MIL-HDBK-217F @Tc=70 ºC, Full load. 2. The converter is provided by basic insulation. 3. Typical value at nominal input voltage and no load. 4. Single：Typical value at nominal input voltage and full load. Dual：Typical value at nominal input voltage and both outputs current are 7.5A. 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 M/C(for dual outputs) or 1µF M/C and a 10µF T/C(for single outputs) 7. The negative / positive logic and pin length are optional. The pin voltage is referred to –Vin. Single：Please see single output product options table. Dual：Please see dual output product options table. 8. Heat-sink is optional and P/N: 7G-0021A-F, 7G-0022A-F, 7G-0023A-F, 7G-0024A-F. 9. The HEC75 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.
