NOTE	1.  All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature. 2.  Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3.  Tolerance : includes set up tolerance, line regulation and load regulation. 4.  Derating may be needed under low input voltage. Please check the static characteristics for more details. 5.  Output voltage can be adjusted through the SVR1 on the PCB ; limit of output constant current level can be adjusted through the SVR2 on the PCB. 6.  Please refer to “DRIVING METHODS OF LED MODULE”. 7.  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 manufacturers must re-qualify EMC Directive on the complete installation again. 8.  Direct connecting to LEDs is suggested, but is not suitable for using additional drivers. 9.  To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains. 10.  The ambient temperature derating of 3.5℃/1000m with finless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft). ※ Product Liability Disclaimer: For detailed information, please refer to https://www.meanwell.com/serviceDisclaimer.aspx                                File Name:PLC-45-SPEC  2021-12-24
