(see the ?product options? table on page 5 for suffix options). 8. the power module can operate in a variety of thermal environments; however, sufficient cooling should be provided to help en sure reliable operation. 9. the jf series meets en55022 class a and class b only with external components connected to the input pins of the converter. 10. an external filter capacito r is required if the module has to meet en61 000-4-4 and en61000-4-5. th e filter capacitor sugges ted is nippon chemi-con ky series, 220 f/100v, esr 48m ? . caution: these power modules are not internally fused. an input line fuse must always be used. output adjustability output voltage adjustment allows the user to increase or decrease the output voltage set point of a module. this is accomplishe d by connecting an external resistor between the trim pin and either the +output or -output pins. with an external resistor between the trim and -output pin, the output voltage set point increases. with an external resistor between the trim and +output pin, the output voltage set point decreases. the external trim resistor needs to be at least 1/16w. trim up equation trim down equation ?? , u oup gl rh vlk ?? ? ??? ?? ?? ?? ?? ?? ?? , , o down d o o down vlg rh vv ?? ?? ??? ?? ? ?? ?? -input +input -output +output trim r u r d model g h k l jfxxs3.3-3500 5110 2050 0.8 2.5 jfxxs5-3000 5110 2050 2.5 2.5 jfxxs12-1250 10000 5110 9.5 2.5 jfxxs15-1000 10000 5110 12.5 2.5
