Achieve Optimal Power Distribution with the Victron Autotransformer

Achieve optimal performance and balance in your electrical system with the Victron Autotransformer. Designed for step-up, step-down, and split phase output balancing, this versatile device ensures efficient power distribution while safeguarding your equipment. Say goodbye to load imbalance issues and unlock the full potential of your power supply.

Effortless Step-Up, Step-Down, and Split Phase Balancing

The Victron Autotransformer simplifies the process of adjusting voltage levels and achieving split phase output balance. Whether you need to step up or step down the voltage, or balance the output of a split phase supply, this autotransformer has got you covered. Enjoy seamless integration with various power sources such as the grid, generators, or stacked inverters.

Eliminate Load Imbalance Challenges

In split phase systems, load imbalance can lead to uneven current distribution between the two legs, compromising the efficiency and capacity of your power supply. The Victron Autotransformer intelligently absorbs load imbalance, neutralizing the discrepancy in current flow. This ensures that each leg receives its fair share of power, enabling you to maximize the utilization of your electrical system.

Enhanced Safety with Built-in Ground Relay

Safety is paramount in any electrical setup, especially when using inverters and chargers. The Victron Autotransformer includes a ground relay specifically designed for use with MultiPlus or Quattro Inverter/Chargers. This relay enables proper functioning of Ground Fault Circuit Interrupters (GFCIs) and ensures that the neutral output is correctly grounded, providing you with peace of mind and a secure electrical environment.

Temperature Protection for Long-Term Reliability

Overheating can be detrimental to electrical components and lead to system failure. The Victron Autotransformer incorporates temperature protection mechanisms, automatically disconnecting from the power supply in case of overheating. This safeguard prevents damage and ensures the longevity of the autotransformer. Resetting the device is a simple and manual process, allowing you to quickly restore operation once the temperature has returned to a safe level.

A Superior Alternative to Stacked Inverters

For those seeking a split phase supply, the Victron Autotransformer offers an excellent alternative to stacked inverters. By combining a 240V inverter with an additional autotransformer, you can achieve a balanced 120/240V output with greater flexibility and power management. The Victron Autotransformer allows for load variations between the two legs, enabling you to make the most of your electrical system’s capacity.
