DMX to PWM Decoding Series
44 productsTo achieve brightness adjustment, color switching, and control of complex lighting effects for non-addressable (analog) light strips via DMX control, these DMX-to-PWM decoders or converters are what you need.
They translate DMX digital signals into PWM output that standard constant-voltage LED strips can understand — enabling professional-grade DMX control with your existing single-color, CCT, RGB, RGBW, or RGBCCT light strips.
How to Choose the Right DMX Decoder for Your LED Strips?
Before browsing our DMX decoder products, we recommend clarifying the following key factors first — this will help you quickly identify the correct decoder type for your LED strip system and avoid costly compatibility mistakes.
1. Match Your LED Strip Voltage
| LED Strip Type | Decoder Output Voltage |
|---|---|
| Low voltage LED strips | DC12V / 24V / 36V / 48V |
| High voltage LED strips | AC110–120V / 220–240V |
2. Select the Required Output Channels
Channels on DMX-to-PWM decoders typically represent color circuits — not physical LED strips. For example, 1CH outputs a single color change, while 5CH outputs RGBCW or RGBCCT color changes.
If your DMX project involves multiple LED strips and requires 4 sets of RGBW strips, select a DMX-to-RGBW decoder with at least 4x4 (16) channels. Note that each output channel has a current limit.
3. Calculate How Many Decoders You Need
When processing DMX signals for four 5-meter RGBW light strips via DMX-PWM LED decoders, using our UL-certified model (24V, 96 LEDs/m) as an example, each RGBW strip (maximum 153.5 watts, 6.4 amps) occupies 4 color output channels and one output positive terminal.
This means: 6.4A ÷ 4 colors = 1.6A per color channel, so each output channel must be capable of carrying a minimum current of 1.6 amps.
Once you have clarified these related requirements, you are now ready to select the exact DMX-to-PWM decoder model that fits your DMX lighting system. Focusing solely on the Ltech brand? Purchase here.

FAQ About DMX to PWM Decoders
Got questions before you spec your DMX decoder? As an application engineer here for over a decade, I've answered them all. Here are the most common ones that come up before a big install.
A DMX to PWM decoder acts as a translator. It takes the digital signal from a professional DMX lighting console and converts it into a PWM (Pulse Width Modulation) signal that standard, non-addressable LED strips can understand. This is what lets you control simple RGBW or tunable white strips with the same gear used for stage and architectural lighting. Without it, your DMX controller and your analog strips can't talk to each other.
First, match the voltage — if you have a 24V strip, you need a 24V-capable decoder. Second, count your colors to get the channels. A single-color strip needs a 1-channel decoder. An RGB strip needs 3 channels. RGBW needs 4, and RGBCCT needs 5. Finally, check the amperage per channel. Make sure the decoder's output current can handle the total load of the strips you're connecting to it.
Yes, pretty much. All our DMX to PWM decoders use the standard DMX512 protocol, so they'll work with any standard DMX master controller, console, or software interface from any brand. The key is that they speak the same language. For more advanced features like remote device management, look for a decoder and controller that both support RDM, which is an extension of DMX. Our guide covers more on DMX control for LED lighting.
The key is to wire the strips in parallel to the decoder's output terminals, not in series like a long chain. For instance, if you have a 4-channel RGBW decoder and two RGBW strips, you'll connect the R, G, B, W, and V+ wires from *both* strips back to the same R, G, B, W, and V+ terminals on the decoder. Just make sure the combined current of both strips doesn't exceed the decoder channel's amp rating.
This is almost always a PWM frequency issue, especially if you're filming. Low-frequency PWM (around 500 Hz) is fine for the human eye but can show up as flicker or banding on camera. Many of our newer DMX decoders allow you to select a higher PWM frequency—like 2,000Hz (2KHz) or higher—to eliminate this problem completely. Check the product specs for 'High Frequency PWM' if you're lighting a space for video or broadcast.
Absolutely, but you need a specific high-voltage DMX decoder. These models are built to take a 100-240V AC input and output a corresponding high-voltage PWM signal to control High Voltage RGB LED Strips. Do not ever try to use a low-voltage (12/24V) decoder in a high-voltage system. It's extremely dangerous and will destroy the decoder instantly.
It depends on the model. Older or simpler decoders use physical DIP switches where you flip a combination of switches to set the binary value of the starting address. Most of our modern DMX decoders, like the D5 RDM decoder, have a small digital display and buttons. You just press the buttons to set the starting address numerically, which is much faster and less error-prone. If your decoder and controller are both RDM-enabled, you can even set the address remotely from your control software.
