Description

Tripp Lite's APS2448UL 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. Supplies 2400 watts of continuous 120V AC power from any 48V DC bus or battery source.

Floating 48VDC ground offers compatibility with positive or negative grounded DC systems, including 48V telco applications. 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 the continuous output for up to 10 seconds, providing the extra power needed to cold start heavy-duty tools and motorized equipment.

When hardwire AC input is energized, commercial power passes through to connected equipment and the battery set is recharged via 3 stage, 15

amp 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. Includes a set of high current DC input terminals for simple installation (user supplies batteries and cabling - see owner's

manual for recommendations). Passes sine wave utilty 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 items with high current needs on startup. Optional APSRM4 wired remote power switch with

full status LEDs provides remote power inverter on/off switching and continuous status information (APSRM4 sold separate). Supports an unlimited

amount of runtime with any number of user-supplied batteries connected. Highly adaptable to a variety of applications and site conditions with

adjustable charger settings for wet/gel battery types and selectable line to battery power transfer voltages.

Applications

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

vehicles; a standalone alternative power source for off-grid, alternative energy or 48V networking applications and as an uninterruptible

power supply (UPS) for items compatible with an 8 millisecond transfer time.

Switches

3 position on/off/remote switch enables simple on/off power control plus "auto/remote" setting that enables distant on/off

control of the inverter system when used in conjunction with optional APSRM4 accessory when used in inverter mode. In

AC uninterruptible power mode, "auto/remote" setting enables automatic transfer from line power to battery power - to

maintain continuous AC power to connected loads.
