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

E40R12DC is a 40W Magnitude Lighting LED Driver designed for Constant Voltage 12V DC loads from a 120V AC source. It supports forward-phase (TRIAC) dimming down to 1% and is Class 2 rated. The driver uses a compact aluminum, IP67 enclosure with flying leads and no Integrated Junction Box.

Key Features

• Power: 40W maximum load
• Input Voltage: 120VAC ± 10%, 50/60Hz
• Output Voltage: 12.0VDC at max load
• Output Type: Constant Voltage, single channel
• Dimming: Forward-phase (TRIAC) dimmable to 1%
• Minimum Load: 8W required for smooth dimming
• Dimensions: 4.92 in. L x 2.20 in. W x 0.79 in. H
• Enclosure Type: IP67 anodized aluminum housing with flying leads; no junction box
• IP Rating: IP67
• Certifications: UL8750 Recognized; UL 879; Class 2

Physical Design & Installation

Built in an anodized aluminum housing for compact, concealed mounting. This model uses flying leads for primary and secondary connections and does not include an Integrated Junction Box or wiring compartment; plan for code-compliant splicing in an appropriate junction box. Mounting is via flange holes (one full-hole and one half-hole flange mount).

Dimming & Controls

Designed for forward-phase (TRIAC) wall dimmers and can dim down to 1% when paired with compatible controls. For smooth dimming performance, maintain an 8W minimum load on the driver output. Output is 12V DC constant voltage for compatible 12V LED tape and fixtures.

Performance & Build

High-efficiency design (>90% listed) supports lower operating temperature. Protection includes auto-reset short circuit and over-voltage protection. Rated Class 2 and sealed to IP67 for wet-rated installations.

Typical Applications

• Wet-location LED tape lighting power supplies
• Outdoor accent and landscape lighting (12VDC systems)
• Sign and channel letter power applications
• Architectural cove and undercap lighting where TRIAC dimming is required
