Mean Well HLG-40H-24B 40W 24V DC LED Driver with 3-in-1 Dimming IP67

The Mean Well HLG-40H-24B is a high-efficiency 40W LED driver with a constant voltage + constant current output of 24V DC and 1.67A. Designed for demanding indoor and outdoor applications, it features a wide input voltage range (90~305VAC / 127~431VDC), active PFC, and 3-in-1 dimming (0-10VDC, PWM, resistance). With an IP67 rating and rugged metal case, it ensures reliable performance in harsh environments.

Advantages

High efficiency up to 90% reduces energy loss and heat generation. The built-in active PFC (>0.95) meets harmonic current regulations. Multiple protection features (short circuit, overload, over voltage, over temperature) safeguard the driver and connected LEDs. The 3-in-1 dimming function offers flexible control options for various lighting systems.
