Autotransformers & Transformers
Available at Solar Taos 2010 Product Catalog
Toroid Autotransformers 

These AC step-up and step-down transformers are greater than 98% efficient and cause less than 0.2% idle loss at no load. They are nearly silent when operating. Use an autotransformer as a step-down to connect the 240 volt output of a generator to the 120 volt input on an inverter. This allows full output power of a 240 volt generator to be used for battery charging.

Autotransformers can step-up voltage to operate 240 volt appliances and motors from the 120 volt output of an inverter. NEMA3R enclosures with knockouts for conduit. 2-year warranty.

Solar Converters DC Autotransformers

These high-efficiency DC to DC converters can be used to step-up or step-down battery voltage.

These converters are bidirectional so they can be used to increase or decrease voltage.

They can be used to operate 12-volt loads on a 24- or 48-volt battery system or to run a 24-volt refrigerator on a 48-volt battery system.

See table for up and down voltage and current limits.

1-year warranty.
