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 applications is the Mean Well PLC-30-9 best suited for?

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.

What are the main electrical ratings of the PLC-30-9?

This model is rated for 29.7W output with a nominal 9V DC output and 3.3A rated current. It also supports universal 90-264VAC input and includes PFC, with a typical power factor of PF>0.95 at 115VAC and PF>0.9 at 230VAC at full load.

Does the PLC-30-9 support dimming control?

No. The spec sheet does not list a dimming function for the PLC-30-9. Its output voltage is set with SVR1 and its constant-current limit with SVR2 on the PCB, so choose a dimmable driver if your project needs dimming.

How does the PLC-30-9 handle load protection and output regulation?

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.

What operating environment is the PLC-30-9 designed for?

This model is rated for operation from -30°C to 50°C (refer to the derating curve) at 20-95% RH non-condensing. Its compact 160 x 46 x 30mm size suits enclosed power supply applications within those limits.

What differentiates the PLC-30-9 from simpler 9V power supplies?

A key differentiator is its built-in 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 short circuit, over current, over voltage and over temperature protection and 80% typical efficiency.
