SeaBis Automatic Isolator & Distribution.
For vessels where changing the engine or cabin equipment for marine 2 wire isolated is not practical.
Marine isolated equipment, starter motors, alternators, winches have battery negative and positive large diameter wires to the battery. Their (metal) body is isolated from both battery wires. Marine electrically isolated equipments all have connections isolated from their metal body so are isolated from all wet metal so do not cause electrolysis. This isolation is only present with commercial equipment.
Unfortunately recreational equipment is often not isolated. However recreational equipment is turned off 99% of the time. The Automatic Isolator disconnects the power when that equipment is OFF. It is connected in series with the battery to the cabin / engine. It is Closed, via the SeaBis Special Devices supplied with the Isolator, during cabin power ON or engine ON. When they are OFF the Automatic Isolator is Open Circuit so preventing them from causing electrolysis.
The Automatic Isolator is continuously rated at 200 amps RMS (RMS - heating effect - RMS the safest and only absolute method of measurement) 2200 amps peak and the solenoid has silver contacts. Continuously rated explanation: If you start your engine twice in 30 seconds that is continuous rated. SeaBis special devices prevent other equipments from causing electrolysis and are supplied with the Isolator.
The enclosure is tough polycarbonate. All wall through bolts are O ring sealed and are stainless steel.
Distribution:
Distribution is used to supply battery to the remainder of the vessel / engine. If the remainder of the vessel has a part such as Diesel PreHeaters or Gas Ignition that is not isolated from the body, and replacement with marine isolated parts is not practical, then they can be from the Isolator.If the alternator is causing electrolysis and the alternator can not be changed for marine two wire isolated then it can be powered from the Isolator.
Full details are supplied with the Automatic Isolator.
If your engine hours exceed 200 per year then the option of Full Isolation should be considered. This option involves changing all single wire parts to marine 2 wire isolated.
Fit the SeaBis System - its the most economic way for you to protect your vessel.
