Product Identity

The Elemental LED DI-CV-MW12V40W-277-LPS3R is a 12V 40W constant-voltage LED driver combined with a LO-PRO NEMA 3R wet-location junction box. It is designed for commercial-grade low-voltage lighting installations that require weather-protected enclosure and Class 2 power output.

Installation Requirements

Verify that your supply voltage matches the 120V or 277V input range and that the load does not exceed 40W at 12V. The driver is hard-wired and intended for use with 120V switches, low-voltage REIGN dimmers or RGB/DMX controls. The NEMA 3R enclosure is rated for wet locations, so confirm mounting orientation and conduit entries suit the site conditions.

Bundled Value

The integrated junction box carries UL 2108, UL 508A and UL 1598 certifications, providing a single listed assembly for power supply and environmental protection. This combo eliminates the need to source and mount a separate enclosure, reducing installation time and ensuring code-compliant wet-location performance. California Proposition 65 notice applies.

Questions about this item

Does the combo include both the 12V 40W driver and the NEMA 3R junction box, or must the box be purchased separately?

The combo ships with the LO-PRO NEMA 3R wet-location junction box and the 12V 40W constant-voltage driver already assembled together, so no separate enclosure purchase is needed.

Should I select the 120V or 277V input version for my supply?

The model number includes 277, indicating this unit accepts 120–277V AC input, so it works on either common North American service without a separate variant to choose.

What does the 40W rating mean when the driver is installed inside the sealed box?

The 40W rating is the maximum continuous output the Class 2 driver can deliver at 12V DC while mounted in the UL 2108, UL 508A and UL 1598 certified enclosure, covering the combined load of all connected LED fixtures.
