LEDs at 400 mA each simultaneously or one LED at
800 mA. Low dropout PowerLite ? Current Regulator
(PCR) increases device’s efficiency up to 90%.
The EN logic input functions as a chip enable.
The LEDs current is programmed at 400 mA for both
channels in the factory. Please, consult factory about
other current values. Each LED current can be
programmed separately in the factory from 52 to
800 mA in 25 mA steps for LEDA and in the range
