The EOS Power LFWLT450-1001 is a single-output AC/DC converter providing a regulated 12V output at 37.5A (250W convection, 450W forced air). It accepts a universal input of 90-264 VAC (120-390 VDC) with a frequency range of 47-63 Hz. Active power factor correction delivers a power factor of 0.98 typical at 120VAC and 0.95 at 230VAC. Efficiency reaches up to 86% at 120VAC for the 12V model (88% for 24/48/30V models at 120VAC, 90% at 230VAC). The converter includes comprehensive protection: over-current (120-150% hiccup), over-voltage (>114% latch), short-circuit autorecovery, and over-temperature (130°C primary heatsink, autorecovery). Hold-up time is 10ms at both 120VAC and 230VAC. The unit measures 165.1mm x 101.6mm x 41.0mm and weighs 900g. Features include adjustable output (±3%), remote on/off, remote sense, standby output, and current sharing for up to two units in parallel. Convection cooling provides 250W; forced air at 420 LFM increases output to 450W. Operating temperature range is 0°C to 70°C with derating; startup is guaranteed down to -20°C.
