Note:

All parameters not specifically mentioned were measured at 230VAC input, rated load, and an ambient temperature of 25 ℃.

2. Measure ripple and noise at a bandwidth of 20MHz using a 12 "twisted pair cable with 0.1uf and 47uf parallel capacitors terminated.

3. Tolerance: including setting tolerance, line adjustment, and load adjustment.
