Notes:
|
1. Unless specially indicated, all data are taken under 230VAC input, rated load and 25℃ environment temp.
|
|
2.Ripple and noise: measured with a 12” double ripple cord connected in parallel with a 0.1μF and a 47 μF capacitor on 20MHz
bandwidth.
|
|
3.Accuracy: including preset errors, linear adjustment rate and load adjustment rate.
|
|
4.Linear adjustment: taken under rated load from low voltage to high voltage.
|
|
5.Load adjustment: taken under 0~100% of rated load.
|
|
6. Power supply is taken as part of the whole system, and needs to be confirmed with terminal instruments for EMC.
