| Notes & safety | |
| Notes: | 1. BELLCORE TR-NWT-000332. Case 1: 80% Stress, Temperature at 40°C. MIL-HDBK-217F Notice2 @Ta=25°C, 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. Typical value at nominal input voltage 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 remote ON/OFF control pin voltage is referenced to –INPUT. To order negative logic Remote ON/OFF control add the suffix “R” to the model number (Ex: DCQEB50-48S05R). 7. Heatsink is optional and P/N: 7G-0029A-F, 7G-0030A-F, 7G-0031A-F, and 7G-0032A-F. 8. The DCQEB50 series meets EN55022 Class A and Class B only with external components added before the input pins to the converter. 9. An external input filter capacitor is required if the module has to meet EN61000-4-4 and EN61000-4-5. We recommend Nippon chemi-con KY series, 220µF/100V, ESR 48mΩ. 10. BASE-PLATE GROUNDING: EMI can be reduced when you connect the four screw bolts to the shield plane. 11. The converter is provided with basic insulation. 12. Safety Approvals: DCQEB50-48S1.8, 48S2.5, 48S3.3, and 48S05 have safety approvals; approvals pending for all other models. 13. This series comes with several different options: Negative remote ON/OFF control, pin lengths, thru-hole inserts, and heatsinks. CAUTION: The power module is not internally fused. An input line fuse must always be used. Due to advances in technology, specifications subject to change without notice. |
