Test conditions and notes13
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μf & 47μf parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Derating may be needed under low input voltage. Please check the static characteristics for more details.
  5. 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. 6. Please refer to "DRIVING METHODS OF LED MODULE".
  7. 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. 8. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
  9. 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. 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. 11. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf
  12. 12. PLN-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).
  13. 13. 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

Can I use the PLN-30-27 for small 27V LED signage?

Yes, this model suits signage applications and provides a 27V constant current output up to 30.24W. It fits 27V lighting loads that stay within the 18.9-27V constant current range and 1.12A output current.

Is the PLN-30-27 suitable for 27V architectural accent lighting?

It can suit 27V accent lighting where the fixture is designed for constant current operation and the load stays within 30.24W. The driver outputs 27V at 1.12A, so the fixture needs to match that electrical requirement.

Can this driver power a 27V lighting load in a compact sign cabinet?

It is a reasonable fit for enclosed signage or lighting assemblies because the housing measures 145.0 x 47.0 x 30.0 mm and is IP64 rated. You still need the connected 27V load to remain within 30.24W and 1.12A.

How much 27V LED strip can the PLN-30-27 support?

The power limit is 30.24W, so the sizing formula is 30.24W divided by your strip's rated power per meter. Check your strip rated power per meter and confirm the strip system matches this driver's 27V output and constant current operating mode.

Can the PLN-30-27 be used outdoors or in damp locations?

Its IP64 rating means the enclosure is suited for environments where dust and water splashes are expected, rather than full immersion. The operating temperature range is -30°C to +50°C (see the derating curve) at 20-95% RH non-condensing, so it is intended for indoor or sheltered outdoor lighting conditions within that range.
