Isotransformer 2000 – 120 240 V 50 60 Hz
Description
Whisperpower isolation transformers offer optimal safety by eliminating shock hazards to life beings on board and in the water adjacent to a boat, by preventing AC current flow from the shore to metal objects on a boat, thereby stopping nuisance tripping of RCD (residual current device) or GFCI (ground fault circuit interrupt) systems when on shore power.
- Safety by galvanic isolation of AC power
- Prevention of galvanic corrosion
- Includes circuit breaker on primary
- Low noise, low weight toroidal transformer with vibration isolated mounting
- Global shore power 230 V or 120 V input, 50 or 60 Hz
- Configurable for 230 V, 120 V or Split Phase 120+120 V ship supply output
Our isolation transformers also reduce possible galvanic corrosion of hulls, propellers, or other metal parts under a ship, eliminating the need for installing galvanic isolators, sacrificial anodes and polarity alarms. By preventing DC currents traveling between a shore ground connection and metal parts of a ship, no current flow path between two dissimilar metals (electrically in contact and simultaneously exposed to an electrically conductive liquid) can occur, and corrosion is thus prevented.
It is important, therefore, that the Ground conductor from the Shore connection is NOT CONNECTED to the Power Inlet housing nor the Isolation Transformer enclosure PE (except temporarily when in dry-dock). On the floating AC output of the Isotransformer, it is possible to jumper a Neutral-Ground bond for allowing GCFI/RCD breakers onboard.
Warning: Never disconnect the shore Ground (PE) conductor unless you use an Isotransformer. Because GCFI/ RCD will not trip, nor a fuse will blow in the case of a short circuit current to metal parts on a vehicle, always use an Isotransformer with Neutral-Ground bond on the secondary.
