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.

Product Specifications

Electrical Specifications

  • Input/Output Voltage: 120 / 240V
  • Frequency: 50/60Hz
  • Input Circuit Breaker: 32A, two pole
  • Maximum 240V Feed-Through Current: 32A
  • Neutral Current (30 min): 32A (3800 VA)
  • Neutral Current (Continuous): 28A @ 40ºC / 100ºF
  • Transformer Type: Toroidal

Key Features

  • Split Phase Balancing: Absorbs load unbalance by creating a new neutral, allowing one leg to supply higher current while maintaining a balanced draw from the primary 240V source.
  • Integrated Ground Relay: Specifically for use with MultiPlus or Quattro inverter/chargers. When in inverter mode, it ensures the neutral output is connected to ground for proper GFCI operation.
  • Temperature Protection: In the event of overheating, the Autotransformer automatically disconnects from the supply. Resetting the device is a manual process for added safety.
  • Stacked Inverter Alternative: Offers a robust alternative to stacking two 120V inverters by using a single 240V inverter paired with the Autotransformer to manage unbalanced 120V loads more efficiently.
