Ltech LT-123 DMX(485) Signal Amplifier
Log in to see priceOverview
LT-123 is dedicated to amplify, distribute, and insulate the signal that comes from the lighting system equipment when it is connected to the bus of DMX512 (or RS-485).
Features
- 1. It's specially designed for signal shaping amplification for DMX512 (485) signal which attenuated after a long-distance transmission, realize extending the signal transmission distance;
- 2. Need to use the multiple signals expansion output control, increase DMX (485) signal amplifier to distribute multi-channel control.
- 3. 1 channel input, 3 channels distributed output, there is a independently photoelectricity insulation of >3KV between input and output terminals, and output terminals among 3 channels, so as to avoid the expensive equipment such as light, 485 communications equipment, DMX driver, precise digital lighting controller, being burnt by the possible high voltage which caused from the wrong wire connection and a broken equipment, also can avoid the signal interference between each DMX equipment, to assure it works safely.

FAQ
What does the Ltech LT-123 DMX(485) Signal Amplifier do?
The LT-123 is designed to amplify, distribute, and insulate DMX512 (RS-485) control signals in lighting systems. It helps maintain signal integrity after long-distance transmission and supports multi-channel signal distribution for more reliable control.
How many DMX signal paths does the LT-123 support?
This model provides 1 channel input and 3 distributed output channels. It is intended for applications where one DMX(485) signal needs to be expanded into multiple isolated output paths.
What kind of isolation does the LT-123 provide?
The LT-123 features independent photoelectric isolation greater than 3KV between the input and output, as well as among the three output channels. This helps reduce signal interference and adds protection for connected lighting and control equipment.
Is the LT-123 a dimming controller?
No, the LT-123 is not a dimming controller. Its role is signal amplification, distribution, and isolation for DMX512 (485) systems rather than direct dimming control.
Is the LT-123 suitable for demanding commercial environments?
It is suited for professional lighting and control applications that need stable DMX(485) signal distribution and protection against interference. The unit is rated for operation from -30°C to 65°C, which supports use in demanding environments.
