Notes

1. All parameters NOT specially mentioned are measured at 230VAC input , rated load and 25℃of ambient temperature.

2. Tolerance: includes set up tolerance, line regulation and load regulation .

3. The power supply 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 manufactures must be-qualify EMC Directive on the complete installation again.
