MEAN WELL NPF-40D Series 40W Single Output LED Driver User Manual

NPF-40D series is a 40W AC/DC LED driver featuring the constant current mode output. NPF-40D operates from 90-‘305VAC and offers models with different rated voltage ranging between 12V and 54V. Thanks to the high efficiency up to 90%, 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. NPF-40D is equipped with the 3 in 1 dimming function so as to provide the design flexibility for LED lighting system.

NOTE	All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25 ℃ of ambient temperature. 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 standby power consumption is specified for 230VAC. 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. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75C or less. Please refer to the warranty statement on MEAN WELLs website at httpi/www.meanwell.com The ambient temperature derating of 3.5 ℃ /1000m with fanless models and of 5 ℃ /1 000m with fan models for operating altitude higher than 2000m(6500ft). 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 ※ Product Liability Disclaimer : For detailed information , please refer to https://www.meanwell.com/serviceDisclaimer.aspx

DRIVING METHODS OF LED MODULE

※ This series works in constant current mode to directly drive the LEDs.

Typical LED power supply I-V curve

DIMMING OPERATION

※ 3 in 1 dimming function

Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-: 0 ~ 10VDC, or 10V PWM signal or resistance.
Direct connecting to LEDs is suggested. It is not suitable to be used with additional drivers.

Dimming source current from power supply: 100 A (typ.) μ

Applying additive 0 ~ 10VDC

“DO NOT connect “DIM- to Vo-”

Dimming input: Additive voltage

Applying additive 10V PWM signal (frequency range 100Hz ~ 3KHz):

DO NOT connect “DIM- to Vo-”

Duty cycle of additive 10V PWM signal dimming input
◎ Applying additive resistance:

“DO NOT connect “DIM- to Vo-”

(N=driver quantity for synchronized ) dimming operation Dimming input: Additive resistance

Note :

Min. dimming level is about 6% and the output current is not defined when 0%< out<6%. I

The output current could drop down to 0% when dimming input is about 0k or 0Vdc, or 10V PWM signal with 0% duty cycle.
