Do you need a clean, quiet, reliable power source for automotive, remote site, industrial, commercial or residential applications? Tripp Lite's APS2448UL Inverter/Charger is the solution you seek! This DC-to-AC inverter/charger powers the equipment you commonly use at home or work—power tools, pumps, portable lighting, notebook computers and more. It's the ideal power solution for RVs, commercial and fleet vehicles, emergency vehicles, construction sites, remote worksites and any other application that requires a clean, quiet AC power source. The APS2448UL efficiently converts 48V DC (battery) power into 120V AC (household) power to run any type of equipment, from power tools to computers. Unlike portable generators, the APS2448UL requires no fuel and produces no noise or fumes. The APS2448UL also features automatic line-to-battery transfer and an integrated battery charging system for UPS (uninterruptible power supply) applications where an AC power source is present. In UPS mode, the APS2448UL powers connected equipment while keeping connected batteries fully charged. If AC power becomes unavailable, the APS2448UL automatically switches to battery power. The APS2448UL also features OverPower™ and DoubleBoost™ capability, providing extra power when required for heavy loads and power-hungry equipment start-ups.

UL-Certified Output Power

The APS2448UL efficiently converts 48V DC power from a vehicle battery into 120V AC power for any type of equipment, from heavy-duty drills, saws and pumps to computers and sensitive monitoring equipment. The APS2448UL provides safe, stable, AC output power to help connected equipment perform at its peak. A frequency control feature ensures that devices dependent on tightly regulated AC line frequency, such as computers, VCRs and DVD/CD players, receive clean computer-grade power. The APS2448UL also features a floating 48V DC ground that provides compatibility with positive or negative grounded DC systems, including 48V telecom applications. The APS2448UL is tested to UL (USA) and CSA (Canada) standards.

Extended Peak Surge Power

Many tools, appliances and printers require extra power for start-up. Others, such as refrigerators and pumps, have fluctuating power demands. When operating in inverter mode, the APS2448UL accommodates these peak surge demands by providing up to 200% more output power than its continuous rating of 2400 watts. In OverPower mode, the APS2448UL can deliver 3600 watts for up to an hour, providing ample reserve power to keep tools and equipment running longer. In DoubleBoost mode, it can deliver 4800 watts for up to 10 seconds to support power-hungry equipment start-ups and motor cycling requirements. When connected to an AC power source, the APS2448UL can provide up to 2400 watts continuous power.

Auto-Transfer Switching for UPS Operation

When the APS2448UL is connected to an AC power source, power is passed through to connected equipment and the battery set is charged via a three-stage, 15-amp charging system with adjustable settings for wet/gel battery types. In the event of a power failure or severe voltage fluctuation, the APS2448UL responds with a near-instantaneous (8 millisecond) automatic transfer to battery power. Any number of user-supplied batteries may be connected to the APS2448UL to provide extended battery backup support for critical equipment. A three-position switch enables you to select AUTO mode for automatic transfer between utility and battery power, CHARGE-ONLY mode to maintain a full battery charge with no automatic transfer switching when the APS2448UL is connected to AC power, or SYSTEM OFF mode.

Diagnostic LEDs

The APS2448UL features six front-panel diagnostic LEDs to indicate load level (high, medium and low), battery charge (high, medium and low), shutdown status and system fault status.

Overload Protection

To prevent damage to the inverter and connected equipment, the APS2448UL will shut down automatically if an overload is detected at the AC output connection. The red Load Level Indicator LED will flash to alert you that an overload has occurred. Additional overload protection is provided by a 25-amp AC input circuit breaker, a 20-amp AC output circuit breaker, and a built-in multi-speed cooling fan.

Heavy-Duty Construction

The APS2448UL features a rugged, moisture-resistant polycarbonate housing that withstands vibration, impact and high-humidity environments—ideal for use at remote worksites, in trucks, RVs and other vehicles, on boats or anywhere that reliable AC power is needed.

Simple Installation and Equipment Connection

The APS2448UL features integral mounting slots for permanent installation on any rigid, horizontal surface, such as the bed of a pickup truck. Connecting the APS2448UL to your battery system is quick and easy with readily available user-supplied cables. A grounding lug on the side of the unit connects the inverter/charger to earth ground or vehicle grounding system. AC input power and AC output power for connected equipment is provided via a hardwire junction box on the front of the unit. A load-sensing control dial enables the load threshold to be adjusted to automatically turn the inverter on and off in DC mode as load conditions change. Four configuration dip switches support wet/gel battery charging profiles, adjustable 135/145V high voltage auto transfer during overvoltages and selectable 75/85/95/105V AC low voltage auto transfer during brownouts. A second set of four configuration dip switches support four levels of charger limiting relative to output load size, a battery equalization program and battery charger low/high settings.

Optional Remote Control Capability

The APS2448UL is equipped with an RJ45 port for connection of an Remote Control LED/Switch Module (Tripp Lite model APSRM4), enabling you to control and monitor the inverter/charger from virtually anywhere within a vehicle.

Peace of Mind

The APS2448UL comes with a 1-year product warranty and a rapid-response repair/replacement policy that's unmatched in the industry.

Also Available

Tripp Lite manufactures a full line of power and connectivity solutions—UPS systems, power distribution units, surge suppressors, cables and connectivity solutions, rack enclosures and more—for every application, from the desktop to the datacenter.
