Description

Tripp Lite UT1250UL Utility Work Truck Inverter / Charger are 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 1250 watts of continuous 120V AC power from any 12V DC battery or automotive DC
source. OverPower inverter output feature temporarily provides up to 150% of the continuous output for 1-60 minutes, and DoubleBoost inverter
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 10/40Amp charging system. In UPS mode, the UT 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, with frequency control, powers resistive electronic loads or large inductive motors, compressors and other devices with high current needs on
startup. 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 UT1250UL supports an unlimited amount of runtime with user-supplied batteries.

Applications

Versatile inverter / charger system with auto-transfer switching serves as an automotive inverter for utility work trucks, conversion vans and fleet

service vehicles; a standalone power source for off grid, alternative energy or export applications, emergency home power applications such as

sump pumps, and as an uninterruptible power supply (UPS) for items compatible with a 16.6 millisecond transfer time
