Maximum AC Input Voltage
AC Mains Frequency
Output Voltage (main) (For CC designs enter upper
CV tolerance limit)
Power Supply Output Current (For CC designs enter
upper CC tolerance limit)
Voltage drop across sense resistor.
Enter the resistance of the output cable (if used)
Output Power (VO x IO + CC dissipation)
Enter 'BIAS' for Bias winding feedback and 'OPTO' for
Optocoupler feedback
Enter 'YES' to add a Bias winding. Enter 'NO' to
continue design without a Bias winding. Addition of
Bias winding can lower no load consumption
!!! Caution. For designs above 2 W and no Bias
winding, Verify peak Drain Voltage and EMI
performance
