Description
NPF-40 series is a 40W AC/DC LED driver featuring the dual modes constant voltage and
constant current output. NPF-40 operates from 90
½
305VAC and offers models with different
rated voltage ranging between 12V and 54V. Thanks to the hign efficiency up to 90%, with
the fanless design, the entire series is able to operate for -40
℃
~ +85
℃
case temperature under
free air convection. The entire series is rated with IP67 ingress protection level and is suitable
to work for a variety of applications at dry, damp or wet locations.

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25
℃
of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE".
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. Tolerance : includes set up tolerance, line regulation and load regulation.
5. De-rating may be needed under low input voltages. Please refer to STATIC CHARACTERISTIC sections for details.
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. 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.
8. The model certified for CCC(GB19510.14, GB19510.1, GB17743 and GB17625.1) is an optional model . Please contact MEAN WELL for details.
9. 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.
10. Please refer to the warranty statement on MEAN WELL's website at
