MEAN WELL NPF-90 Series Constant Current LED Driver Installation Guide

Power on the LED driver after installation is complete.
Verify that the output voltage and current levels meet the requirements of your LED lighting system.

Maintenance

Regularly check for any signs of damage or overheating.

Clean the LED driver periodically to prevent dust buildup that can affect performance.

FAQ

Q: Can I use multiple LED drivers together?
- A: Yes, you can use multiple LED drivers together, but ensure not to exceed the maximum number specified in the manual for your circuit breaker type.
Q: What should I do if the LED driver overheats?
- A: If the LED driver overheats, immediately disconnect power and allow it to cool down before investigating the cause, which could be inadequate ventilation or overload.

Description

NPF-90 series is a 90W AC/DC LED driver featuring the dual modes constant voltage and constant current output. NPF-90 operates from 90 ~ 305VAC and offers models with different rated voltage ranging between 12V and 54V. Thanks to the hign efficiency up to 91%, with the fanless design, the entire series is able to operate for -40°C ~ +85°C 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.

NOTE

All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
Please refer to “DRIVING METHODS OF LED MODULE”.
Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
Tolerance : includes set up tolerance, line regulation and load regulation.
De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
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.
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)
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.
Please refer to the warranty statement on MEAN WELL’s website at http://www.meanwell.com
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).
