Victron 50A Autotransformer, 120/240 VAC

Description

The Victron 50A Autotransformer is designed for 120/240 VAC electrical systems that need voltage step-up, voltage step-down, or split-phase load balancing. It is particularly useful in marine, mobile, backup, and off-grid installations where the available AC source and the connected loads do not always use the same voltage arrangement.

In step-up or step-down applications, the autotransformer can be used to adapt between 120V and 240V AC requirements when the overall electrical design supports that configuration. Its split-phase balancing capability addresses another common problem: unequal loading between the two legs of a 120/240V system. By balancing current between the legs, the transformer can help a system use available inverter or shore-power capacity more effectively.

This model is rated for 50 amps and should be integrated with correctly sized conductors, overcurrent protection, grounding, and switching appropriate to the overall AC system. Because split-phase balancing involves interaction between both AC legs, installation should follow the system design and applicable marine or electrical standards rather than being treated as a simple plug-in accessory.

For vessels and off-grid systems that need flexible 120/240 VAC conversion or improved split-phase load balance, the Victron 50A Autotransformer provides a dedicated AC power-management component. More options in our shore power accessories.
