The HF100W-SF is a family of compact enclosed 100W AC/DC power supplies. These single output units offer high output power, compact packaging, high performance features, EN60950 approval, and CE certification at a very low cost (under $25 at OEM qty's). Seven models operate from a switch selectable AC input with ranges of 85 to 132 VAC or 170 to 264 VAC; offering single 100W outputs of 5VDC, 7.5VDC, 12VDC, 13.8VDC, 15VDC, 24VDC and 48 VDC. Standard features include tight line/load regulation of less than 0.5%, an input/output isolation of 3,000 VDC, leakage current of less than 0.7 mA, 20 mSec hold-up time, and high efficiency. Each unit is fully protected against output overload, over voltage or short circuit and the output is adjustable by ±10%. The MTBF (per MIL HDBK 217F) of the HF100W-SF series is greater than 100,000 hours. All models are approved to EN60950 safety standards and meet EN55022 B, EN55024, EN61000-3 and EN61000-4 EMC standards. The HF100W-SF family is packaged in a compact, aluminum enclosure and all connections are made by screw terminals. All models are specified for operation over the wide operating temperature range of -10°C to +50°C with no derating or heat sinking required. Cooling is by free-air convection. The HF100W-SF series is an ideal solution for a wide variety of AC power applications requiring small size, high performance and low component cost. Applications would include industrial/process control equipment, data acquisition equipment, test & measurement instrumentation and telecommunications systems. The HF100W-SF series is part of a full range of AC/DC products available from MicroPower Direct. These products are designed to provide long, reliable field life. Considerable attention is given to the proper selection, derating, and layout of all circuit components. In addition, extensive reliability screening is also performed on all products as a routine part of our production process.
