ISO+ GALVANIC ISOLATORS
CRISTEC offers two ranges :
– European range that includes models with 16A and 32A capacities.
– North American range which is specifically designed for the North American market and holds 32A & 64A ABYC A28
and Fail Safe certifications.
The galvanic isolator prevents galvanic corrosion. It blocks the low-voltage DC currents that enter your boat via the shore power earth wire. These currents can cause corrosion to the boat’s underwater metals, like the hull, propeller, shaft and so on.
The galvanic isolator consists of two diodes connected in antiparallel. The galvanic isolator is connected between the shore earth connection and the central earth point in the boat.
The advantage of the galvanic isolator is its low weight and size. In contrast to a galvanic isolation transformer that ensures full isolation (live, neutral, and ground), a galvanic isolator does not prevent corrosion that may arise through the neutral line, particularly when the neutral line is grounded by onboard electrical components, including suppression filters or other devices.
