DC Voltage Autotransformer 12 to 24 or 24 to 12 Volts DC 20 Amps

This rugged and versatile unit is used to power a small load at 12 V from a 24 V battery, or to power a small 24 V load from a 12 V battery. It functions both ways, producing 12 V @ 20 Amps from a 24 V input or can be connected backwards to produce 24 V @ 10 Amps from a 12 V input.

When connected as a battery equalizer, it allows large transient 12 V loads to be taken off the centre tap of a 24 V battery (made of 2 X 12 V batteries) without fear of upsetting the voltage balance of the battery and destroying the 24 V battery system that would otherwise occur.

We accept all major credit cards, PayPal and eCheck (via PayPal). We ship to all states and Canadian provinces, and to about 40 other countries.
