Test conditions and notes12

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. PLC-30-9 is used for any light source that exempt from the ErP-Directive (EU) 2019/2020 requirement, for example this model could be use for signalling products (including, but not limited to road-, railway-, marineorair traffic-signalling , traffic control or airfield lamps).
12. 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 output rating of the Mean Well PLC-30-12?

The PLC-30-12 is a 30W power supply with a 12V DC output and a rated current of 2.5A. It is designed as a constant-voltage unit with built-in constant current limiting. This makes it suitable for 12V loads that need a stable DC supply within that power range.

What kinds of applications is the PLC-30-12 typically used for?

This model is generally suited to low-power 12V LED lighting and similar DC applications that fit within its 30W, 2.5A rating. Its constant-voltage design makes it a practical choice for equipment that expects a regulated 12V DC source. Buyers usually consider it for compact indoor systems where stable output and protected operation matter.

What makes the PLC-30-12 different from a basic 12V power supply?

The PLC-30-12 includes power factor correction, with a typical PF>0.95 at 115VAC and PF>0.9 at 230VAC at full load, which is a stronger feature set than many basic 12V supplies. It also has built-in short circuit, over current, over voltage, and over temperature protection. In addition, it offers adjustable output voltage and current level plus C.V.+C.C. operation for more controlled performance.

Can the PLC-30-12 be used in demanding temperature conditions?

This model is rated for operation from -30°C to 50°C. That gives it a wider usable temperature range than many light-duty indoor supplies. Buyers should still ensure the surrounding equipment stays within the product's specified operating conditions.

Is the PLC-30-12 a good fit when efficiency and compliance features matter?

Yes. The PLC-30-12 offers 82.5% typical efficiency and includes PFC, which can be important in commercial and professional lighting applications. It also carries UL1310, TUV EN61347 and CAN/CSA safety approvals, is marked SELV, and has 3.75KVAC input-to-output withstand voltage.
