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. |
