1. All parameters NOT specially mentioned are measured at 230VAC input, rated and 25 of ambient temperature.current ℃
2. Please refer to " ".OUTPUT CURRENT SETTING
3. De rating may be needed under low input voltages. Please .- refer to STATIC CHARACTERISTIC sections for details
4. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
5. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the
complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again.
6. The DA type power supply is less efficient than the typical efficiency in specification by 2%.
7. This series meets the typical life expectancy of >50000 hours of operation when Tcase, particularly point (or TMP, per DLC), is about 70 or less.℃tc
