MIL-HDBK-217F (25 ) OTHERS DIMENSION 99*97*36mm (L*W*H) 0.41Kg; 45pcs/19.5Kg/0.9CUFT PACKING 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature. NOTE 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. Line regulation is measured from low line to high line at rated load. 5. Load regulation is measured from 0% to 100% rated load. 6. 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:RT-50-SPEC 2011-08-19 3.5 50W Triple Output Switching Power Supply RT-50 series Mechanical Specification Case No. 905B Unit:mm 1 2 3 4 5.5 5 6 7 8 20.5 55 4.5 89 99 6.5 87 Terminal Pin No. Assignment Pin No. Assignment Pin No. Assignment 1 AC/L 5 DC OUTPUT V3 2 AC/N 6 DC OUTPUT +V2 74 18 3 7 DC OUTPUT COM FG 4 NC 8 DC OUTPUT +V1 RECTIFIERS Block Diagram fosc : 60KHz V3 & FILTER RECTIFIERS & +V2 FILTER RECTIFIERS RECTIFIERS EMI POWER +V1 I/P & & FILTER SWITCHING COM FILTER FILTER DETECTION FG CIRCUIT O.L.P.
