Remarks

Ripple and noise measurement method: use a 12 "twisted pair, and connect 0.1uF and 47uF capacitors in parallel at the terminal, and measure at 20MHz bandwidth. The efficiency is tested at an input voltage of 230VAC, rated load, and an ambient temperature of 25 . Accuracy: including setting error, linear adjustment rate and load adjustment rate. Linear regulation test method: under rated load from low voltage to high voltage test load regulation test method: from 0% - 100% rated load. The start-up time is measured under the cold start state. The quick and frequent switch on and off may increase the start-up time. When the operating altitude is higher than 2000m, the operating environment temperature needs to be reduced by 5 / 1000m
