Test conditions and notes10

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
3. 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.
4. The standby power consumption is specified for 230VAC.
5. 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)
6. 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.
7. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
8. 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).
9. 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
10. 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.

FAQ

What dimming signals are supported by the NPF-90D-42?

The NPF-90D-42 has built-in 3-in-1 dimming that accepts a 10V PWM signal, 0–10VDC, or resistance between DIM+ and DIM-, all natively integrated without external dimming accessories.

Can the NPF-90D-42 power dimmable 42V LED fixtures in outdoor architectural lighting of a commercial building facade?

The NPF-90D-42 delivers 90.3W at 42V with a constant current of 2.15A and a CC voltage range of 25.2–42V, making it appropriate for 42V LED facade lighting modules where dimming for evening scenes or energy management is needed. Its IP67 rating supports direct outdoor mounting.

How does the NPF-90D-42 compare to the NPF-90D-36 and NPF-90D-48?

All three are 90W dimmable IP67 drivers with 3-in-1 dimming and the same 171.0 × 63.0 × 37.5 mm form factor, differing in output voltage: NPF-90D-36 is 36V at 2.5A (CC range 21.6–36V), NPF-90D-42 is 42V at 2.15A (CC range 25.2–42V), and NPF-90D-48 is 48V at 1.88A (CC range 28.8–48V).

Is the NPF-90D-42 appropriate for outdoor use in high-rainfall regions?

Yes. The NPF-90D-42 is IP67 approved for dust protection and resistance to temporary water immersion, and works at a case temperature (Tcase) of -40°C to +85°C with load derating at higher temperatures, covering humid, high-rainfall outdoor environments.

Does the NPF-90D-42 require an earth ground connection?

No. The NPF-90D-42's input cable has only two conductors, AC/L (brown) and AC/N (blue), with no earth (FG) wire, so there is no ground connection to make.
