Note:
1.
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 +Vout pin or -Vout pin.
2.
3. The standard modules meet EN55022 Class A without external components and meet Class B with external components.
For further information, please contact with P-DUKE.
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.
4.
CAUTION: This power module is not internally fused. An input line fuse must always be used.
