DC UPS & Power Control
The abrupt DC system voltage drop that accompanies engine starting can cause micro-processor based voice and data transmitters to “dump” programmed memory.
StartGuard solves this problem by providing supplemental voltage to sensitive electronics while the engine is cranked. It contains a sealed rechargeable battery which is switched on-line to electronics when sensing the starter switch or solenoid is engaged. When the engine is running, the StartGuard automatically goes off-line and the internal battery is recharged by the alternator.
NAV-PAC contains an internal 5 ah battery and noise suppression circuitry which provides a clean and stable source of DC power to vehicle transceivers, data terminals, fare boxes and navigation systems. Mobile electronics are highly vulnerable to shut down / reboot / data corruption caused by power drop out during engine start, and low voltage from over worked batteries. RF Interference generated by alternators and motors also impedes proper operation. Nav-Pac addresses all these power issues and has proven very effective in ensuring proper operation of electronics in public safety vehicles, commercial fleets, and buses.

Feed sensitive electronics with proper voltage regardless of battery condition. These stabilizing converters provide continuous, precisely regulated output over the entire range of a battery’s usable voltage. This prevents subjecting loads to fluctuating input voltage which can cause shutdown, diminish performance and possibly damage sensitive circuitry.
The interference or electronic “noise” generated by alternators, ignition systems, motors, etc., can render a vehicle’s radio, data receivers or other electronic equipment making them virtually useless. This interference takes the form of popping or static on radios or audio gear and garbled images or “hash” on video displays.
The Automatic Power Selector (APS) is a solid state device which enables installation of a seamless, redundant power system for critical electronic loads. It selects the higher voltage of two isolated DC power sources and routes power to the load. Should one source falter or fail, the other will automatically supply the load with no transfer delay, operation continues uninterrupted.
Eliminate dead vehicle batteries caused by power drain from radios and data terminals that must operate while the engine is off. Allows use of accessory loads per programmed time limit while preserving battery for engine start.
Charging multiple battery banks without use of diode isolators dictates that the batteries be connected or “integrated” only whenever a charge voltage is present so that they may be charged simultaneously, then disconnected or “isolated” when in use to allow for selective discharge and avoid having the secondary or standby battery drain into the primary battery.
Battery Integrators perform this function automatically, acting as a “smart” switch to connect independent battery banks only when a charging voltage is present. Otherwise, they are isolated, and discharge between banks is prevented.
Heavy duty isolators allow charging multiple batteries automatically from one or two alternators and prevent discharge from one battery bank to another. Each battery is charged according to need without overcharging. Rated for 12-48 volt negative ground systems
