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 11VDC in and 13.6 VDC out, the output
current = 11/13.6 x 27 = 22.8 amps
