The Mean Well LDB-500LW is a constant current DC-DC LED driver with both a wide input and output voltage range. The buck-boost feature of this driver allows a higher output voltage than the input voltage. This is particularly desirable when dealing with a 12V or 24V supply often found in vehicles and marine vessels.
