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