LNX-280DVL constant voltage 8-channel DMX decoder overview

Flexible Port Aggregation Solution

The LNX-280DVL features 8 PWM drive ports for constant voltage LED fixtures, each equipped with 5 terminals: V+/R/G/B/W. The white (W) channel can be configured for different operating modes via RDM, meeting diverse LED control requirements.

  • 8 independent constant voltage PWM drive ports, supports RGB/RGBW LED strips
  • PWM refresh rate up to 55KHz for flicker-free, perfect visual performance
  • 1-8 ports freely aggregatable to suit different power requirements
  • RDM remote device management for efficient centralized control
  • DMX isolated ports for stable and reliable signal transmission
  • DIN rail mounting for space-saving centralized installation

Key Features

Technical advantages of the LNX-280DVL

Wide Voltage Range • Smart Protection

The LNX-280DVL provides a wide operating voltage range of 5-48V. Each dimming channel supports up to 4A, each port (RGBW) delivers up to 16A combined, and the total unit current reaches 128A. The decoder works with 12V / 24V / 48V constant voltage LED strips or fixtures, featuring internal reverse polarity protection and inrush current protection for safe and reliable operation.

Through RDM configuration, port aggregation modes can be set remotely: 2-port, 4-port, or 8-port aggregation, enabling higher-power dimming or special installation scenarios from a single DMX channel.

DIN Rail Mounting • Easy Maintenance

The standard DIN rail design is ideal for centralized installation in control cabinets. Whether for commercial lighting, landscape illumination, or stage lighting projects, the LNX-280DVL provides a stable and reliable decoding and driving solution, significantly reducing installation and maintenance costs.

  • 5-48V ultra-wide voltage input, compatible with various LED fixtures
  • 4A per channel / 16A per port / 128A total unit drive capacity
  • Flexible port aggregation for high-power applications
  • Dual circuit protection: reverse polarity and inrush current
