| Remarks | 1) Measurement of ripple and noise: Using a 12'' twisted-pair line with a capacitor of 0.1uF and 47uF in parallel at the terminal,the measurement is carried out at 20MHz bandwidth.2)Efficiency is tested at the input voltage of 230VAC. rated load and 25℃ ambient temperature.Accuracy: including setting error,linear adiustment rate and load adiustment rate.Test method of linear adiustment rate: testina from low voltage to hiah voltage at rated load adiustment rate test method: from 0%-100% rated load .The start-up time is measured in the cold start state. and the fast frequent switch machine may increase the startup time.When the altitude is above 2000 meters, the operating temperature should be lowered by 5/1000 | |||
