Test conditions and notes11

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. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
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 fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
11. This product is not suitable for LED lighting applications in China.(It is recommended to use the LPF/NPF/XLG/XLC/XLN series in China)

FAQ

What is the Mean Well PLC-45-12 designed for?

The PLC-45-12 is a 45W 12V power supply intended for LED lighting and moving sign applications. It is a constant-voltage model with built-in constant current limiting, which makes it suitable for applications that need a regulated 12V DC output.

What output does this power supply provide?

This model provides a 12V DC output and is rated for 3.8A current. Its listed power rating is 45.6W, which matches applications that need a 12V supply within that output range.

Does the PLC-45-12 support dimming control?

No. The specified dimming control for this model is none, so it should be selected for applications that do not require built-in dimming functionality from the power supply itself.

What does built-in active PFC mean for this model?

The PLC-45-12 includes an active power factor correction function. Mean Well specifies PF above 0.92 at 115VAC and above 0.9 at 230VAC at full load, which can be relevant for commercial and professional installations where power quality matters.

What protection features are included in the PLC-45-12?

This model includes protection for short circuit, over current, over voltage, and over temperature. These built-in protections help support reliability in demanding LED power applications.

What operating environment is this power supply rated for?

The listed operating temperature range is -30°C to 50°C. Buyers should confirm the final enclosure and application conditions stay within that range, since no additional ingress or outdoor rating is provided here.
