PERATING PRINCIPLE
The IT3600 range of CRISTEC isolation transformers function is to provide a galvanic isolation between the boat on-
board power supply network and the shore.
This separation prevents ground current circulation between the supply and distribution lines, which are the source
of corrosion on the metal parts of a vessel in contact with sea water (phenomenon similar to electrolysis).
This isolation function is made of a toroidal transformer with dual primary and secondary winding.

NRUSH CURRENT REDUCER
The system has an automatic soft-start function to limit inrush current when the device is switched on, avoiding
inadvertent tripping of shore network protections (premagnetising circuit).

2.3
HERMAL PROTECTION
The device has an automatic 2 speeds ventilation system (half speed below 45 °C in the casing, full speed above
45 °C). A safety thermal sensor protects the equipment in case of overheating (too high ambient temperature,
overloading etc,).
