Single Output DC Converter,
Enclosed, Screw Terminal Connectors,
Input: 72~144vdc
Output: 11-15 vdc,
NOTE: This converter is designed for a 120volt    
              DC battery pack. (144 when charged)  
If you have a higher voltage pack, you will        
        need the converter sold below
We  have two series of DC converters available -
The SD line is for battery pack voltages between 72 and 144 vdc.

The SP line is for battery pack voltages between 124 and 370 vdc.
                                         
Several different outputs are available between 150 and 1000 watts (11-74 Amps)
                          @ 13.5 volts DC
             Prices from 99.00 and up

   Typical Loads

Please calculate your expected
maximum constant amp draw
and size your DCDC accordingly
We cannot be responsible for
problems from using an
undersize converter.
Remember, volts x amps =
watts.  For example, a headlight
draw of 8 amps at 13.5 volts =
108 watts,  which is a good
percentage of a smaller dcdc's
output.  We also recommend
using a battery in the 12 volt
system even when using a
converter.
