Constant Voltage LED Driver

The Elemental LED DI-CV-MW12V40W-277 is a 12V 40W Class 2 ballast built for low-voltage LED installations. It suits installers who need a hard-wired commercial grade driver compatible with 120V switches and low voltage dimmers.

Thermal and Power Characteristics

As a constant voltage driver it delivers a steady 12V output up to 40W without the heat spikes seen in constant current alternatives. The Class 2 rating means normal operation stays within recognised low-power limits for simpler code compliance.

Control Compatibility and Use Cases

The unit pairs with RGB and DMX controls so colour-changing or dimmed scenes work from a single power supply. It is not suited for projects that require constant current regulation or drivers rated above the 40W maximum.

Questions about this item

How do I hard-wire the 120-277 V input to the driver and which step is most often missed?

Connect line, neutral and ground to the driver's input leads inside a listed junction box; the step most often missed is securing the ground wire to the box before closing it.

What component will need replacement first and how can I tell?

The internal electrolytic capacitors degrade over time; flickering output or failure to start after the driver has warmed up signals they need replacement.

At what load does the Class 2 limit restrict continuous operation?

The 40 W Class 2 rating caps sustained output at 40 watts; exceeding this triggers the driver's protection circuit and shuts down the output.
