12 V 20 W constant-voltage driver

This ballast delivers a steady 12 V DC output at up to 20 W for low-voltage LED installations. It is built for installers and homeowners who need a Class 2 power supply that can be hard-wired into 120 V switching or dimming circuits. The unit suits projects such as under-cabinet strips, cove lighting and similar 12 V loads.

Class 2 wiring and dimmer compatibility

Because the driver is rated Class 2, it can be run in walls without conduit in many jurisdictions, reducing installation time and material cost. It works directly with 120 V wall switches, low-voltage dimmers and RGB or DMX controllers, so the same power supply serves both simple on-off and colour-changing schemes.

Limited to 20 W total load

The 20 W ceiling means the driver cannot power longer runs or higher-density strips that exceed this budget; additional drivers are required for larger projects. It also lacks built-in surge protection beyond the Class 2 rating, so outdoor or exposed wiring may need supplementary safeguards. California Proposition 65 applies to this product.

Questions about this item

Will the DI-0904 driver need replacement after continuous operation?

The driver is rated for 20 W at 12 V; lifespan depends on thermal environment and load, so plan to inspect connections periodically.

What limit appears first when the driver runs at full 20 W load for hours?

The Class 2, 20 W rating is the hard ceiling; exceeding it triggers protection and shuts the output down.

How hot and loud does the DI-0904 get during all-day use?

It is a sealed, fanless constant-voltage driver, so it runs silently; surface temperature rises with load but stays within Class 2 limits.
