Notes:
1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC. MIL-HDBK-217F Notice2 @Ta=25ºC, 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. Operating ambient temperature: Converter can meet the railway T2 and TX temperature requirement.
T2: -40ºC ~ +70ºC as all models , TX: -40ºC ~ +85ºC as power derating to 55% output power.(with Heat-sink as power derating to 70% output power)
Test condition with vertical direction by natural convection (20LFM).
8. Heat-sink is optional and P/N: 7G-0020C-F
9. EN55022 and EN55011
24VDC & 48VDC input: To meet Class B without external filter.
110VDC input: To meet Class A without external filter.
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: 24VDC & 48VDC input: Nippon chemi-con KY series, 220μF/100V, ESR 48mW.
110VDC input: Rubycon BXF series, 100μF/250V.
CAUTION: This power module is not internally fused. An input line fuse must always be used.
