  • DIN rail mounted dimming driver for constant current LEDs.

  • Smooth, flicker-free dimming from maximum current set to 0.0001%.

  • Multi load’s proprietary Constant Current Reduction (CCR) technology keeps RFI along cabling to a minimum (current is not constantly switched on/off as in PWM dimming).

  • Can be positioned over 100m from the LED light source(s), allowing placement in electrical distribution cupboards or other convenient locations. This eliminates the need for drivers to be placed in the ceiling, making maintenance easier, eliminating ceiling clutter and allowing DC voltages to be used in installation –greatly reducing electrical noise.

  • Dimming via 0/1-10V input control signal.

  • DALI and DMX interfaces available.

  • Hot pluggable – allowing LEDs to be replaced without switching off power to the LDR100.

  • Short circuit protected.

  • On-board monitoring of current settings over time, allowing warranties to be honoured.
