Test conditions and notes11
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
  2. 2. Please refer to "DRIVING METHODS OF LED MODULE".
  3. 3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
  4. 4. Tolerance : includes set up tolerance, line regulation and load regulation.
  5. 5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
  6. 6. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
  7. 7. The driver 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. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
  9. 9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
  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

FAQ

Can the NPF-120-48 be installed in outdoor or wet-rated fixtures?

Yes. The NPF-120-48 is IP67 rated, so it resists dust ingress and temporary water immersion. Its working case temperature (Tcase) range of -40°C to +90°C (with load derating per the output load vs temperature curve) makes it compatible with outdoor luminaires and cold-climate installations.

What LED systems does the NPF-120-48 suit at 48V?

The NPF-120-48 supplies 48V DC at 2.5A (120W) in constant-current mode, with a CC range of 28.8–48V. It is a natural fit for 48V LED modules used in industrial high-bay fixtures, outdoor area lighting, and tunnel lighting systems that specify a 48V constant-current driver.

How does the NPF-120-48 compare to the NPF-120-54?

Both are in the ~120W family with identical IP67 protection, 191.0 × 63.0 × 37.5 mm housing, and 0.97 kg weight. The NPF-120-48 outputs 48V at 2.5A (120W, CC range 28.8–48V); the NPF-120-54 outputs 54V at 2.3A (124.2W, CC range 32.4–54V). Choose NPF-120-48 for 48V LED strings and NPF-120-54 for 54V strings.

What is the warranty period on the NPF-120-48?

The NPF-120-48 spec sheet does not state a warranty period; it refers to the warranty statement on MEAN WELL's website (www.meanwell.com). The sheet does give a typical life expectancy of more than 50,000 hours when the case temperature (tc point) is about 75°C or less.
