Victron Energy Isolation Transformers: User Manual & Safety Guide (EN)

www.victronenergy.com Isolation Transformers 2500 W, 4500 W, 800 0 W Safety and prevention of galvanic corrosion The Isolation T ransformer eliminates any electrical continuity between AC shore power and the boat. It is essential for safety and eliminates the need for galvanic isolators and polarity alarms. Safety Interrupter) will trip in case of a short circuit or current leakage to ground. Connecting the ground wire of the shore is taken for granted in case of a normal on - shore installation. A circuit breaker o r a GFCI (Ground Fault Current - side supply to the metal parts of the boat will result in galvanic corrosion (see below).

Bringing only t wire on board results in a n unsafe situation because GFCI s will not work nor will a fuse blow in case of a short circuit to he live and neutral a metal part on the bo at. Galvanic corrosion electrically conducting fluid. Seawater and, to a lesser extent, fresh water are such fluids. In general, the more active occurs when two dissimilar metals in electrical contact are simultaneously exposed to an alloy of the couple corrodes preferentially of galvanic corrosion is a function of several variables including area ratios, conductivity of the fluid, temperature, while the less active (more noble) material is cathodically protected. The rate nature of the materials, etc.

Isolation Transformer It is a misunderstanding boat as soon as a metallic part (the shaft and propeller) is in contact with water. Galvanic corrosion will quickly dissolve that galvanic corrosion occurs only in metal and aluminium hulls. In fact it can occur on any 45 00W your sacrificial anodes, and attack t connected to the shore - side supply. he shaft, propeller and other metal parts in contact with water as soon as the boat is It might therefore be tempting not to connect the ground conductor: this is however e GFCI s will not work nor will a fuse blow in case of a short circuit to a metal part on the boat. xtremely dangerous because The best solution Isolation T side supply.

ransformer to connect to the shore to avoid galvanic corrosion and at the same time prevent any uns - afe situation is to install an The Isolation T ransformer eliminates any electrical continuity between shore power and the boat. The shore power is fed to the primary side of the transformer and the ship is connected to the secondary. The I solation T ransformer completely isolates the boat from the shore ground. By connecting all metal parts to the neutral output on the secondary side of the transformer, a GFCI will trip or a fuse will blow in case of a short circuit. Soft start blowing due to the inrush current of the transformer, which would otherwise occur.

is a standard feature of a Victron Energy isolation transformer. It will prevent the shore power fuse from It is also recommended , for optimal safety, to connect the secondary neutral of the transformer to ground when the boat is out of the water. Isolation Transformer 800 0W 45 This 00 Watt Auto 115/230 model will automatically switch to 115 V or 230 V supply, depending on input voltage. V Supply 88 V Supply 185 250 V: switches to 230 130 V: switches to 115 V V supply supply range. Note : The AC input voltage is raised by 1:1.05 ratio at the AC output .
