Manufacturer Contact Info

The Tripp Lite APS1250 is a 12V DC-to-120V AC inverter/charger with automatic transfer switching, suited to users who need backup power for compatible equipment during blackouts or voltage fluctuations. It delivers 1,250W continuous inverter output and transfers between line and battery power in 16.6 milliseconds.

Recommended For

RV, truck, and fleet-vehicle operators who have a 12V battery bank and need installed 120V AC power for tools, pumps, lighting, or appliances while away from shore power.
Construction, emergency-response, or remote-site crews who need a stationary or vehicle-mounted inverter/charger for equipment such as power tools, motors, pumps, and portable lighting.
Users building battery-backed power for compatible computer or networking equipment who want automatic transfer from 120V AC line power to a 12V battery during an outage and have checked that their equipment tolerates the transfer time.
Stationary or mobile battery-system owners who want one unit to provide 120V AC from a 12V battery and recharge that battery when AC power is available.

Real-World Use Scenarios

In an RV or service vehicle, a user can connect the APS1250 to a 12V battery bank to run compatible 120V appliances or electronics when shore power is unavailable; when AC power returns, it can pass that power through and recharge the batteries.
At a remote work site or in a fleet vehicle, a user can power compatible corded tools, tool chargers, or portable lights from a battery bank; actual runtime depends on the connected load and available battery capacity.
For a small off-grid or backup-power setup, a user can pair the APS1250 with a 12V battery bank to supply AC to compatible equipment; battery size and recharging arrangements determine how long it can run.
When connected between AC power and compatible equipment, the APS1250 can switch to battery power during an outage, helping keep loads such as selected computer or communications equipment running; users should confirm the equipment tolerates its transfer time and inverter output.
In an emergency or utility vehicle, a user can keep selected 120V equipment powered from the vehicle’s battery system while away from an outlet; high loads require suitable batteries, cabling, and installation.
