PFM™, AC-DC Converter with PFC Universal Input, 24 V or 48 V Regulated, Isolated Output For use in: Small Cell Base Station, Telecom Switching Equipment, LED Lighting, Test and Measurement Equipment, 200 - 400 W Industrial Power Systems and Office Equipment Value Proposition Today's AC-DC power systems need to be small, reliable, easily-to-use, and cost competitive while achieving modern system requirements for efficiency, power factor, and conducted and radiated emissions. Vicor has solved these difficult challenges by combining advanced power conversion engines and electromagnetic compatibility functions inside the thermally adept and ultra-low-profile VIA package. Board mount Features and Benefits n Small Size, low profile: Chassis mount Eliminates constraints of size or height in a design n Thermally adept VIA housing: Enables easy thermal design, possibly eliminating the need for a fan; chassis mount version enables system chassis to be part of thermal design Product Description n Integrated filtering, transient protection, inrush protection: Simplifies EMI and surge protection design, faster time to market n High efficiency of up to 92%: Excellent efficiency for such a small and low profile device n Active Power Factor Correction (PFC) exceeding 0.95 at most line/ load conditions (filter dependent): Meets all agency standards n 400 W available over entire input voltage range: No need to design different systems for different parts of the world n Chassis mount or PCB mount packaging options: Provides design flexibility, enables multiplicity of thermal design strategies n Small and simple “wall-plug-to-PoL design with Vicor PoL buck, and buck-boost regulator products: Simple, modular complete solution to achieve benchmark performance from wall-plug to Point of load The PFM is a highly advanced 400 W AC-DC converter operating from a rectified universal AC input which delivers an isolated and regulated Safety Extra Low Voltage (SELV) 24 V or 48 V secondary output. This unique, ultra-low profile module incorporates AC-DC conversion, integrated filtering and transient surge protection in chassis mount or PCB mount form factor. The PFM enables a versatile two sided thermal strategy which greatly simplifies thermal design challenges. When combined with downstream Vicor DC-DC conversion components and regulators, the PFM allows the Power Design Engineer to employ a simple, low-profile design which will differentiate his end-system without compromising on cost or performance metrics. n Easy-to-use solution requires only a few external components (rectifier, fuse, MOV, hold-up caps): Allows for design flexibility n 24 V version operates with ~27 mF of 35 V hold-up capacitors 48 V version operates with ~6.8 mF of 63 V hold-up capacitors (application dependent): Small, flexible design n Voltage, current, and temperature protections: Protects the PFM unit and system Part Numbering Product Function P F Package Package Length Width M PFM = Power Factor Module 4 9 Inches x 10 1 Package Type 4 Inches x 10 V B = Board VIA V = Chassis VIA Max Input Voltage B 6 B6 = 85–264 Vac Range Ratio M M = 3.1 Max Output Voltage (Range) 2 4 24 = 24 Vout 48 = 48 Vout Max Output Current/Power D 0 D0 = 400 W vicorpower.com Product Grade C C = -20 to 100°C T = -40 to 100°C Option Field 0 0 00 = Chassis Always-on 04 = Short Pin/Always-on 08 = Long Pin/Always-on Rev 1.4 9/2015 Typical Application, 24 VOUT PFMs 48 V Output AC 85 – 264 Bridge Rectifier PFM 24 V Output 24 V Cool-Power ZVS Buck LOAD 1 Cool-Power ZVS Buck Cool-Power ZVS Buck LOAD 2 LOAD 3 Cool-Power ZVS Buck Cool-Power ZVS Buck LOAD 4 LOAD 5 Mechanical Diagram (Chassis mount version shown) A B .152 3.861 THRU TYP 1 .11 2.90 3 1.171 29.750 1.40 35.54 4 2 USE TYCO LUG #696049-1 OR EQUIV.
