MEAN WELL IP67 5 Output Dimmable Constant Voltage LED Driver 12V 40.08W 3.34A PWM Resistance

MEAN WELL NPF-40D-12 LED Driver is a robust IP67 rated 5 output dimmable constant voltage power supply designed for LED lighting applications requiring 12V output at 40.08W power and 3.34A driver current.

This LED driver accepts a universal AC input voltage ranging from 90V to 305V and integrates active PFC function to improve power quality and efficiency up to 90%, minimizing power loss during operation. The unit’s plastic case is fully encapsulated with flame retardant (94V-0) and silicone potting to withstand vibration up to 5G, making it highly suitable for outdoor or demanding industrial environments with dust and moisture exposure.

The NPF-40D-12 supports a versatile built-in 3-in-1 dimming feature allowing control by 0-10V DC signals, PWM input, or variable resistance, making it adaptable for a wide range of LED lighting setups in industrial, commercial, and outdoor applications.

Protection features include short circuit, overcurrent, overvoltage, and overtemperature safeguards to ensure reliable and safe operation across varying conditions. The device operates efficiently under temperatures from -40°C to +70°C, cooled via natural free air convection, and incorporates a class II double insulated design without ground pin for simplified installation.

Its mounting interface consists of screw terminals enclosed in a rugged housing rated IP67, meeting global certifications such as UL8750, CSA C22.2, ENEC, CE, and CB for compliance and quality assurance.

Supports universal AC input voltage range from 90V to 305V. High efficiency up to 90% with low no load power consumption below 0.15W. Waterproof IP67 rating with fully encapsulated design for harsh environments. Equipped with built-in 3 in 1 dimming function: 0-10V DC, PWM signal, or resistance dimming.

Features comprehensive protections including short circuit, overcurrent, overvoltage, and overtemperature. Operates in temperatures ranging from -40°C to +70°C with effective heat dissipation. Class II power unit with double insulation and no FG pin for safe installations.

Enclosed screw mounting type suitable for flexible lighting system integration. Meets multiple international standards and approvals such as UL, CE, ENEC, and CB.

This LED driver is ideally suited for industrial, commercial, outdoor, and architectural LED lighting systems requiring reliable dimmable constant voltage power supply solutions. Explore a broad range of LED drivers and power supplies from MEAN WELL at EnvMart for your lighting projects.
