DC-DC Constant Current Output LED Driver with DALI Dimming

August 15, 2017 by Paul Shepard

MEAN WELL has unveiled the new LDD-H-DA dc-dc LED driver series with DALI dimming function. The LDD-H-DA series is a constant-current step-down converter with a 6- to 50-Vdc input voltage range and 3- to 45-Vdc output voltage range.

Its output current range covers 350- to 1400-mA with DALI dimming function, which completely meets the needs of DALI intelligent control in lighting fixture system. Both pin style (LDD-H-DA) and wire style (LDD-H-WDA) are potted, reaching IP65 waterproof and dustproof.

In addition, pin-style LDD-H-DA model has built-in PWM and analog dimming function, remotely controlling power ON/OFF, and pwm function is able to further adjust output current.

LDD-H-DA can be deployed to the dc output side of constant voltage ac-dc LED driver, providing constant current to drive LED luminaries to stabilize current and extend fixtures lifespan. This product is utterly suitable for indoor and outdoor LED lighting system, such as street lighting, landscape lighting, tunnel lighting, household lighting, office lighting, and so on.

Additional features include:

  • Working efficiency up to 95%
  • Comply with EMI without any additional components (EN55015)
  • DALI dimming function
  • Built-in PWM dimming and remote ON/OFF control functions (pin style)
  • Fully encapsulated with IP65 level
  • Short circuit protection
  • Dimension (L x W x H) of 40.6 x 23.5 x 10.1 mm
  • 3-year warranty
