Remarks


1. Unless otherwise specified, all specifications and parameters are measured under 230VAC input, rated load and 25 ℃ ambient temperature.

2. Measurement method of ripple and noise: a 12 "twisted pair is used, and 0.1uF and 47uF capacitors are connected in parallel at the terminal. The measurement is carried out at 20MHz bandwidth.

3. Accuracy: including setting error, linear adjustment rate and load adjustment rate.

4. When the input voltage is DC voltage, please connect the positive pole of the input voltage to the mark "L" of the terminal block and the negative pole to the mark "n" of the terminal block.

5. When the operating altitude is higher than 2000m (6500ft), the operating environment temperature should be reduced by 5 ℃ /1000m.

6.The power supply shall be regarded as a part of the components in the system, which shall be confirmed in combination with the terminal equipment.
