1.3 Considerations

The reference design shows an example of an isolated AC/DC transformer that converts 85VAC–264VAC to 24VDC and 5VDC with AC zero crossing. This design can be used in CPU (PLC Controller), Industrial AC-DC ,and Refrigerator and freezer designs as well as various other electronic systems. This design provides overcurrent protection (OCP) and short-circuit protection (SCP) to improve the reliability.
