TrippLite APS2448UL

Tripp Lite's APS2448 3-function DC-to-AC inverter with auto line-to-battery transfer and integrated charging system serves as a standalone 48V inverter or an extended run UPS.

This unit supplies up to 2400 watts of continuous 120V AC power from a 48V DC bus or battery set.
When optional-use hardwire input AC cable is energized, commercial power passes through to connected equipment and the battery set is recharged via 3 stage, 30 amp charging system.
In UPS mode, the APS system responds to blackouts and brownouts with an uninterrupted transfer to battery-derived AC output.

Includes:

Set of high current DC input terminals for simple installation (user supplies DC source and cabling).
Reliable large transformer design with efficient PWM sine wave output and frequency control powers resistive electronic loads or large inductive motors, compressors and other items with high current needs on startup.
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.
