Remark 1. Except for special instructions, the parameters of this specification are measured at 230VAC, rated load and 25c ambient temperature.
2. Ripple and noise measurement method: use a 12 "twisted pair, and the terminal shall be connected in parallel with the capacitance of 0.1uf and 10uF, and shall be measured at 20MHz bandwidth.
3. Accuracy: including the rounding error, linear adjustment rate and load adjustment rate.
4. The power supply shall be regarded as part of the internal components of the system, which shall be confirmed by electromagnetic compatibility with the terminal equipment.
5. The output should be reduced under low input voltage.

Wiring Instruction:
