Trace T240 Autotransformer

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.
