Note:

1.

Converter can meet the railway T2 and TX temperature requirement.

T2: -40 ºC ~ +70 ºC as all models; TX: -40 ºC ~ +85 ºC as power derating to 55% output power.

2.

The standard modules meet EMI Class A or Class B with external components. For further information, please contact with P-DUKE.

3.

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: : 24Vin/48Vin Nippon chemi-con KY series, 220µF/100V

: 110 Vin Nippon chemi-con KXJ series, 150µF/200V

CAUTION: This power module is not internally fused. An input line fuse must always be used.
