Description

Mean Well's LDB-L Series DC-DC LED drivers offer constant current buck-boost mode output. This low voltage driver features 9-36VDC input and outputs 2-40VDC. The buck-boost mode allows for slightly higher or lower LED voltage than your input voltage. They have a built-in EMI filter that complies with EMI lighting requirements (EN55015) without connecting any EMI restraint components, making them very convenient for PCB installations. Another great feature is they can be dimmed via PWM dimming controls. 

Connection Style Variations

The Mean Well LDB-L series comes in 2 different connection types. The standard is a pin version, and 'W' is the wired version.
