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, automotive or aeronautical environments and more.

Military Option

Most of the products manufactured by Analytic Systems can be adapted for military use (Commercial Off The Shelf).




We provide four different levels of ruggedization; most often, a product in military use will use the extra-wide temperature range components to allow operation from -40°C  to +55°C.




The printed circuit boards are also protected against condensation and are enhanced with vibration protection that meets or exceeds MIL-STD810F, Method 514-3 and Cat-1 Proc 1.




C.O.T.S. products are designed to meet various levels of EMC radiated and conducted emissions MIL-STD 461F.




All C.O.T.S. products are manufactured in accordance with IPC-A-610.




Applications: Military, Electric Utilities, Substations, Base Station Power, Industrial Controls and OEM.

* 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
