LED lighting is booming! Especially for LED strings and multi-chip arrays, the advance is enormous. The required input voltage for buck-drivers increases with the number of LEDs which have to be supplied with constant current. Currently available models had a limit of approximately 40V.   Not so with RECOM’s new RCD-48-family. With input voltage up to 60VDC and constant current outputs of 350, 500, 700 and 1200mA offering device power rating up to 70W. This corresponds to 350W of conventional lighting power! The new buck-driver is ideal for operati...
