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. | |
