| Notes & safety | |
| Notes: | 1. MTBF: BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40°C. MIL-STD-217F Notice2 @ Ta=25°C, Full Load (Ground, Benign, controlled environment). 2. The output requires a minimum loading on the output to maintain specified regulations. Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications. 3. For single output models: maximum output deviation is 10% inclusive of remote sense and trim. If remote sense is not being used the +SENSE should be connected to the +OUTPUT and the -SENSE should be connected to the -OUTPUT. 4. Load regulation for dual output: Minimum load to 100% load balanced on all outputs. 5. Cross regulation for dual output: asymmetrical load 25% / 100% full load. 6. The ON/OFF control function: There are positive (standard) and negative logic (option). The pin voltage is referenced to negative input. To order negative logic ON/OFF control add the suffix "R" to the part number (Ex: DBW48S5-40R). 7. Heat sink is optional. Please call factory for ordering details. 8. The DBW series can meet EN55022 Class A with an external capacitor in parallel with the input pins. Recommended: For 24Vin: N/A. For 48Vin: 2.2uF/100V * 2 PCS 1812 MLCC. 9. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The filter capacitor suggested is Nippon chemi-con KY series, 220uF/100V, ESR 48MΩ. 10. This product is Listed to applicable standards and requirements by UL. Due to advances in technology, specifications are subject to change without notice. |
