* A PWRgate is a simple 12VDC backup power
system that can supply up to 40 amperes continuously from either
a Power Supply or a Battery.
* A PWRgate is very useful in a Ham shack, at Repeaters, and
for Emergency Communications equipment centers.
* Connected equipment will instantly switch to battery during
AC Power blackouts or Power Supply failures.
* The PWRgate uses two 80 ampere Schottky diodes connected as
an OR-Gate to isolate the battery and power supply from each other.
* These Schottky diodes have a forward voltage drop of only 0.4
volt maximum thereby dissipating only 16 watts at 40 amperes and
to provide more than adequate power for most radios.
* The PWRgate has a built-in mini-charger circuit made up of
a resistor and diode that will provide up to 1 ampere to keep
the battery fully charged, ready-to-go and healthy.
* The built-in mini-charger circuit is optimized for sealed lead
acid GEL/AGM type batteries for a proper maintenance charge and
will keep a flooded lead acid marine or automotive battery near
full charge and healthy.

* 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 in December
2003 QST Page 41 titled "Emergency Power at W1ZR".
