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.
- Vibration proof output voltage adjustment by 3 position DIP switch

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.

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
