Note
MIL-HDBK-217F @Ta=25 ºC, Full load.
Typical value at nominal input and no load.
Typical value at nominal input and full load.
Test by minimum input and constant resistive load.
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: -40 ~ +70 as all models , TX: -40 ~ +85 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. The RED20W series 24VDC & 48VDC input standard module meet EN55022 & EN55011 Class B without external components, 110VDC input meet
EN55022 Class A without external components and meet Class B with external components. For more detail information, please contact with P-DUKE.
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: 24VDC & 48VDC input: Nippon chemi-con KY series, 220µF/100V.
110VDC input: Rubycon BXF series, 100µF/250V.
CAUTION:
This power module is not internally fused. An input line fuse must always be used.
