Note
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. Maximum value at nominal input and full load.
3. Typical value at nominal input and no load.
4. Typical value at nominal input and full load.
5. Test by minimum input and constant resistive load.
6. 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.
7. The ON/OFF pin voltage is reference to -INPUT.
The order number please see product standard table.
8. Heat-sink is optional and P/N:7G-0047C-F
9. The LCD15 series can meet EN55022 Class A with parallel external capacitors to the input pins.
Recommend: 12 VDC input: 10μF /25V 1812 MLCC
24VDC input: 2pcs of 6.8μF /50V 1812 MLCC
48VDC input: 2pcs of 2.2μF /100V 1812 MLCC
10. 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.
CAUTION:
This power module is not internally fused. An input line fuse must always be used.
