Remarks

 

1. Except for special instructions, the parameters of this specification are measured at 230VAC input, rated load and 25C.

2. Measurement of ripple and noise: Using a  12” twisted pair, and the terminal has two capacitors, 0. 1uF and 10uF in parallel. Measured at 20MHz bandwidth.

3. Accuracy: Including errors, linear adjustment rate and load adjustment rate.

4. The power supply should be regarded as part of the components in the system, and electro-magnetic compatibility related confirmation should be carried out with the terminal equipment.

5. Reduced output is required under low input voltage. Please refer to the reduction graph.
