As a step-up transformer it doubles a 120V supply to a 120\/240V split-phase output, and as a step-down transformer it takes 240V down to 120V, giving marine and off-grid systems the flexibility to adapt to whatever shore or generator configuration they meet. This 100A model shares the same transformer winding as the 32A version but allows far more current to pass straight through, suiting larger installations.\u003c\/p\u003e\u003cp\u003eIts most valuable role is balancing an unbalanced split-phase (120\/0\/120) supply. When 120V loads are spread unevenly across the two legs, one leg can reach its limit while the other still has spare capacity, so the supply is never fully used. Wired to create a new neutral, the autotransformer absorbs the imbalance through its windings so both 120V legs of the source share the load, unlocking the full power of a generator or two stacked inverters. It can also balance the output of a single 240V inverter feeding a split-phase system.\u003c\/p\u003e\u003cp\u003eA ground relay is built into the enclosure for use with a Victron MultiPlus or Quattro, creating the neutral-to-earth bond that a GFCI needs when the inverter\/charger runs in inverter mode. The unit is over-temperature protected: if it overheats the internal circuit breaker trips and is reset manually. Rated to 100A pass-through current in a toroidal design, it does not provide galvanic isolation.\u003c\/p\u003e","brand":"Victron","offers":[{"title":"Default Title","offer_id":56272729014612,"sku":"ITR000100101","price":589.2,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/9702\/3060\/files\/victron-15553417576788.jpg?v=1782995882","url":"https:\/\/hme.sprechen.dev\/products\/victron-auto-transformer-120-240v-input-output-100a","provider":"Hudson Marine Electronics","version":"1.0","type":"link"}
