Frequently Asked Questions
What type of LED load is the Ltech M4-E designed to control?
The Ltech M4-E is a constant voltage 4-channel DMX/RDM decoder for low-voltage LED lighting systems. It accepts 12-48V input and provides PWM dimming control for constant-voltage applications rather than constant-current LED loads.
Does the M4-E support both DMX512 and RDM control?
Yes. This model supports DMX512 input along with RDM, which allows device parameters and DMX addressing to be viewed and adjusted through an RDM-capable controller. That makes it better suited for managed lighting systems than DMX-only decoders.
What are the voltage, current, and power limits of the M4-E?
The M4-E operates from 12V to 48V DC. It is rated for up to 8A per channel and 24A maximum total across 4 channels. Total output power is listed as up to 1152W at 48V, with lower maximum wattage at lower input voltages.
Can the M4-E be used in systems that need high-resolution dimming?
Yes. The decoder supports optional 16-bit grayscale control with 65,536 levels, as well as 8-bit control with 256 levels. This makes it suitable for applications where smoother dimming transitions or finer intensity control are important.
What makes the M4-E different from the M4-C version?
The main stated difference is the DMX interface type. The M4-E uses an RJ45 DMX signal port, while the M4-C version uses green terminal DMX interfaces. Buyers typically choose between them based on the interface format required by their control system.
Is the M4-E suitable for demanding commercial or architectural environments?
It is designed for professional control applications with protection against short circuit, over-temperature, and over-current conditions, plus auto recovery. Its working temperature range of -30°C to 55°C also supports use in a wide range of indoor or protected commercial environments.
What control and output options are available on this decoder?
The M4-E supports switchable DMX mode and customized mode, optional standard or smooth dimming behavior, and selectable 1, 2, 3, or 4 DMX channel output. It also offers a wide PWM frequency range from 300Hz up to 18000Hz, which can help match different lighting performance requirements.
