International Power Sources, Inc. NEW • UNIVERSAL INPUT • POWER FACTOR CORRECTION 350 WATT SWITCHING POWER SUPPLY DESCRIPTION The IFC350 Series is comprised of single and multiple output models capable of delivering 350 watts of continuous output power. All models have universal input and a power factor of better than 0.95. Auxiliary outputs use magnetic amplifier regulators to maintain tight output tolerances. U-bracket construction provides mechanical support and heat sinking. An optional cover-and-fan assembly is available. All models to meet CISPR22 and FCC Class B emission limits, and comply are approved UL, CSA, and TUV safety standards and carry the CE mark. FEATURES • EN61000-3-2, 3 compliant • Universal Input • Built-in EMI filter • Overvoltage and thermal protection • Short circuit protection with auto-recovery • Power fail detection (PFD) signal • 100% burn-in at full rated load • Optional cover-and-fan assembly OUTPUT VOLTAGE/CURRENT RATINGS CHART 3 4 Output #1 Output #2 Output #3 Output #4 Maximum Output 1 Model Vnom Imin Imax Tol.
