Victron Energy Autotransformer 100A 120/240V Split Phase Transformer Step Up Step Down Balancer ITR000100101

Victron Energy Autotransformer 120/240V Split Phase 100A

The Victron Energy Autotransformer 120/240V Split Phase 100A is a professional-grade power management solution designed for split-phase balancing, voltage conversion, and inverter system integration. It provides efficient step-up, step-down, and neutral balancing capabilities for residential, marine, off-grid, RV, and commercial power systems.

Designed to maximize the available power from 120/240V split-phase sources, the Victron Autotransformer helps eliminate load imbalance between the two 120V legs. By creating a new neutral connection, it allows uneven 120V loads to be balanced while improving the usable capacity of generators, grid connections, and stacked inverter systems.

Advanced Split Phase Load Balancing

In typical 120/240V split-phase systems, uneven 120V loads can cause one leg to reach its maximum current limit before the available power capacity is fully utilized. The Victron Autotransformer absorbs this imbalance through its windings, allowing the system to operate more efficiently and make better use of available power.

Multiple Power Conversion Applications

The Autotransformer can be used for several applications, including:

• Split phase output balancing for 120/240V systems
• Step-up voltage conversion
• Step-down voltage conversion
• Integration with Victron Multi and Quattro inverter/chargers
• Alternative solution to stacked 120V inverters

Built-In Safety Features

The Victron Autotransformer includes a temperature protection system that disconnects the unit during overheating conditions. Manual reset functionality provides additional safety and protection for demanding installations.

Ground Relay for Victron Inverter Systems

An integrated grounding relay allows proper neutral-to-ground bonding when used with compatible Victron Multi or Quattro inverter/chargers. This helps ensure correct operation of GFCI protection and safe inverter-mode operation.
