Autotransformer 120/240V

Step-up and step-down autotransformer for creating split-phase 120/240V power or converting between voltage levels in North American systems.

The Victron Autotransformer converts between 120V and 240V, enabling split-phase output from single-phase inverters or stepping voltage up and down as required by the load configuration. Available in 32A and 100A models, it handles loads from small appliance circuits to full-panel distributions. Greater than 97% efficiency means minimal power loss and heat generation, even at continuous rated load.

VE.Bus communication allows integration with MultiPlus and Quattro systems for coordinated power management through a GX device. The autotransformer supports both 50Hz and 60Hz operation, making it adaptable to international deployments. Its robust construction is designed for permanent installation in power distribution panels and equipment cabinets where reliable voltage conversion is critical.

Used in Alchemy industrial power systems for split-phase 120/240V distribution in off-grid installations, voltage step-up for 240V equipment on single-phase inverter systems, and mobile power platforms serving mixed-voltage loads.
