Minimum AC Input Voltage
Maximum AC Input Voltage
AC Mains Frequency
Output Voltage (main) measured at the end of output cable (For
CV/CC designs enter typical CV tolerance limit)
Power Supply Output Current (For CV/CC designs enter typical
CC tolerance limit)
Enter "YES" for CV/CC output. Enter "NO" for CV only output
Enter the resistance of the output cable (if used)
Output Power (VO x IO + dissipation in output cable)
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
Enter 'YES' for a clampless design. Enter 'NO' if an external
clamp circuit is used.
Efficiency Estimate at output terminals. For CV only designs
enter 0.7 if no better data available
