connect to three phase outlets – using two of the three phases.
