Model 24S12.20QMW (ROHS) Input Range VDC Min 9 Max 36 Vout VDC 12 Iout ADC 20.5 Product is designed and manufactured in the USA. Converter operates at a fixed frequency and follows conservative component de-rating guidelines. The converters high efficiency and high power density are accomplished through use of high-efficiency synchronous rectification technology, advanced electronic circuit, packaging and thermal design thus resulting in a high reliability product. The 250 Watt QMW meets the most rigorous performance standards in an industry standard footprint for mobile (12Vin), process control (24Vin), military COTS (28Vin) and higher Vin applications. The output voltage is fully isolated from the input, allowing the output to be positive or negative polarity and with various ground connections. The 4:1 Input Voltage 250 Watt Single QMW DC/DC converter provides a precisely regulated dc output. High power density 4:1 Input voltage range Small size x 0.50" Efficiency to 92% Excellent thermal performance Auto-softstart Constant frequency Remote ON/OFF No minimum load requirement Good shock and vibration damping RoHS Compliant
