Note
1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at Tc=40ºC. MIL-HDBK-217F Notice2 @Ta=25 ºC, Full load(Ground, Benign, controlled environment). 2. Maximum value at nominal input voltage and full load. 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. Dual output safety approvals pending. 8. The negative / positive logic and pin length are optional. The pin voltage is referenced to -Vin. Single:Please see single output product options table. Dual:Please see dual output product options table. 9. Heat sink is optional and P/N: 7G-0021A-F, 7G-0022A-F, 7G-0023A-F, 7G-0024A-F. 10. The HEC75 meets EN55022 class A and class B only with external components connected with the input pins of the converter. 11. 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, ESR 48mΩ. 12. BASEPLATE GROUNDING:Base-plate should be grounded at one of the four screw bolts prior to operation. 13. The converter is provided by basic insulation.
