Autotransformer 120/240VAC-32A

The Victron Autotransformer 120 V/240 VAC−32 A is a multifunction device for power systems, providing voltage step up, step down, and essential load balancing for unbalanced 120 V/240 V split phase supplies.

Voltage Conversion: Handles step up (120 V to 240 V) and step down (240 V to 120 V). Load Balancing: Optimises power use in 120 V/240 V split phase systems with unbalanced loads. 32 A Rating: Features a maximum 240 V feed through current of 32 A. Built-in Ground Relay: Essential safety relay for neutral-to-earth bonding with Victron Inverter/Chargers. Safety Protected: Includes over current protection via a two-pole circuit breaker and thermal disconnect.

Product Details

Unleash the full potential of your 120 V/240 V power system with the Victron Autotransformer 120 V/240 VAC−32 A. This versatile component is engineered for three primary functions: step up, step down, and split phase output balancing, ensuring your power source is used efficiently in marine, RV, and off-grid setups.

In split phase systems supplied by generators, the grid, or stacked inverters, unbalanced 120 V loads often prevent the full power capacity from being utilised. The Autotransformer effectively "absorbs" the current unbalance between the two legs, allowing maximum power to be drawn without overloading one side. This makes the 32 A unit a superior alternative to stacking two 120 V inverters for a split phase supply.

For safety and seamless integration, it includes a ground relay which, when coupled with a Victron MultiPlus or Quattro Inverter/Charger, ensures the neutral output is correctly earthed in inverter mode for proper GFCI functioning. Built with a robust toroidal transformer and a durable aluminium enclosure, this 32 A Autotransformer provides reliable, temperature-protected power conversion.
