Product Spotlight - Super Powergate 40S Backup Power Switching and Charging System

The perfect complement to a 400 watt inverter, this unit is ideal for the ham shack, Home Office computer system, or off grid cabin or RV.

Description:

* A Super PWRgate is a 12 volt backup power system that can supply up to 40 amperes continuously from either a Power Supply or a Battery, and can also charge the battery with its high performance charger.
* Connected equipment will instantly switch to battery during a power blackout or power supply failure. No glitches.
* The circuit uses two 80 ampere Schottky diodes as an OR-Gate to isolate the battery and power supply from each other. Forward voltage drop of less than 0.3 volts at 20 A.
* To keep the battery fully charged and ready for use, the Super PWRgate has a built-in four-stage battery charger with selectable current rates of 1, 4, 7 or 10 amperes.
* The circuit is optimized for use with GELLED & AGM type batteries, but will keep flooded lead acid and marine type batteries near full charge as well.
* The Super PWRgate and the power supply may also be used to charge a battery that is powering the radio, as described by W1ZR in QST.
