Mean Well NLDD-1050H dimmable driver

Product details

Mean Well NLDD-1050H dimmable driver is a DC-to-DC constant-current LED driver designed for powering a small string of low-voltage LEDs (commonly around 3V class). In aquarium lighting setups, it’s typically used when you want a reliable current-controlled output for your LED array, while still being able to dim the lights using a PWM signal and an external DC power supply.

Features:

• DC to DC constant-current design for driving a series of low-voltage LEDs
• Supports an LED string of approximately 2 to 15 LEDs of about 3V each (the usable number depends on your specific DC input supply and LEDs)
• Output voltage stays about 2–3V lower than the input voltage, helping with stable series operation
• Requires a DC power supply (not an AC input) unlike some other Mean Well driver families such as HLG or LPC
• Dimmable down to 1% brightness using a PWM controller
• Includes pins intended for easier installation on the LDD-H-4S board

Specifications:

• Driver type: DC to DC constant current driver
• Compatible LED string (typical): ~2–15 x 3V LEDs (depends on your DC power supply and LEDs)
• Output vs. input voltage: Output voltage is always 2–3V less than input voltage
• Input requirement: Needs a DC power supply
• Dimming method and range: PWM dimming down to 1%
• Installation: Comes with pins for easier installation on the LDD-H-4S board
