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 are the main electrical ratings of the Mean Well PLC-30-27?

The Mean Well PLC-30-27 is rated for 30.24W output power with a 27V DC output and 1.12A rated current. It also includes power factor correction and is described as operating in C.V.+C.C. mode with adjustable output voltage and current level.

What type of applications is the PLC-30-27 designed for?

This model is intended for LED driver and power supply applications where a 27V output is required. Its constant voltage operation with built-in constant current limiting makes it relevant for commercial and industrial lighting-related use cases.

What distinguishes the PLC-30-27 from a basic non-PFC power supply?

The PLC-30-27 includes built-in PFC, with a typical power factor of PF>0.95 at 115VAC and PF>0.9 at 230VAC at full load. Compared with a basic non-PFC unit, that makes it better suited to applications where power quality and compliance-related performance matter.

What operating temperature range is supported by the PLC-30-27?

This model is specified for operation from -30°C to 50°C. That range makes it suitable for demanding indoor or protected-environment applications where ambient conditions can vary significantly.

Is the PLC-30-27 a constant voltage power supply or a constant current LED driver?

The PLC-30-27 is described as operating in C.V.+C.C. mode, meaning it is a constant voltage power supply with built-in constant current limiting behavior. For buyers, that means the unit is centered around its 27V output while adding current-limiting protection characteristics.

What protection and enclosure features does the Mean Well PLC-30-27 include?

This model measures 160 x 46 x 30mm and has 3.75KVAC input-to-output withstand voltage. The listed protections include short circuit, over current, over voltage, and over temperature, and it carries UL1310, TUV EN61347 and CAN/CSA safety approvals.
