A PWRgate is a simple standby backup power system, it will allow communications equipment to remain operative on battery power during AC power blackouts. Power supplies and batteries can be swapped out while the equipment remains on with no glitches.
What is the Low Loss PWRgate?
The Low Loss PWRgate uses MOSFET power transistors to switch the load between power sources with less than a 20 miliVolt drop, much smaller then similar systems that use Schottky diodes. This keeps the power losses to a minimum and delivers full battery power to the load.
The Low Loss PWRgate transfers up to 25 amperes at up to 16 volts dc continuously. It is a safe way to connect both a 12 volt battery and a 13.8 volt power supply to a load, while electrically isolating both from each other. Whenever your power supply is on, the supply feeds the load while also charging the battery, keeping the battery healthy and ready for use when the power supply is off or looses AC power. Switching is instantaneous.
What type of battery should I use?
The Low Loss PWRgate has been designed to use Sealed Lead Acid batteries such as AGM (Absorbed Glass Mat) or GelCell batteries from 7 Amp Hour to 70 Amp Hour capacity.
Yes, there is a built in Float Charger that will keep your battery fully charged and ready.
