E-Series 40W 12VDC Dimmable LED Driver, Class 2, 120V, NEMA 3R, UL Enclosure

Description

Magnitude Lighting E-Series 40W LED Driver — 12V DC

Magnitude Lighting E-Series LED Driver E40L12DC delivers 40W of Constant Voltage power with a regulated 12V DC output from a 120VAC input. It is forward-phase (TRIAC) dimmable down to 1% and is UL8750 Class 2 for compatible low-voltage LED loads. The compact aluminum housing includes an Integrated Junction Box with knockouts for clean, code-friendly wiring transitions.

Key Features

• Power: 40W maximum load
• Input Voltage: 120VAC ±10%, 50/60Hz
• Output Voltage: 12.0VDC at max load
• Output Current: 3.50A at max load (12VDC)
• Dimming: Forward-phase (TRIAC) dimmable to 1%
• Minimum Load: 8W
• Dimensions: 6.77 in. L x 2.67 in. W x 1.30 in. H
• Enclosure Type: Integrated Junction Box; two 1/4 in. trade size (3/8 in.) knockouts
• IP/NEMA Rating: NEMA 3R
• Class 2 / Certifications: UL8750, Class 2

Physical Design & Installation

Compact aluminum case with powder coat finish and an integrated wiring compartment for line-voltage and low-voltage terminations. Includes two 1/4 in. trade size (3/8 in.) knockouts and flange/key-hole mounting features to support secure installation.

Dimming & Controls

Designed for forward-phase (TRIAC) dimming and can dim down to 1% when paired with compatible TRIAC dimmers. For stable dimming performance, maintain an 8W minimum connected LED load. Input is 120VAC (50/60Hz) and output is constant voltage 12VDC for 12V LED systems.

Performance & Build

High-efficiency design (>90% efficiency at 12VDC) supports lower operating temperature. Protection includes short circuit and over-voltage auto-reset. UL8750 Class 2 construction and NEMA 3R enclosure support demanding installations where a wiring compartment and weather-resistant housing are required.

Typical Applications

• 12V LED tape light runs (STD, HD, and COB types per compatibility chart)
• Architectural accents and coves requiring TRIAC dimming
• Signage and display lighting using 12V constant voltage loads
• Indoor or outdoor installations requiring a NEMA 3R driver enclosure
