Description

Mean Well's LDD-L Series DC-DC LED drivers offer constant current mode output. The LED buck converters feature 6-36VDC input and output 2-32VDC. These low voltage drivers come in a wide range of output drive current options: 300mA to 1 Amp. The MeanWell LDD DC-DC converters have a high efficiency of 97% allowing them to operate between -40°C~+85ºC. 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 +analog controls.

Connection Style Variations

The Mean Well LDD-L series comes in 3 different connection types. The standard is a pin version, 'W' is the wired version and 'S' is the SMD version where the pins are on the sides.

Product Support
