Frequently Asked Questions

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 greater than 0.9 at 75% load or higher, 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.

What warranty is provided for the PLC-45-12?

The stated warranty period for this model is 2 years. That makes it a practical option for buyers who want a branded 12V LED power supply with clearly defined coverage.
