Mean Well LDD Series LED Drivers

Mean Well 's LDD Series DC-DC Converters were designed for LED applications. The Buck converters offer constant current mode output. They feature 9~36VDC input and 2~32VDC output( LDD-L) or 9~56VDC input and 2~52VDC output (LDD-H). A wide range of output current options are available, from 300mA to 1A. The LDD DC-DC Converters from Mean Well have an extremely high efficiency level of 97%. They have a built-in EMI filter and comply with the EMI lighting requirements of EN55015.
