This constant current source modul (CCS-Modul) CCS2-600-HV48 able to supply with 600mA constant current one LED or several in series connected LEDs. Depending on application output current can be regulated by DIM input. The modul was developed special for space and reliability critical application. Integrated input and output filters allow interference free operation and at the same time reduce current and voltage ripple at LED. High effeciency and as result sligth temperature rise allows operation without heatsink.
