All parameters NOT specially mentioned are measured at 12,24,48VDC input, rated load and 25 of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com) File Name:SD-50-SPEC 2011-08-23 50W Single Output DC-DC Converter Mechanical Specification 152.5 SD-50 Case No. 901 series Unit:mm 1 9.5 2 3 4 65 3.5 84.5 7 8.2 5 2-M 3 3.5 4.5 24 78 159 6.5 150 97 18.5 Terminal Pin No. Assignment Pin No. 1 2 3 Assignment DC INPUT V+ DC INPUT VFG Pin No. 4 5 Assignment DC OUTPUT -V DC OUTPUT +V 3.5 28.5 38 9 M3 22 117 Block Diagram fosc : 83KHz I/P EMI FILTER RECTIFIERS & FILTER POWER SWITCHING RECTIFIERS & FILTER +V -V FG O.L.P.
