The LDB75 series of constant voltage/current LED power supplies can
deliver up to 75W output power in an extremely compact package size.
The LDB75 can deliver constant voltage/current 24V, 36V and 48V outputs in a
compact package. At only 28.5mm high, the LDB75 offers the lowest profile LED
driver solution. Furthermore, the LDB75 can operate as a constant current driver
delivering the maximum output current range over the defined voltage range.
