Does the LT-820-5A support DMX only, or does it also support RDM?
This model supports both DMX and RDM dimming control. That makes it a fit for projects that need standard DMX operation while also using RDM-compatible control environments.
What are the main electrical ratings of the LT-820-5A?
The LT-820-5A supports an input voltage range of 5 to 24 Vdc. It provides a maximum total load current of 20 A and a maximum output power of 480 W, distributed across 4 channels.
Does this decoder offer fine dimming control for professional lighting applications?
The LT-820-5A supports a dimming range of 0 to 100%. This allows for smooth control of connected constant-voltage LED loads within the specified power and current limits.
Can the DMX address be viewed directly on the unit?
The LT-820-5A features a digital screen that allows you to set and read the DMX start address. This simplifies addressing management on larger DMX lighting systems.
Is the LT-820-5A suitable for demanding indoor or industrial environments?
This model is rated for operation from -30 degrees C to 55 degrees C, which supports use in a wide range of environmental conditions. Buyers should still confirm that the surrounding enclosure and full system design match the needs of the application.
What warranty is provided for the Ltech LT-820-5A?
The listed warranty period for this model is 5 years. That longer warranty term can be a meaningful consideration for commercial buyers comparing controller options for ongoing projects.
