Description

120/240 VAC Autotransformer

The T240 is a great way to operate 240 VAC power tools and water pumps from a single inverter. 120 VAC is supplied to the T240 which steps it up to 240 VAC. This versatile autotransformer can also turn 240 VAC into 120 VAC. This allows the full output of a 240 VAC generator to be used by our 120 VAC battery chargers.

Applications

Step up: Allows you to power 240 VAC loads from a single 120 VAC inverter/charger. This is typically done for powering deep well pumps or other dedicated high power 240 VAC loads.
Step down: Allows you to connect a large 120 VAC load to the output of a stacked pair of DR or SW inverters (120/ 240 VAC). This results in the inverters sharing the load, allowing higher performance and efficiency.
Balancing Transformer: Allows a single 120 VAC inverter to be connected to a generator which has 240 VAC output. Keeps the generator balanced for better performance and operating life. Balancing the generator’s output also allows higher charge rates from your battery charger.

Note: This T240 replaces the old Trace model T220

The X-240 can be used as a 120 to 240 VAC step-up transformer, as a 240 to 120 VAC step-down transformer, as a generator balancing autoformer, or as a series stacked inverter-to-load balancing autoformer.

The X-240 can serve as a load balancing autoformer because, as one leg of the generator or one inverter in a stacked pair becomes fully loaded, it’s voltage drops slightly and current from the slightly higher voltage leg of the generator or inverter is automatically transferred through the autoformer to balance the load.

The X-240 can transfer up to 2kW (3kW with the optional X-240 fan kit) from one side of a split phase configuration to the other side regardless of the total power rating of the generator or the total power rating of a series/parallel FX inverter configuration.
