Remarks: ① 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. ② 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. |
