* The actual output current capability depends upon the input/output voltage ratio.
   To obtain the actual output current capability at any given input voltage,
   use the following formula:
Output Amps = Input Volts/Output Volts x 27
For example, at 11 VDC in and 13.6 VDC out, the output current = 11/13.6 x 27 = 22.8 amps
