BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC. MIL-HDBK-217F Notice2 @Ta=25 ºC, Full load (Ground, Benign, controlled environment). 2. The converter is provided by basic insulation. 3. Typical value at nominal input voltage and no load. 4. Typical value at nominal input voltage and full load. 5. Maximum output deviation is 10% inclusive of remote sense. If remote sense is not being used, the + SENSE should be connected to its corresponding +OUTPUT and likewise the –SENSE should be connected to its corresponding –OUTPUT. 6. Measured with a 1µF M/C and a 10µF T/C. 7. The negative/ positive logic and pin length are optional (see table). The pin voltage is referenced to –INPUT 8. Heat-sink is optional and P/N: 7G-0021A-F, 7G-0022A-F, 7G-0023A-F, 7G-0024A-F. 9. The HEC50 series standard module meets EN55022 Class A and Class B with external components. For more detail information, please contact with P-DUKE. 10. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The filter capacitor Power Mate suggest: Nippon chemi-con KY series, 220µF/100V. 11. CASE GROUNDING：When connect the case pin and four screw bolts to shield plane, the EMI could be reduced. CAUTION: This power module is not internally fused. An input line fuse must always be used. Page 2 of 3 www.pduke.com 2013/5/3 HEC50 SERIES 50 WATTS MECHANICAL DRAWING DC-DC CONVERTER ： 1.
