Maximum value at nominal input voltage and full load. 3. Typical value at nominal input voltage and no load. 4. Typical value at nominal input voltage and full load. 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 voltage is reference to -Vin. The order number please see product standard table. 8. Heat sink is optional and P/N:7G-0047C-F 9. The LCD15 series can meet EN55022 Class A with parallel external capacitors to the input pins.
