Remarks

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

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.
