The UT2012UL Utility Work Truck Inverter / Charger is the quiet alternative to gas generators with no fumes, fuel or noise. It provides equipment with utility or generator supplied AC electricity filtered through premium ISOBAR surge protection. This DC-to-AC inverter with automatic line to battery transfer and integrated charging system serves as an extended run UPS, a standalone power source or an automotive inverter suitable for rugged work site applications. Supplies up to 2000W of continuous 120V AC power from any 12V DC battery or automotive DC source. OverPower output feature temporarily provides up to 150% of the continuous output for 1-60 minutes, and DoubleBoost output feature delivers up to 200% of continuous output for up to 10 seconds, providing the extra power needed to start heavy-duty tools and motorized equipment. When AC cable is connected to a live wall socket, commercial power passes through to connected equipment and the battery set is recharged via 3 stage selectable 15/60Amp charging system. In UPS mode, the APS system responds to blackouts and voltage fluctuations with a near instantaneous automatic transfer to battery derived AC output. A set of high current DC input terminals is included for simple installation (user supplies batteries and cabling – see owners manual for recommendations). Passes sine wave utility or generator power during battery charging and UPS line power operation, plus efficient PWM sine wave AC output in inverter and UPS backup modes. Reliable large transformer design (tested to UL (USA) and (CSA) Canada standards) with frequency control, powers resistive electronic loads or large inductive motors, compressors and other devices with high current needs on start-up. Included is the APSRM4 wired remote power switch with full status LED’s, which provides remote power inverter on/off switching and continuous status information. The UT2012UL supports an unlimited amount of runtime with user-supplied batteries.
