Notes

1. The testing condition for the parameter above is:230VAC input, rated load,25
2. Wave test:adopting“A12”double wire for 20MHz,and 0.1uF&uF capacitor short-circuit for interrupting 
3. Error,include the setting error, current regulation and voltage regulation 
4.Linear adjust rate test method: under rated over-load, From low voltage to high voltage 
5.Over-load adjustment rate test method: from 20%-100% rated over-load , others output under 60% .
6.Inner components include power supply, Combined with the electromagnetic compatibility test
