The APSX1250 1250W APS X Series 12V DC 230V 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 its 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 conversion vans the APSX1250 converts stored power from any 12V battery or automotive DC source to safe stable computer-grade AC power and sends it to two C13 outlets for unlimited runtime. When powered by an external 230V AC source the unit keeps the user-supplied battery charged via a three-stage 7.5/30A selectable charging system while simultaneously delivering AC power to connected equipment. When used as a UPS the APSX1250 responds to blackouts and brownouts with an automatic instantaneous transfer to battery-derived AC output. LEDs on the unit indicate AC/DC operational modes overload status DC voltage level shutdown status and system fault status.Reliable Power for Mobile Emergency and Remote Sites Generates safe stable computer-grade 230V AC power from 12V battery bank Ideal for powering tools saws motors portable lighting small appliances and computer equipment in heavy-load conditions Designed for easy installation in RVs over-the-road trucks fleet vehicles and conversion vans Functions as a vehicle inverter standalone AC power source or extended-run UPS Features dual C13 outlets Unlimited runtime with variety of user-supplied batteriesMeets Normal and Peak Power Demands 1250W of continuous power 1875W of reserve power up to 1 hr. 2500W of peak power up to 10 sec. to accommodate surge power demands during equipment startup and cycling Automatic overload detector built-in cooling fan and resettable AC circuit breaker protect unit from damageAutomatic Transfer Switching Transfer relay switches to inverter power during blackout in 10 ms 3-position switch enables Auto Charge Only or System Off mode DIP switches configure high and low voltage auto-transfer3-Stage 7.5/30A Selectable Battery Charger Serves as battery charger when external 230V AC power is supplied and powering connected equipment Protects battery from overcharging and overdischarging Low-battery protection prevents excessive battery depletion DIP switches configure wet/gel charging profilesOptional Remote Control Capability RJ45 communication port allows connection of optional remote control module such as Tripp Lites APSRM4Front-Panel LEDs Indicate AC/DC operational modes overload status DC voltage level shutdown status and system fault statusRugged Polycarbonate Housing Resists moisture vibration and impact Built-in mounting feet for installation on any rigid horizontal surface Detachable 2 m C13-to-C14 power cord connects to AC power source Delivers clean 230V AC power from AC or DC power source 1250W continuous output power; 2500W peak power Auto-transfer switching option for UPS operation Protects against blackouts surges and EMI/RFI line noise Rugged polycarbonate housing resists moisture and impactPackage Includes APSX1250 1250W APS X Series 12V DC 230V AC Inverter/Charger Owners manual
