Rigblaster PG-40S Super PWRgate Back Up Power System 4 Stage 10 A Charger Circuit Built In

FEATURES:

• 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".
