You can find our 90% DMX512 led tapes are the UCS512 version, especially for the DMX512 RGBW LED tapes are the UCS512C4 series.
This UCS512 C4 IC chip protocol, also known as DMX512 IC, was designed by UCS New Technology Co. in China. It uses a standard DMX512 differential protocol to drive IC pixel chips.in another words, we can say TTL 485 protocol.
UCS512C4 offers all the same features as its RGB version, UCS512C3, but it is 4 channels output which is dedicated to RGBW design. It comes in a SOP16 package.
UCS512C4 Technical Specifications:
| Data Type | A,B signal |
| Color Resolution | 8 bits |
| IC package | SOP16 |
| RGB | Yes |
| RGBW | Yes |
| Output Voltage | 5-24V |
| Output Current | 3-60mA/Channel |
| PWM Rate | 3.6KHZ |
| Refresh Rate | up to 120 fps |
| Data transfer Speed | 200-750kbps |
UCS512C4 Advantages:
- Very High PWM rate 3.6KHZ allows for filming the pixels with around 120fps appromately.
- External output constant current adjustable resistor, current range 3~60mA per channel to choose.
- Presence of white LED allows for be independently controlled to create bolder and more vibrant colors than with RGB alone.
- When write DMX512 address via the DMX512 address writer, no need to connect the address cable.
- Maximum distance to write DMX address code is no relationship with the PI cable distance.
- The UCS512C4 has a PWM reverse polarity frequency reduction output, allowing for external high current driver devices.
UCS512C4 Shortcomings:
- 8 bits of color resolution, 256 grayscale for each color makes dimming curves less smooth.
- Couldn't wirte DMX512 address automatically.
UCS512C4 applications:
- DMX512 RGBW Pixel LED tapes from 5V - 24V that leds denstity from 32 leds - 120 leds.
- DMX512 LED pixel point lights, wall washer lights.
- Stage lighting systems, video walls.
