The 12V/24V DC 30A Adjustable LED Dimmer Switch is a heavy-duty power controller designed to smoothly adjust the brightness of single-color LED strips, panels, and custom lighting arrays. Utilizing advanced Pulse Width Modulation (PWM) technology, this dimmer ensures a continuous, flicker-free transition from 0% to 100% brightness without altering the color temperature of your LEDs.

Housed in a rugged, heat-dissipating black metal casing measuring 86mm x 61mm, it is built to handle massive electrical loads safely. With a maximum current rating of 30 Amps, this single module can control up to 360W of lighting on a 12V circuit, or a massive 720W on a 24V circuit. The built-in screw terminal block features a transparent safety cover, making it incredibly easy to wire inline between your DC power supply and your lighting fixtures.

Custom LED Installations: Dimming long runs of high-power 5050 or 3528 single-color LED strips in architectural or cove lighting setups.
RV & Marine Lighting: Managing interior cabin lighting brightness in 12V or 24V off-grid battery systems.
Photography & Studio Lighting: Providing precise, flicker-free adjustable brightness for custom LED softboxes and panel lights.
Basic DC Motor Control: Because it is a high-amperage PWM controller, it can also be used as a simple, adjustable speed controller for brushed DC motors (fans, pumps) up to 30A.

Q: Can I use this adjustable dimmer with 110V or 220V AC wall power?
A: No. This is strictly a low-voltage DC controller. Connecting it directly to AC mains power will instantly destroy the module and pose a severe fire hazard. It must be wired after your AC-to-DC power supply transformer.

Q: Will this work with RGB or addressable (WS2812B) LED strips?
A: No. This is a single-channel dimmer designed only for single-color LED strips (e.g., solid white, warm white, or solid blue). It cuts the total power via PWM and cannot send the data signals required for addressable LEDs or manage multiple color channels.

Q: Why does the metal casing have holes in the sides?
A: Pushing 30 Amps of current generates heat. The casing acts as a heatsink, and the side slots allow for passive airflow to keep the internal MOSFETs cool during continuous, high-load operation.
