LED Dimmer – DC12V–24V Rotary Knob PWM Controller for Single-Color LED Strips

Product Introduction

The USKYLED PWM LED dimmer provides manual brightness control for compatible DC12V–24V single-color LED strips. A rotary knob lets users adjust the light output directly, making it a practical option for installations that need a simple, accessible control.

Use it with suitable constant-voltage LED strips in cabinets, display shelves, retail fixtures and ceiling coves. The dimmer connects between a matching DC power supply and the LED strip. It controls brightness; it does not replace the power supply.

Design

The controller combines a metal housing with a front-mounted rotary knob. Mounting holes allow the unit to be secured to a suitable surface, while labeled input and output terminals help identify the power supply and LED strip connections.

Position the knob where users can reach it comfortably, and keep the wiring connections accessible for inspection and maintenance.

Main Features

• DC12V–24V operation: For compatible low-voltage, constant-voltage LED strip installations.

• Rotary knob control: Adjust brightness manually at the installation.

• PWM stepless dimming: Vary the light output without selecting fixed brightness levels.

• Automatic memory function: Retains the brightness setting, as stated in the product specification.

• Single-color lighting control: Intended for compatible single-color LED strips, including suitable 5050 and 3528 strips.

• Metal housing: Provides a practical enclosure for the controller.

• Sample and bulk ordering: Available with a minimum order quantity of one piece.

Application

This LED strip dimmer is suitable for compatible lighting installations such as:

• Under-cabinet task lighting.

• Wardrobe and storage shelf lighting.

• Retail shelves and product displays.

• Reception counter accent lighting.

• Ceiling cove lighting.

• Residential decorative strip lighting.

Choose an accessible installation location so the brightness can be adjusted during everyday use.

Size / Options

The current product selection is listed as:

• Model option: LED DIMMER 30A.

• Voltage option: DC12–24V.

• Housing material: Metal.

• Control type: Rotary knob.

Confirm the controller dimensions and mounting-hole spacing before designing a recessed compartment or equipment enclosure. The dimensions shown in the original listing require verification.

Lighting Options

This controller adjusts the brightness of a compatible single-color LED strip. The selected strip determines the light color, color temperature, CRI and light output.

Use a power supply that matches the LED strip voltage. A 12V strip requires a suitable 12V supply, and a 24V strip requires a suitable 24V supply.

This model does not provide independent RGB or RGBW color control, addressable pixel control or tunable-white channel control. Check compatibility before connecting fixtures with built-in drivers or other control electronics.

Installation

1. Disconnect power before starting the installation.

2. Confirm that the power supply voltage matches the LED strip voltage.

3. Connect the DC power supply to the terminals marked IN, observing V+ and V−.

4. Connect the LED strip to the terminals marked OUT, observing V+ and V−.

5. Check all connections and confirm that the load is within the verified controller rating.

6. Secure the controller in an accessible, ventilated position.

7. Restore power and test brightness adjustment with the connected LED strip.

Use the terminal markings on the supplied unit as the wiring reference. Do not connect AC mains directly to this DC dimmer.

Confirm the approved load rating for the selected voltage before installation. The listing identifies the model as 30A and states 360W at both 12V and 24V; the continuous-load limits require confirmation.

Technical Specifications

Project Applications

For cabinet makers, lighting installers and retail fit-out contractors, a rotary dimmer provides straightforward local control of a single-color LED strip.

In display shelving, brightness can be adjusted to suit the products and surrounding light. In cabinets and ceiling coves, the same control allows the lighting level to be changed for different tasks or room settings.

For repeat installations, test a sample with the intended power supply and LED strip before placing a bulk order. Check low-brightness behavior, load performance and access to the control knob.
