Tripp Lite APS inverter/chargers include several features that ensure better equipment availability than competitors’ models. A high-amp, 3-stage charger allows users to safely recharge connected batteries at a faster rate than competitors’ models. This feature is critical in areas with inadequate utility service. Users in these areas know they only have a short window of opportunity when the lights are on to run equipment and recharge their battery systems. They do not want to waste their time with slower chargers that only charge their battery systems halfway, limiting the runtime of their connected equipment. With Tripp Lite’s APS Inverter/chargers, users have the confidence that they can quickly replenish their battery system’s power after a prolonged blackout while protecting against over-charge and over-discharge. If a power failure occurs, all APS inverter/charger models ensure continuous availability by quickly switching to battery backup support. Select APS models switch as fast as one half cycle (10 ms) - much faster than typical competitors’ models - making them ideal for supporting even the most sensitive computer and telecom equipment. If users experience a prolonged power failure which depletes the backup power of their battery system, select APS inverter/charger models will automatically switch on a gas generator to ensure continuous availability.
