Maximum value at nominal input voltage and full load. 3. Typical value at nominal input voltage and no load. 4. Single Outputs: 3.3-15V measured with 1µF M/C X7R and a 10µF T/C, 24V measured with 2 pcs of 6.8µF/50V X7R MLCC Dual Outputs: 12, 15V measured with 1µF M/C X7R and a 10µF T/C for each output, 24V measured with a 4.7µF/50V X7R MLCC for each output 5. Test by minimum Vin and constant resistive load. 6. 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 +Vout pin or the –Vout pin. 7. The ON/OFF control pin is referenced to –Vin. To order Negative Logic Remote ON/OFF add the suffix “R” to the model number. 8. Heatsink is optional and P/N: 7G-0047C-F. See “Product Standard Table” on page 5 for ordering information. 9. EN55022 1) To meet Class A the module needs no external components 2) To meet Class B please refer to the filter suggestion on page 4. 10. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The filter capacitor suggested is Nippon chemi-con KY series, 220μF /100V, ESR 48mΩ. 11. There are several different options available for this series. Please see the “Product Standard Table” on page 5 for all options and ordering information. CAUTION: This power module is not internally fused. An input line fuse must always be used.
