Frequently Asked Questions

What kind of LED loads is the Ltech D4B designed for?

The Ltech D4B is a constant voltage DMX/RDM decoder for low-voltage LED lighting systems. It supports 12-48V constant voltage output, so it is intended for compatible constant voltage LED applications rather than constant current fixtures.

How many channels does the D4B support?

This model supports up to 4 output channels. It can also be configured for 1, 2, 3, or 4 DMX channel output depending on the control mode required by the lighting system.

Does the D4B support both DMX512 and RDM?

Yes. The D4B supports standard DMX512 control and RDM functionality, allowing parameter browsing and DMX address changes through an RDM master or the supported mobile app workflow mentioned by the manufacturer.

What is the maximum output capacity of the Ltech D4B?

The D4B is rated for a maximum total output current of 24A. Its published output power is 288W at 12V, 576W at 24V, 864W at 36V, and 1152W at 48V.

What dimming and control resolution options are available on the D4B?

This decoder offers 0-100% dimming and supports either 16-bit gray scale with 65,536 levels or 8-bit gray scale with 256 levels. It also provides standard and smooth dimming modes, along with multiple PWM frequency options up to 18,000Hz.

Is the Ltech D4B suitable for demanding commercial environments?

The D4B is built for commercial LED control applications with an operating temperature range of -25°C to 55°C. It also includes short circuit, over-temperature, and over-current protection with auto recovery, which supports reliable use in tougher environments.

What interface does the D4B use for DMX signal input?

This model uses an RJ45 DMX signal port. That is a distinguishing feature noted for the D4B version in the product specifications.

What certifications and compliance standards are listed for the D4B?

The product listing shows CE compliance and FCC Part 15 Class B. It also lists EMC-related standards including EN 55015, EN IEC 61000-3-2, EN 61000-3-3, and EN 61547-1.
