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 temporarily 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 Volts x 45
For example, at 10.5 VDC in and 13.6 VDC out, the output current = 10.5/13.6 x 45 = 34.7 amps
Whichever is greater Whichever is greater
