LT-123 DMX Signal Amplifier
1. Product Parameter:
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).
3.
2. Need to use the multiple signals expansion output control, increase DMX (485) signal amplifier to distribute
multi-channel control.
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;
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.
DMX (485) signal amplifier can isolate, amplify and distribute the signal to all kinds of DMX (485) control
equipment, see the example for the DMX Lighting.
