Mean Well PLC-30-9 Power Supply 30W 9V - PFC

The PLC-30-9 is designed for equipment that needs a regulated 9V DC supply up to 3.3A. It is commonly suited to low-voltage LED and industrial power applications where a compact 30W class supply with active power factor correction is preferred.

This model is rated for 29.7W output with a nominal 9V DC output and 3.3A rated current. It also supports universal AC input and includes active PFC, with a stated power factor above 0.9 at 75% load or higher.

No. The listed dimming control for the PLC-30-9 is none, so it should be selected for applications that require a fixed-output power supply rather than integrated dimming functionality.

The PLC-30-9 is a constant-voltage model with a built-in constant current limiting circuit, described as C.V. plus C.C. mode. It also includes protection for short circuit, over current, over voltage, and over temperature.

This model is rated for operation from -30°C to 50°C and uses free air convection for cooling. Its isolated plastic case and Class II design make it suitable for enclosed power supply applications where fanless operation is preferred.

A key differentiator is its built-in active PFC, which is not always included on lower-complexity 9V power supplies. The PLC-30-9 also combines adjustable output voltage and current level with Class 2 / LPS-related safety positioning and up to 89% efficiency.
