Technical Specifications User manual
The Victron Energy 120/240V 32A Autotransformer is designed to step voltage up or down and balance uneven loads in split-phase electrical systems. Ideal for RVs, marine installations, and off-grid power systems, it helps redistribute unbalanced 120V loads between the two legs of a 120/240V supply, allowing available power to be used more efficiently. It features a toroidal transformer, built-in circuit breaker, thermal protection, and a grounding relay for compatible Victron inverter/chargers.
FEATURES
Voltage conversion: Steps 120V AC up to 240V AC or 240V AC down to 120V AC.
Split-phase load balancing: Helps redistribute uneven 120V loads between both legs of a 120/240V system.
32A pass-through capacity: Supports up to 32A of 240V feed-through current.
Toroidal transformer: Designed for efficient power transfer.
Built-in protection: Two-pole circuit breaker and thermal protection; overheating disconnects the supply and requires a manual reset.
Grounding relay: Supports neutral-to-ground bonding with compatible MultiPlus or Quattro inverter/chargers when correctly configured.
Durable enclosure: Aluminium housing with IP21 protection.
Multiple applications: Suitable for RVs, marine electrical systems, generators, and off-grid installations.
