Mean Well NLDD-500H dimmable driver

Product details

Mean Well NLDD-500H dimmable driver is a DC to DC constant-current driver designed to power multiple ~3V LEDs (the exact number depends on your DC power supply and the LEDs you use). In an LED lighting build, it helps keep LED output current stable while allowing brightness control via dimming. It is typically selected when you need a dimmable driver solution that works with a specific input DC power source rather than an AC-input LED driver.

Features:

• DC to DC constant-current design for driving ~2–15 x 3V LEDs (number depends on your power supply and LEDs)
• Output voltage runs about 2–3V lower than the input voltage, helping match LED load requirements
• Requires a DC power supply (unlike Mean Well HLG or LPC families)
• Includes pins intended for easier installation on the LDD-H-4S board
• Supports PWM dimming down to 1% brightness for finer control

Specifications:

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