Notes:
1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC. MIL-HDBK-217F Notice2 @Ta=25 ºC, Full load (Ground, Benign, controlled environment)
2. Typical value at nominal input and no load.
3. Typical value at nominal input and full load.
4. Test by minimum input and constant resistive load.
5. Trimming allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting an external resistor between the TRIM pin and either the
+OUTPUT pin or the -OUTPUT pin.
6. The CTRL pin voltage is reference to -INPUT. The order number please see product standard table.
7. Test condition with vertical direction by natural convection (20LFM).
8. Heat-sink is optional and P/N:7G-0047C-F
9. EN55022
1) To meet Class A without external components.
2) To meet Class B please refer to the suggestion filter in next page.
10.An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5.
The filter capacitor Powerbox suggest: Nippon chemi-con KY series, 220μF/100V, ESR 48mW.
CAUTION: This power module is not internally fused. An input line fuse must always be used.
