DC/DC Auto-Transformers as switching converters

DC/DC Auto Transformers are designed to decrease the DC voltage fed into the unit. Theses isolated, enclosed DC-DC converters are designed to increase, or decrease, the DC voltage fed to the unit.  Functioning as solid state converters they have a high efficiency and provide regulated 13.8 VDC output from an input of 20 -30 VDC.  We use them to power 12-volt lights or appliances using a 24-volt system. For example the 12 / 24 V model will produce 12 V from 24 V AND can be connected backwards to produce 24 V from a 12 V source. Handy for driving a 24 V pump from a 12 V power source.
