Test conditions and notes10
  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 0.1uf & 47uf 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 characteristic for more details.
  5. 5. Please refer to "DRIVING METHODS OF LED MODULE".
  6. 6. 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)
  7. 7. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
  8. 8. 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.
  9. 9. 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).
  10. 10. 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

FAQ

Can I use the PLN-20-24 for a short 24V LED strip run in retail lighting?

It can be used with 24V lighting loads up to 19.2W and 0.8A, within the 18-24V constant-current range. For retail lighting, confirm the 24V LED product is compatible with constant-current operation and that total load stays within the driver's rating.

Is the PLN-20-24 a good choice for small illuminated signage?

Yes, it can suit small illuminated signage. Its 24V output and 19.2W capacity make it appropriate for smaller compatible sign lighting sections rather than higher-power installations.

Can this model power compact 24V accent or cove lighting?

It can be used for compact 24V lighting loads if the total demand does not exceed 19.2W or 0.8A. The IP64-rated case also supports use in locations where dust and splashing water are expected.

How much 24V LED strip can the PLN-20-24 support?

Calculate maximum strip length as 19.2W divided by the strip's rated watts per meter. Check your strip rated power per meter, and make sure the strip is a 24V load that is compatible with this driver's operating mode.

Is the PLN-20-24 suitable for damp or outdoor environments?

The IP64 rating means it is built for dust protection and splashing-water exposure, which is useful in damp or semi-exposed environments. It should be operated within its specified -30°C to +60°C temperature range.
