 For example, with respect to UL60950-1, the following contents are required.

1. Rated voltage or the rated voltage range
2. Rated frequency or the rated frequency range (excluding DC converter)
3. Rated current
4. Manufacturer name, trademark or other distinguishable marks
5. Model name or type classification

2. Difference between input voltage range indicated on the name plate and spec.

 The input voltage range presented in the specifications shows the range in which the power supply can be used and its electrical characteristics will be guaranteed.
 On the other hand, the name plate on the power supply indicates the rated output voltage range which is approved by safety agency but the power supply can be used at the input voltage range presented in the specifications.
