Mean Well NLDD-350H dimmable driver

Product details

Mean Well NLDD-350H dimmable driver is a DC-to-DC constant-current LED driver designed to power chains of low-voltage ~3V LEDs. It’s useful when you want to run multiple LEDs from a DC power supply while maintaining a more stable current for the LED string, and you also need PWM-based dimming for finer brightness control. This driver is intended to be paired with a compatible DC input source and LED arrangement, and it can be used in setups where you’re building or upgrading aquarium lighting that uses LED strings rather than plug-and-play AC drivers.

Features:

• DC-to-DC constant-current design for driving suitable LED strings
• Supports LED string configurations using multiple ~3V LEDs, depending on your power supply and LED setup
• Output voltage is always 2–3V less than the input voltage, helping with voltage headroom planning
• Requires a DC power supply (unlike Mean Well HLG or LPC driver families)
• PWM dimming supported, capable of dimming down to 1%
• Includes pins intended for easier installation on the LDD-H-4S board

Specifications:

• LED compatibility (guidance): For driving approximately 2–15 x 3V LEDs, depending on your power supply and LEDs
• Output voltage behavior: Output voltage is always 2–3V less than input voltage
• Input requirement: Requires a DC power supply
• Dimming method: PWM controller
• Minimum dimming level (PWM): Dimmable down to 1%
• Installation aid: Comes with pins for easier installation on the LDD-H-4S board
