| BTCPower S25 Series Description TM Broadband TelCom Power, Inc. Redefining "Current" Limits In Power Conversion 25W High Efficiency Low Power Bricks The S25 series of high efficiency, low power DC/DC converters offer power levels that exceed other bricks with similar footprint. With a wide input voltage range of 18-36 or 36-75V they are available with an output voltage of either 1.5, 1.8, 2.5, 3.3, or 5 Volts. All models feature an input filter, input undervoltage lockout, overtemperature protection, output current limiting and short circuit protection. The fully enclosed, encapsulated construction aluminum heat spreader design achieves very efficient heat transfer with no hot spots. The use of patented design concepts facilitate maximum power delivered with the highest efficiency up to 90%. The converters combine creative design concepts with highly derated power devices to achieve very high reliability, high performance and low cost solution to systems designers that are challenged to maximize power and minimize board space.
