Mean Well NLDD-700H dimmable driver

Product details

Mean Well NLDD-700H dimmable driver is a DC-to-DC constant current LED driver designed to power multiple 3V-class LEDs in series/strings, using an external DC power supply. In aquarium LED builds, it’s typically used when you want stable LED current and the ability to dim the lights using a PWM controller. Its practical advantage is that it provides a predictable LED drive mode while allowing brightness control without switching the LED circuit itself.

Features:

• DC to DC constant current design for powering LEDs reliably
• Supports driving approximately 2–15 x 3V LEDs depending on your LED setup and power source
• Output voltage runs 2–3V lower than the input voltage
• Requires a DC power supply (unlike Mean Well HLG or LPC driver families)
• Includes pins intended to simplify installation on the LDD-H-4S board
• Dimmable down to 1% using a PWM controller

Specifications:

• Driver type: DC to DC constant current LED driver
• LED compatibility (guidance): For driving about 2–15 x 3V LEDs (system-dependent)
• Output vs input voltage: Output voltage is always 2–3V less than input voltage
• Power requirement: Requires an external DC power supply
• Dimming: PWM dimming down to 1%
