MEAN WELL LDD-350LW DC-DC Constant Current LED Driver 350mA 11W 9-36V Input

DC-DC constant current LED driver module from the LDD-L series, providing a stable 350 mA output current for LED lighting applications. It operates from a 9-36 VDC input and delivers up to 11 W of power with a maximum output voltage of 32 VDC. The step-down (buck) topology ensures efficient power conversion in a compact encapsulated module with through-hole mounting.

Advantages

PWM dimming control allows precise brightness adjustment. Built-in protection against short circuit, over voltage, and over temperature enhances reliability. Non-isolated design reduces cost and size for applications where isolation is not required.

Suitable for

• LED lighting systems requiring constant current drive
• Low-voltage DC input applications (9-36 VDC)
• Compact designs needing through-hole mounting
