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. |
