Saelig Company Inc. (Fairport, NY) has announced the LED-Warrior04, a 4 channel, intelligent, programmable LED constant-current driver with DALI, DMX512, and I2C interfaces on board. Other bus protocols or wireless options can be added via the I2C interface. For each of the four channels, the forward current and brightness of the LEDs can be individually and independently programmed. Current can be programmed from 80 mA to 1000 mA in 5mA steps. Brightness is controlled by internal 12-bit PWMs for each channel, allowing 4096 steps, with dimming down to 1/4096 or 0.024%. The high resolution of brightness control allows precise color mixing or calibration of multiple LED groups. The four 12-bit channels allow up to 281 trillion color hues.
