Note :
1. MIL-HDBK-217F @Tc=70 ºC, Full load.
2. Typical value at nominal input and full load. (20MHZ BW)
3. Typical value at nominal input and no load.
4. Typical value at nominal input and full load.
5. 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 QEB75 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.
CAUTION:
This power module is not internally fused. An input line fuse must always be used.
