I bought it to plug in LEDs and then run a DMX-to-USB adapter to connect it to my computer. You need to wire the DMX cable into this decoder manually, but it's pretty easy as there's only 3 wires. Just look online for some diagrams and try it out. I got it right the first time. After connecting a power supply I was able to immediately get the LEDs to respond to my LightKey DMX software. For a power supply, I would recommend 12V DC 30A 360W Metal Regulated Switching Power Supply . For a cheap DMX-to-USB, you can use DMXking ultraDMX Micro USB DMX adapter/dongle , though for more complicated setups you'll need something more. The unit is also a lot smaller than I expected. It's about the size of a CD case, which is quite small. All the green connectors are very sturdy and are removable as well. So you can remove the 4-wire female connectors, and then put it into another slot to easily exchanged between each of the 8 LED channels without having to unplug the wires. The wires plug in using a screwdriver to loosen the connector, insert wire, and then tighten the screw. It's very sturdy. Sure, it would be nice if it had an actual DMX plugin instead of having to wire it yourself. But even a beginner should be able to screw 3 wires in (check the INPUT V+/V- section to see where I'm talking about, you have to strip your power wires and then plug them in there. Anyways, love the unit. Does exactly what it's supposed to do, and the FUN mode (DIP Switch 10) makes it really easy to test out the setup. Review: Can handle a lot of current. - This thing can pass a lot of current. I hooked up seven 5m strips and put them all at full brightness. This thing got a little warm. I blew a 15 amp fuse at 12v, and one 30 amp fuse held fine. So - that's probably around 20 amps. That is a LOT of current. So - make sure that your supply lines are up to the task. I used two 12 gauge wires in parallel from a car battery. At that current, the box was slightly warm to the touch. I pulled the lid and looked up the transistors inside. They are N channel mosfets rated at 60 amps. So - you should be fine. I used this in conjunction with a TinkerKit DMX master shield also here on desertcart. This was my third iteration of trying to control a lot of strips with an Arduino. This combo worked like a charm right away. UPDATE: I think people may be confused by the documentation, which is very light. The most important thing is identifying switch 10, making sure you understand the "ON" direction, and turning Switch 10 "OFF". When Switch 10 is "OFF" the controller is in receive mode to accept DMX commands. When Switch 10 is ON, the other dip switches make led strips blink in predefined automatic ways and there is some method to their madness - but the controller does not accept DMX commands in that mode. In DMX mode (again, switch 10 is OFF) the remaining dip switches set the first DMX address of the device. Often, this will be "1", in which case the only dip switch in the ON position should be switch 1. Each RGB channel of each strip has its own DMX channel. So, the first LED strip will be red, channel 1; green, channel 2; blue, channel 3 - etc. If you hook up a second unit, you can daisy chain the DMX signal from the DMX Out of the first device to the DMX In of the second device. In this scenario you would set the initial DMX address of the second device to 25 (the first device takes addresses 1-24). You would do this be turning on dip switches 1, 4, and 5. Those represent the binary number 1+8+16 = 25. I have done this with two units connected together and it worked flawlessly. ## Features - Automatically adapt to DC12V-24V - Standard DMX512 Signal - 3A each channel max 72A - RGB 24 Channel,8 group ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00Q1N1NVK | | Actuator Type | Push Button | | Best Sellers Rank | #17,215 in Musical Instruments ( See Top 100 in Musical Instruments ) #198 in Stage Lighting Accessories | | Brand Name | HOHTAA | | Circuit Type | 24-way | | Color | Black | | Connectivity Protocol | Wi-Fi | | Connector Type | Screw in | | Contact Material | Metal | | Contact Type | Normally Open | | Control Method | Touch | | Controller Type | Push Button | | Current Rating | 3 Amps | | Customer Reviews | 4.2 4.2 out of 5 stars (101) | | International Protection Rating | IP54 | | Item Dimensions | 4.33 x 3.15 x 1.1 inches | | Item Weight | 16 ounces | | Manufacturer | Colorful-UK | | Material Type | Metal | | Model | 4348131067 | | Mounting Type | DIN Rail Mount | | Number of Items | 1 | | Number of Positions | 24 | | Operating Voltage | 24 Volts | | Operation Mode | ON-ON-ON | | Switch Type | Power Diode | | Terminal | Screw | | UPC | 707837307080 | | Unit Count | 1.0 Count | | Wattage | 1728 watts | ## Product Details - **Brand:** HOHTAA - **Connector Type:** Screw in - **Contact Type:** Normally Open - **Current Rating:** 3 Amps - **Item dimensions L x W x H:** 4.33 x 3.15 x 1.1 inches - **Material:** Metal - **Operating Voltage:** 24 Volts - **Operation Mode:** ON-ON-ON - **Switch Type:** Power Diode - **Terminal:** Screw ## Images ![High Power 24 Channel 3A/CH DMX512 Controller Led Decoder Dimmer for Project - Image 1](https://m.media-amazon.com/images/I/71JIUXaAmuL.jpg) ## Questions & Answers **Q: Is each group on this box individually addressable for individual strip control? if i had eight 5m led strips connected would each be controllable?** A: This box takes up 24 channels total. Each Led strip takes 3 channels. So you can have 8 led strip total running there own dmx address so each of the 8 led strip that you connect can have different colors. When you have this box, you can set the starting dmx address. For example, I can set this light to start at dmx channel 100 (or whatever channel you want it to start) and then it will use channels 100-124 (100-102 for first led strip, 103-105 for second led strip And so on). **Q: Where would I locate a 72-80 amp 12vdc power supply for this device? Thanks.** A: Well, that's gonna be difficult and expensive. But the good news is, you only need to supply as much current as you're going to use. We only use 1 LED tape (3A draw) on each output and so we only needed a 24A supply. I found some here on Amazon that are 12v 30A units for $24. **Q: Have you had trouble addressing the device and having it respond to the dmx signal? since the documentation is almost none.** A: I have had no problems addressing this device or sending it DMX data. If you have not already done so, suggest you test connectivity device by setting its DMX address = 01 . To configure this address only the DIP switch labeled "1" is set to the down position. All others must be up. **Q: What power supply would I need in order to use the full 72 amps that this is claimed to be capable for this device?** A: According to the manual, this thing can only handle 24 amps total, or 1 amp per channel/3 amps per output. The specs are showing wrong on Amazon. We wired ours up to a 12v 30a Dc power supply and it works good for us. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works perfect - you probably won't need another DMX decoder *by A***R on February 27, 2016* This unit works great.

If you need this style decoder, perhaps go with a different brand. Lights stay dimly lit even when In OFF position. Terminator didn't help either. Update: Received 2 more replacements after that also have this issue. My only working one was bought early 2025 so there must be some batches that are defective from the factory. Just be aware. ## Frequently Bought Together - High Power 24 Channel 3A/CH DMX512 Controller Led Decoder Dimmer for Project - econoLED 12V Flexible SMD 5050 RGB LED Strip Lights, LED Tape, Multi-Colors, 300 LEDs, Non-Waterproof, Light Strips, Color Changing, Pack of 16.4ft/5m Strips - C-able 100ft(30.5m) 22 AWG 4Pin RGB Wire Extension Cable with Spool, Led Lights Wires Strip Extend Wire for 5050 3528, with 8PCS RGB Led Strip Connectors --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/11773658-high-power-24-channel-3a-ch-dmx512-controller-led-decoder](https://www.desertcart.co.uk/products/11773658-high-power-24-channel-3a-ch-dmx512-controller-led-decoder) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
