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 output does the Mean Well PLC-30-48 provide?
The PLC-30-48 is a 30.24W power supply with a 48V DC output and a rated current of 0.63A. This model also includes constant current limiting in C.V.+C.C. mode, which can help in applications that need controlled output behavior.
Is the PLC-30-48 suitable for LED driver applications?
Yes. This model is positioned for LED driver use and combines constant voltage output with built-in constant current limiting. That makes it relevant for 48V LED power applications where buyers want a dedicated LED-focused power supply rather than a generic supply.
Does the PLC-30-48 support dimming control?
No. The spec sheet does not list a dimming function for the PLC-30-48. 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.
What makes the PLC-30-48 different from basic non-PFC power supplies?
The PLC-30-48 includes PFC, with a typical power factor of PF>0.95 at 115VAC and PF>0.9 at 230VAC at full load. It is also specified at 85.5% typical efficiency, which helps distinguish it from simpler low-power supplies that do not include power factor correction.
What operating environment is this model rated for?
The PLC-30-48 is rated for ambient temperatures from -30°C to 50°C (refer to the derating curve) at 20-95% RH non-condensing, so buyers should match it to applications that stay within that temperature range.
What protection and warranty coverage does the PLC-30-48 include?
This model includes short circuit, over current, over voltage, and over temperature protection. The datasheet does not state a warranty term; it specifies an MTBF of 625.5K hrs min. (MIL-HDBK-217F, 25°C), useful for comparing lifecycle risk across 48V power supplies.
