| 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. | |||
