Outback Power Systems VFX Series Ventilated Inverter VFX3048E 3.0 kWAC 48 VDC Vented Construction Features: Powdercoated all aluminum die-cast chassis Internal electronic components are cooled by outside air Stainless steel screen to protect air intake and internal fan UL 94V0 plastic vent grills to protect the air exhaust. All openings are 0.0025 inches square to keep out dirt, bugs, and other critters – we call it “bug proof” construction Air inlet comes with removable, washable foam filter insert to trap small particles Conformal coated circuit boards to resist corrosion Higher output power when inverting or battery charging when compared with the sealed FX inverter versions Designed to allow easy field servicing and repair Ideal Applications: Montana or Arizona etc. where salt air is not a problem and climate is dry More watts per dollar Installations where well protected environments are available   DCC cover included! The new OutBack VFX series is a ventilated version of our original sealed FX series modular "building block” sine wave inverter/charger that can be used for both small and large power systems. By allowing cooler outside airflow through the internal electronics, more AC power is available and operation in extremely hot environments is improved compared to the sealed FX series. Each OutBack FX or VFX inverter/charger is a complete power conversion system - DC to AC inverter, battery charger and AC transfer switch. Additional FX inverter/chargers can be connected at any time in either parallel (120 VAC), series (120/240 VAC), or three-phase (120Y208 VAC) configurations. This allows a system to be tailored to meet the specific power conversion requirements of the application, both at the time of the installation and in the future. The OutBack VFX series is also available in export versions (E)with 230 VAC, 50 hz output that can be connected in parallel (230 VAC) or in three phase (230Y400 VAC) configurations. Like the FX series, the OutBack VFX is also designed to survive harsh environments around the world. The full sreened vent openings are "bug-proof" and the die-cast aluminum chassis protects and keeps the power conversion components cool in very hot environments even when operated at high power for extended periods. The VFX can be used in high ambient applications up to 60oC (with reduced output ratings). The OutBack VFX series inverter/charger system is designed for both residential and commercial stand-alone or back-up power applications with battery energy storage. It is designed to operate as a coordinated system with the other OutBack products i.e. the PSDC, PSAC and PSR enclosures as well as the MX60 MPPT charge controllers and MATE system controller and display.     Specifications VFX2612E* VFX 2812 VFX 3024E* VFX 3048E* VFX 3524 VFX 3648 Continuous Power Rating at 25 degrees C 2600VA 2800VA 3000VA 3000VA 3500VA 3600VA Nominal DC Input Voltage 12 12 24 48 24 48 Nominal AC Input Voltage / Frequency 230V/50Hz 120V/60Hz 230V/50Hz 230V/50Hz 120V/60Hz 120V/60Hz Continuous AC RMS Output current at 25 C 11.3 amps 23.3 amps 13 amps 13 amps 29.2 amps 30 amps Idle Power (typical at no AC load) (sleep – 3 watts) 18-20 Watts 19-21 Watts 18-20 Watts 21-23 Watts 18-20 Watts 21-23 Watts Efficiency (typical at 25 degree C and 75% resistive load) 89% >90% >90% >90% >90% >90% Total Harmonic distortion voltage (typical / max) 2% / 5% 2% / 5% 2% / 5% 2% / 5% 2% / 5% 2% / 5% Output Voltage Regulation +/- 2% typ +/- 2% typ +/- 2% typ +/- 2% typ +/- 2% typ +/- 2% typ Surge Power Capability Peak (1mSec) 35 amps AC 70 amps AC 35 amps AC 35 amps AC 70 amps AC 70 amps AC Surge Power Capability RMS (100mSec) 20 amps AC 50 amps AC 25 amps AC 25 amps AC 50 amps AC 50 amps AC Overload Capability (from 25 C start) 5second 4000 VA 4800VA 4800 VA 4800 VA 5000VA 5000VA Overload Capability (from 25 C start) 30 minutes 3100 VA 3200VA 3300 VA 3300 VA 4000VA 4000VA Automatic AC transfer Relay (at nominal AC) 30 amps AC 60 amps AC 30 amps AC 30 amps AC 60 amps AC 60 amps AC AC Input Current (adjustable limits) 30 amps AC 60 amps max 30 amps max 30 amps max 60 amps max 60 amps max AC Input Voltage Range (adjustable limits) 200-260 VAC 90-140VAC 200-260 VAC 200-260 VAC 90-140VAC 90-140VAC Frequency Range – AC Input 40 to 60 Hz 54-67.4 Hz 40 to 60 Hz 40 to 60 Hz 54-67.4 Hz 54-67.4 Hz DC Input Range (adjustable low battery cut-out) 10 – 16.5 VDC 10-16 VDC 20-33 VDC 40-66 VDC 20-33 VDC 40-66 VDC Recommended DC Breaker OBDC-250 OBDC-250 OBDC-250 OBDC-175 OBDC-250 OBDC-175 Continuous Battery Charger Output amps DC 125 amps 125 85 amps 45 amps 85 45 Shipping Weight 62 Lbs 62 Lbs 62 Lbs 62 Lbs 62 Lbs 62 Lbs
