Criteria A Perf. Criteria A Perf. Criteria A Note: 1. 2. 3. 4. 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. 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. 3 www.PDUKE.com 2015/01/30 LCD20 CHARACTERISTIC CURVE LCD20-48S05 Derating Curve LCD20-48S05 Derating Curve With Heat-sink LCD20-48S05 Efficiency vs. Input Voltage LCD20-48S05 Efficiency vs. Output Load MECHANICAL DRAWING PIN CONNECTION PIN 1 2 3 4 5 6 SINGLE +Vin -Vin Ctrl +Vout Trim -Vout DUAL +Vin -Vin Ctrl +Vout Common -Vout EXTERNAL OUTPUT TRIMMING Output can be externally trimmed by using the method shown below.
