Features

  • RV1250ULHW serves as an automotive or stationary DC-to-AC inverter with automatic line-to-battery transfer and integrated battery charger
  • Supports 120V AC output from a 120V AC line power source or 12V DC battery source
  • 16.6 millisecond automatic transfer between line and battery power supports UPS protection during blackouts and voltage fluctuations for equipment compatible with a one cycle transfer time
  • 1250 watts continuous AC output in inverter mode, 2400 watts continuous AC output in AC mode
  • Double Boost inverter output supports momentary startup loads up to 200% of the continuous rating for up to 10 seconds
  • OverPower inverter output supports longer duration overloads to 150% for 1-60 minutes under ideal battery and temperature conditions. (For best results, utilize OverPower usage for as short of a duration as possible, ensure battery bank and cabling is able to provide full nominal DC voltage under load and allow inverter/charger to fully cool before and after OverPower usage.)
  • 3 stage, selectable 14/55 amp battery charger with adjustable settings for wet/gel battery types offers fast, reliable battery recharging
  • Protected hardwire bolt-down input lugs safely accept heavy gauge input wiring from attached battery bank
  • Protected hardwire output passes 120V line power or inverter output through to connected equipment
  • Reliability enhanced large-transformer design tested to UL (USA) and CSA (Canada) standards
  • Moisture-resistant construction enables vehicular or marine operation in high humidity environments
  • 3 position operating mode switch supports "AUTO" mode to enable automatic transfer between DC and AC modes, CHARGE-ONLY to maintain a full battery charge when AC is present without auto transfer and SYSTEM OFF settings
  • Set of six front panel LEDs display AC/DC operational modes, overload status, DC voltage level, shutdown status and system fault status
  • Set of 4 configuration dipswitches 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
  • Set of 4 additional configuration dipswitches support 4 levels of charger limiting relative to output load size, a battery equalization program and battery charger low/high settings
  • Resettable 12A charger AC input breaker and resettable 20A AC output breaker and automatic 2 speed cooling fan protect the inverter from load and temperature related failures
  • Grounding lug properly connects the inverter/charger system to earth ground or vehicle grounding system
  • Automatic overload and thermal shutoff safely turns off inverter as excessive loads or overheating conditions develop
  • Front panel remote control connector enables remote off/on switching (requires APSRM4 switch accessory). Optional APSRM4 accessory also includes user configurable jacks to support inverter shutoff or startup as a vehicle ignition is engaged
  • Front panel remote control connector enables remote off/on switching (requires APSRM4 switch accessory). Optional APSRM4 accessory also includes user configurable jacks to support inverter shutoff or startup as a vehicle ignition is engaged
