Victron 100A 120/240V Split-Phase Autotransformer

Uneven loading between the two legs of a split-phase power system can limit usable shore or generator capacity. This Victron 100A autotransformer is intended for 120/240V arrangements that need step-up, step-down, or split-phase balancing. It can be used alongside suitable inverter and shore-power equipment.

In a split-phase system, 120V loads on one leg may differ substantially from loads on the other. The autotransformer helps manage the imbalance instead of requiring every appliance to draw the same current on each leg. Its 100A classification needs to be checked against the source, protection, and system wiring. Balancing is relevant when different appliances are connected to opposite 120V legs.

This is AC power-distribution equipment and requires installation suitable for the boat's electrical system. Confirm the intended voltage configuration before connecting it. The transformer does not remove the need for correctly sized breakers, conductors, or protective grounding. Browse more shore power accessories at CritPro.
