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.\u003c\/p\u003e\n\n\u003cp\u003eHoused 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAlso searched as:\u003c\/strong\u003e adjustable 30a led dimmer switch, 12v pwm brightness controller, 24v heavy duty led dimmer, rotary led controller, 30 amp dc motor speed control.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput \/ Output Voltage:\u003c\/strong\u003e 12V to 24V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Output Current:\u003c\/strong\u003e 30A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Power Output:\u003c\/strong\u003e 360W (at 12V) \/ 720W (at 24V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimming Technology:\u003c\/strong\u003e PWM (Pulse Width Modulation)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Type:\u003c\/strong\u003e Manual Rotary Knob (Fully Adjustable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Material:\u003c\/strong\u003e Rugged Metal \/ Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x H):\u003c\/strong\u003e 86mm × 61mm × 20mm (excluding knob height)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e CE, RoHS\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eCommon Applications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom LED Installations:\u003c\/strong\u003e Dimming long runs of high-power 5050 or 3528 single-color LED strips in architectural or cove lighting setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRV \u0026amp; Marine Lighting:\u003c\/strong\u003e Managing interior cabin lighting brightness in 12V or 24V off-grid battery systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhotography \u0026amp; Studio Lighting:\u003c\/strong\u003e Providing precise, flicker-free adjustable brightness for custom LED softboxes and panel lights.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBasic DC Motor Control:\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eFrequently Asked Questions\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this adjustable dimmer with 110V or 220V AC wall power?\u003c\/strong\u003e\u003cbr\u003e\nA: 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 cuts the total power via PWM and cannot send the data signals required for addressable LEDs or manage multiple color channels.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Why does the metal casing have holes in the sides?\u003c\/strong\u003e\u003cbr\u003e\nA: 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.\u003c\/p\u003e","brand":"Generic","offers":[{"title":"Default Title","offer_id":49669024645358,"sku":"LED-29327","price":249.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/12V24VDC30AAdjustableLEDDimmerSwitch.jpg?v=1790790292","url":"https:\/\/www.tomsonelectronics.com\/products\/12v-24v-dc-30a-adjustable-led-dimmer-switch-pwm-brightness-controller","provider":"Tomson Electronics ","version":"1.0","type":"link"}
