The reference transformer design which will be sent to you later is derived from the calculation based on your specifications; it is not confirmed by actual operations.
It should be noted that the transformer design shows the reference value, and it does not assure the actual operation on your device or system. In actual design, please make adjustments after confirming the operations on your device or system.
