FAQ
What does the Ltech D4A do?
The Ltech D4A is a constant voltage DMX/RDM decoder for LED control systems. It provides 4-channel output and is designed for dimming and control of compatible constant voltage LED lighting loads.
Is the D4A compatible with both DMX512 and RDM systems?
Yes. The D4A supports standard DMX512 input and also supports RDM, which allows parameter browsing and DMX address changes through an RDM master.
What voltage and output capacity does the D4A support?
The D4A is designed for 12-48V constant voltage systems. Its maximum total output current is 24A, with rated output listed as 8A x 3 channels or 6A x 4 channels. Output power is rated up to 288W at 12V, 576W at 24V, 864W at 36V, and 1152W at 48V.
What dimming and performance options are available on this model?
The D4A supports 0-100% dimming range. It is designed for constant voltage LED loads with DMX512 and RDM control protocols.
What kinds of LED control applications is the D4A suited for?
This model is suited for multi-channel constant voltage LED control where DMX or RDM integration is required. Its 4-channel output makes it useful for architectural, display, and commercial lighting projects. It is positioned as a control component for professional LED systems.
What is the difference between the D4A and D4B versions?
The D4A uses a green terminal DMX interface. The distinction given here is the DMX signal port style rather than a change in output class or control protocol. If port format matters for your system standard, that is the key comparison point between these two versions.
Is the D4A suitable for demanding operating environments?
The listed working temperature range is -25°C to 55°C, which supports use in a wide range of indoor or protected commercial environments. The unit also includes short circuit, over-temperature, and over-current protection with auto recovery. It carries CE and FCC Part 15 Class B compliance information.
What warranty is listed for the Ltech D4A?
The D4A is a professional LED control component suitable for commercial applications. Buyers should confirm any seller-specific warranty terms at the time of purchase.
