Overview

The APS2448UL 2400W PowerVerter APS 48VDC 120V Inverter/Charger is a reliable power source for a wide variety of equipment ranging from power tools and pumps to portable lighting and computer equipment in heavy-load conditions. With no fumes, fuel or excess noise, it’s an excellent alternative to generator power. And it’s tested to meet UL (U.S.) and CSA (Canada) safety standards.

The DC-to-AC inverter features an automatic line-to-battery transfer switch and integrated charging system that allow it to work as an extended-run UPS, standalone AC power source or vehicle inverter. It delivers 2400W of continuous power, 3600W up to one hour, or 4800W of peak power up to 10 seconds during equipment startup or cycling. An automatic overload detector, cooling fan and resettable AC circuit breakers protect the unit from damage.

Designed for easy installation in RVs, commercial and fleet vehicles, emergency vehicles and construction equipment, the APS2448UL converts stored power from any 48V battery or automotive DC source to safe, stable, computer-grade AC power for unlimited runtime.

When hardwired to an external 120V AC source, the unit keeps the user-supplied battery charged via a three-stage 15A charging system while simultaneously delivering AC power to connected equipment. When used as a UPS, the APS2448UL responds to blackouts and brownouts with an automatic, instantaneous transfer to battery-derived AC output.

Frequently Asked Questions

APS series inverters can accept and pass AC input power. They also have a built in battery charger circuit.
The APS2012 will run off generator power as long as the output of the generator meets the input requirements for that unit. That requirement is a nominal 120vac at 60hz.
Yes, we offer Pure Sine Wave Inverters. Visit our Inverters product category and filter for Pure Sine Wave Output. A pure sine wave inverter produces a smooth, sinusoidal AC output with a low level of distortion for better performance. A PWM (Pulse Width Modulated) Wave inverter produces a multi-step AC output that approximates a sinusoidal AC output with a higher level of distortion.
Thank you for your inquiry. The APSX1250 does support 3 stage charging with equalization.
APS-series inverters include a built-in battery charger. See our Inverter Buying Guide on tripplite.com for additional information and help with selection.
