Victron Autotransformer 120/240VAC-50A - ITR000100052

Victron Autotransformer 120/240VAC-50A - ITR000100052

The Victron 120/240V-50A autotransformer is basically a device that serves to adapt the electricity when the voltage you have does not match the voltage your equipment needs.

It does not generate electricity or charge batteries, it simply acts as a translator between different voltages.

It is very common in installations where 120 volts and 240 volts are used, typically on ships, solar systems, generators and hybrid installations or installations imported from other countries.

If you've ever found that “the current doesn't fit” with what you need to connect, this device is designed to do just that because it is a reliable, stable and safe solution.

Characteristics of the Autotransformer 120/240VAC-50A

Main function

Its main function is to convert 120 V to 240 V or to correctly split a 240 V system into two balanced 120 V lines.
This makes it possible to power equipment operating at different voltages without the need to change inverters, generators or electrical appliances.

It also plays a very important role in installations with 240 V output divided into two 120 V phases (split-phase), the autotransformer helps to balance the loads between these phases so that no circuit is overloaded.
This improves system stability and reduces the risk of electrical failure.

In addition, in systems where the grid or generator varies in voltage configuration, this device gives you the flexibility to adapt the output to what your appliances really need without having to duplicate inverters or use more complex solutions.

Voltage and current

It is rated up to 50 amps, which allows it to handle considerable power, sufficient for large residential installations, boats, small workshops or medium-sized solar systems.
It is not a small plug-in device, but something designed to work seriously and continuously.

It is compatible with both 50 Hz and 60 Hz frequencies, allowing it to operate without problems in different countries, with different generators or with variable power grids.

Design

This autotransformer has a solid and robust metal housing and is designed for indoor installation.

It has an IP21 degree of protection, suitable for dry environments such as electrical rooms, switch cabinets or technical compartments on ships.

Inside it uses a toroidal transformer, which is more efficient, compact and quiet.
This means that it has less energy losses, heats up less and is more stable in operation over time.

As a passive device, it generates no interference, introduces no appreciable electrical noise and requires little maintenance once installed.

Safety and security

The Victron autotransformer has its own protections, including a circuit breaker, which protects the system against overloads or abnormal situations.

This adds extra safety for both the equipment itself and the rest of the electrical installation.

Connections and ease of installation

The connections are made via robust screw terminals, which are designed for large cable cross-sections, ensuring a secure, firm and long-lasting connection even at high currents.

The design is intended to facilitate a tidy and professional installation, compatible with standard electrical panels.

Compatibility

This autotransformer is compatible with Victron Energy systems and equipment from other manufacturers.
It is especially useful when working with inverters that only deliver 120 V but need to power 240 V equipment, or when a split-phase system needs to be balanced correctly.

On boats and campers it is particularly useful, as it can be hooked up to different types of power supply depending on the port, country or available generator, without having to modify the existing installation.
