Ltech LT-904 Constant Voltage Decoder - DMX/RDM

The LT-904 is a constant voltage DMX/RDM decoder designed to control LED lighting loads from a DMX-based control system. This model provides 4 output channels and is intended for applications that need DMX signal decoding with remote device management support.

This model is rated for up to 576W total output power at 24V DC. It supports up to 6A per channel, with a listed rated current of 24A overall across its 4 channels.

Yes. The LT-904 supports DMX control and also includes RDM functionality, which allows compatible master consoles to browse parameters, set addresses, and identify the device remotely. That makes it better suited to managed lighting systems than a decoder that only handles standard DMX.

According to the product description, the LT-904 supports two DMX port formats: 3-pin XLR and RJ45. That gives buyers flexibility when matching the decoder to existing DMX infrastructure or control hardware.

It can be a strong fit for commercial and architectural LED systems that use DMX control and require a constant voltage decoder. The combination of 4-channel output, 24V operation, RDM support, and 576W maximum output makes it relevant for more capable multi-channel lighting control applications.

The listed operating temperature range is -30°C to 65°C. That wide range makes it suitable for demanding environments, provided the rest of the system is specified for similar conditions.

The main differentiator in the provided specs is RDM support, which adds remote management functions beyond standard DMX signal decoding. This model also combines 4-channel output, up to 6A per channel, dual DMX port types, and built-in short circuit and over-current protection.

The product description states that the LT-904 includes short circuit protection, over-current protection, and a warning function when a fault occurs. The listed warranty period for this model is 5 years.
