The APS1250 efficiently converts DC power from a vehicle battery into 120V AC power for any type of equipment, from heavy-duty drills, saws and pumps to computers and sensitive monitoring equipment. The APS1250 provides safe, stable, AC output power to help connected equipment perform at its peak. A frequency control feature ensures that devices dependent on tightly regulated AC line frequency, such as computers, VCRs and DVD/CD players, receive clean computer-grade power.
Many tools, appliances and printers require extra power for start-up. Others, such as refrigerators and pumps, have fluctuating power demands. When operating in inverter mode, the APS1250 accommodates these peak surge demands by providing up to 200% more output power than its continuous rating of 1250 watts. In OverPower mode, the APS1250 can deliver 1875 watts for up to an hour, providing ample reserve power to keep tools and equipment running longer. In DoubleBoost mode, it can deliver 2500 watts for up to 10 seconds to support power-hungry equipment start-ups and motor cycling requirements. When connected to an AC power source, the APS1250 can provide up to 1440 watts continuous power.
When the APS1250 is connected to an AC power source, power is passed through to connected equipment and the battery set is charged via a three-stage, 20-amp charging system with adjustable settings for wet/gel battery types. In the event of a power failure or severe voltage fluctuation, the APS1250 responds with a near-instantaneous (16.6 millisecond) automatic transfer to battery power. Any number of user-supplied batteries may be connected to the APS1250 to provide extended battery backup support for critical equipment. A three-position switch enables you to select AUTO mode for automatic transfer between utility and battery power, CHARGE-ONLY mode to maintain a full battery charge with no automatic transfer switching when the APS1250 is connected to AC power or SYSTEM OFF mode.
