12V 40W Constant Voltage Driver

This constant voltage driver delivers 12V DC at 40W for low-voltage LED lighting systems. It accepts a wide 120-277V AC input range suitable for residential and commercial installations. The unit is designed to pair with 120V switches, low voltage dimmers, and RGB or DMX controls. It ships new in a LO-PRO junction box combo configuration.

Sustained Load Performance

The driver maintains a steady 12V DC output during continuous operation without the voltage spikes common in cheaper alternatives. Its commercial-grade components handle the full 40W rating over long duty cycles typical of architectural lighting. The wide input range accommodates voltage fluctuations on 120-277V AC lines without shutting down. Thermal management is handled through the steel enclosure acting as a heatsink.

Steel Junction Box Enclosure

A rugged steel enclosure houses the driver and provides a code-compliant separation between line voltage and low voltage wiring. The low-profile design fits into tight plenums and ceiling cavities where standard boxes cannot. Hard-wired connections inside the junction box eliminate loose plugs that can fail over time. The combo arrives as a single assembled unit, reducing on-site assembly steps for electricians.

Questions about this item

How much heat does the 40W driver generate when it runs continuously?

The 40W constant-voltage driver produces heat proportional to its load; mount the steel junction box with airflow space to dissipate warmth during all-day operation.

What wiring must already be in place for the 120-277V AC input?

A dedicated 120-277V AC branch circuit with proper grounding and a compatible 120V switch or low-voltage dimmer is required before hard-wiring the driver.

Will the 12V DC output work with my existing 12V LED tape?

Yes, the 12V DC constant-voltage output matches standard 12V LED tape; verify the tape’s total wattage stays at or below 40W.
