Unless otherwise specified, all specifications are measured at 230VAC input, rated negative cut, and 25°C ambient temperature.

Ripple and noise measurement method: the measured end is connected with a 0.1uF+10uF capacitor, the oscilloscope is set to 20MHZ bandwidth, the probe is uncapped for testing, and the full load is 25℃.

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

The output power should be reduced when the input voltage is lower than 200VAC.
