Maximum output deviation is 10% inclusive of trim. 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. The positive logic and pin length are optional ( see table ). The CTRL pin voltage is referenced to -INPUT. 7. Heat-sink is optional and P/N：7G-0029A-F, 7G-0030A-F, 7G-0031A-F, 7G-0032A-F. 8. The QEB125 series standard module meets EN55022 Class A and Class B with external components. For more detail information, please contact with P-DUKE. 9. 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, 220 F/100V. 10. BASE-PLATE GROUNDING：When connect the four screw bolts to shield plane, the EMI could be reduced. 11. The converter is provided by basic insulation. μ CAUTION: This power module is not internally fused. An input line fuse must always be used.
