Overview

The APS1250 1250W PowerVerter APS 12V DC 120V AC 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.

The DC-to-AC inverter features an automatic line-to-battery transfer switch and integrated charging system that allow it to work as a vehicle inverter, standalone AC power source or extended-run UPS. It delivers 1250W of continuous power, 1875W up to one hour, or 2500W 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, over-the-road trucks, fleet vehicles and emergency vehicles, the APS1250 converts stored power from any 12V battery or automotive DC source to safe, stable, computer-grade AC power and sends it to two NEMA 5-15R outlets for unlimited runtime. When powered by an external 120V AC source, the unit keeps the user-supplied battery charged via a three-stage 30A charging system while simultaneously delivering AC power to connected equipment.

When used as a UPS, the APS1250 responds to blackouts and brownouts with an automatic, instantaneous transfer to battery-derived AC output. LEDs on the unit indicate load level, battery charge level, shutdown status and system fault status.

Frequently Asked Questions

APS series inverters can accept and pass AC input power. They also have a built in battery charger circuit.
The APS1250 is made in China.
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.
