Description
The Victron Energy 120/240V 50A Autotransformer is designed to provide flexible voltage conversion and load balancing in AC electrical systems commonly used in marine, recreational vehicle and off-grid power installations. It allows systems designed for 120V or split-phase 120/240V operation to operate safely and efficiently when connected to different power sources.
One of the key applications of the autotransformer is step-up and step-down voltage conversion, enabling users to convert 120V to 240V or 240V to 120V depending on system requirements. This makes it particularly useful when integrating shore power with onboard electrical systems.
The autotransformer can also be used for load balancing between the two legs of a split-phase 120/240V supply, helping to optimise the use of available shore power. By balancing loads across both phases, it allows higher total power consumption without overloading a single phase.
When combined with Victron inverter/chargers such as the MultiPlus or Quattro, the autotransformer can further improve system flexibility by ensuring compatible voltage supply for different appliances.
Designed for demanding installations, the unit supports continuous currents up to 50A and includes built-in temperature protection for safe operation. The robust construction and compact design make it suitable for professional electrical installations in vehicles, boats and energy systems.
