Ltech D4-F Constant Voltage 4 Channel DMX/RDM Decoder, 12-24V, 5A p...
Log in to see priceOverview
With the standard RDM (Remote Device Management) protocol, D4-F supports DMX512 signal bi-directional communication, achieves remote management of reading and writing DMX addresses (DMX master controller must recognize the RDM protocol). It realizes 0-100% dimming or different lighting effects. It can work with DIM, CT, RGB, RGBW LED lamps.

Test conditions and notes2
- When more than 32 DMX decoders are connected, DMX signal amplifiers are needed and signal amplification should not be more than 5 times continuously. If you need to modify the parameter settings of connected DMX/RDM decoders that exceed 32, you can add 1 RDM signal amplifier. Or you can add 1-5 DMX signal amplifiers after completing the parameter settings.
- If the recoil effect occurs because of long signal line or poor quality wires, please try to connect 0.25W 90-120Ω terminal resistor at the end of each signal line.

FAQ
What type of LED loads is the Ltech D4-F designed to control?
The Ltech D4-F is a constant voltage 4 channel DMX/RDM decoder for compatible LED lighting loads. It supports DIM, CT, RGB, and RGBW LED lamps, making it suitable for several common low-voltage lighting control scenarios.
Does the D4-F support RDM as well as standard DMX512 control?
Yes. This model supports both DMX512 and RDM, which allows bidirectional communication when the DMX master controller also recognizes the RDM protocol. That can simplify remote management tasks such as reading and writing DMX addresses.
What are the electrical ratings of the Ltech D4-F?
The D4-F operates on 12-24V DC input and is rated for 5A per channel across 4 channels, with a 20A maximum total load. Its listed output power is up to 120W per channel and 480W maximum overall, depending on the operating voltage and load conditions.
Is the D4-F a good fit for commercial or industrial environments?
It can be a strong fit for demanding environments because it is rated for operation from -30°C to 65°C. That wide working temperature range makes it more suitable for tougher conditions than many indoor-only control devices.
How does the D4-F compare with a basic non-RDM DMX decoder?
A key difference is that the D4-F supports RDM in addition to standard DMX512. Compared with a basic DMX-only decoder, this gives it added remote management capability for compatible systems while still providing four channels of constant voltage dimming control.
What protection features does the Ltech D4-F include?
The D4-F includes short circuit and overload protection with automatic recovery. That helps protect the decoder during fault conditions without requiring manual reset in the listed protection scenarios.
