Galvanic Isolator VDI-16 A
A galvanic isolator prevents electrolytic corrosion by blocking low voltage DC currents entering a boat via the shore power earth wire.
- The galvanic isolator prevents electrolytic corrosion.
- It consists of two diodes connected in anti-parallel fashion.
- Diodes allow current in both directions above a certain threshold voltage (about 1.4 Vdc).
- If there is a higher error voltage in the AC circuit, the diodes will allow current through and the residual-current device will break the circuit.
