Step up a 12 VDC battery to between 13.5 and 17.0 or 24.0 and 27.5
VDC in 0.5 VDC increments (via 3 position DIP switch), or stabilize a 12
or 24 VDC power system.
Safety features include reverse input protection, low input voltage
alarm, low output voltage alarm, over temperature shutdown and alarm,
a dry contact alarm relay output and output overvoltage crowbar. If the
input voltage exceeds the regulated output voltage, the unit simply
passes the voltage through with full LC filtering and a single schottky
diode drop (0.5 VDC or less). Optional features include remote panel
monitoring with On/Off control.
Applications include temporar i ly brightening 12 volt headlights or work
lights, increasing voltage into an automotive or marine ignition system
for hotter spark and/or prevention of failures due to voltage drop during
engine start, stabilizing 12V and 24 VDC power systems in marine,

♦ 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 Vo lts x 27
For example, at 11 VDC in and 13.6 VDC out, the output current = 11/13.6 x 27 = 22.8 amps
