MIL-HDBK-217F Notice2 @Ta=25 ºC, Full load(Ground, Benign, controlled environment) Maximum value at nominal input voltage and full load. Typical value at nominal input voltage and no load. Typical value at nominal input voltage and full load. Test by minimum Vin 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 the +VOUT pin or the -VOUT pin. The ON/OFF control pin voltage is reference to -Vin. The order number please see product standard table. The LED15W meets EN55022 class A and class B only with external components connected before the input pin to the converter. 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, ESR 48mΩ. 1.
