500W off-line 12/24 V power supply

Posted by: NickTch on

Hello,
I am desining 500 Watts power supply using PLC810PG and your RDR-189 as a starting point. The outputs are 24V/15A and 12V/8A. It appears that PIExpert software rev.7.1.5.4 is not ready for this task in reference to the transformer design. What changes to the main transformer specs should I make in order to provide required outputs? Your expert advise will be greatly appreciated.
Thank you,
Nick T

Does your application have airflow?

If not, a good starting point is a transformer whose external surface area is double that of the RD-189. Therefore a core that is ~1.4x longer and ~1.4x wider.
