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.

These DC-DC converters are designed to decrease the DC
voltage that is inputted into the unit. These switching converters
have a high efficiency and provide regulated 13.8 VDC output
from and input of 20 -30 VDC. Use them to power 12-volt lights
and appliances from a 24-volt system.
