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.

Product selection and Notes:

1.Please refer to the specifications in detail for selection and use, otherwise the reliability of power supply will    not be guaranteed .

2.All parameters of this specification are measured according to the internal standards of our company.

3.It is suggested that the load power of the power supply should not exceed 80% of the rated power of the power supply.

4.With multi-output power supply, each output circuit must be loaded and used at the same time according to the corresponding ratio .

5.Our company can provide customized products .

6.We reserve the right to change specifications without prior notice .
