Victron Energy Autotransformer 120/240V-100A

The Victron Energy 120/240V 100A Autotransformer is designed to step voltage up or down and balance uneven loads in split-phase electrical systems. In RVs, marine installations, and off-grid power systems, it helps redistribute unbalanced 120V loads between the two legs of a 120/240V supply, making better use of the available power. It features a toroidal transformer, built-in circuit breaker, temperature protection, and a grounding relay for compatible Victron inverter/chargers.

FEATURES

• Voltage conversion: Supports step-up, step-down, and 120/240V split-phase load balancing.

• 100A pass-through capacity: Allows up to 100A of current to pass through without being converted.

• Load balancing: Transfers power between split-phase legs to help manage uneven 120V loads.

• Toroidal transformer: Designed for efficient power transfer.

• Built-in protection: Two-pole circuit breaker provides overcurrent and temperature protection.

• Grounding relay: Supports neutral-to-ground bonding with compatible Victron MultiPlus or Quattro inverter/chargers when correctly connected.

• Durable enclosure: Aluminium housing with IP21 protection.

• Applications: RVs, marine systems, off-grid installations, and backup power systems.
