LED DALI Dimming Module
Overview
LED DALI Dimming Module (LDM) is a dimming module connected to the DALI communication line. This device controls ON/OFF and dimming of LED lighting, and supports up to 64 devices connected to a DALI master through the DALI protocol, enabling more advanced integrated control. The LDM series is classified into several types depending on the output configuration.
Feature
  • DALI protocol interface
  • Light dimming levels: 254 steps
  • 116 scenes and group settings
  • DALI standard: IEC 62386
  • Communication speed: 1,200 bps
  • Data: individual ON/OFF control, individual dimming control, lamp status/alarm signal, ballast status/alarm signal
  • Dimming range: 1% ~ 100%
  • Dimming time: programmable
  • No need for separate shielded communication cable; installation possible with general wiring
  • Uses 5C cable (3C-L/N/E, 2C-DALI) without separate communication line installation
  • No polarity required for communication line
  • Output types: Normal type connects directly to LED fixtures; PWM and 0-10V signal type for SMPS (LED driver)
Operation
Application
  • Applicable to various LED fixtures such as panel lights, downlights, and LED bars with DALI control
  • Compatible with all DALI controllers (master) using IEC 62386 standard
  • LED drivers must be constant voltage type, max 60V/3A and under 180W
  • LDM is installed near the driver on the back of the LED fixture using screws or magnets
  • Pay attention to polarity when wiring input/output voltage
  • LDM-2 supports up to 64 devices per DALI master for individual/group/scene control
  • Supports 16 groups
  • Supports 16 scenes
  • Fade time configurable
  • Fade rate configurable
  • Min/Max level configurable
  • Control via occupancy sensor
  • Control via light sensor
