CHOOSING BETWEEN AN OUTBACK SEALED OR VENTED POWER INVERTER/CHARGER Sealed FX Power Inverter/Chargers The FX series is designed to survive in environments that would normally destroy other inverter/ chargers. Protection for internal components is provided by our die-cast aluminum chassis with a powder coated finish to prevent corrosion. Internal and external cooling fins allow for passive heat transfer, enabling peak operating efficiencies as high as 93% and looking cool while doing it. Water and small particles are kept out through the generous use of gaskets and 0-ring seals on all seams and openings. A protective conformal coating on all circuit boards provides the final line of defense against corrosion. The now standard externally mounted “TURBO” cooling system improves performance in hot conditions. ---------------------------------------------------------------------------------------- Vented VFX Power Inverter/Chargers The VFX series is designed for more protected installations. By utilizing an efficient active cooling design, the VFX models are available with AC output up to 3.6 kilowatts. Our tough die-cast aluminum chassis physically protects the internal components while the air intake includes an easily cleaned filter, which allows for ventilation while also keeping bugs and other debris out. All circuit boards are conformal coated to prevent corrosion from airborne moisture in humid conditions. The now standard DC wiring cover (DCC) protects the DC terminals and battery cables from damage. ----------------------------------------------------------------------------------------
