The LED driver LW04-Mod includes four programmable constant current outputs with a maximum output of 25
watts per output. Each output can independently supply a constant current between 80mA and 1A.
The brightness of each channel is controlled by each an internal 12 bit PWM signal. The brightness of the outputs are
therefore independently. This module controls your lights next to external control via DALI or DMX 512 also
functions as an autonomous independent scene control.
By DALI, DMX-512 and I2C LED driver is controlled directly.
A special feature: If the LW04-Mod is programmed via I2C he works without external control!
The independent (autonomous) operation allows light scenes, sequences, color sequences.
Flickerfree/Camera suitable: To avoid fllickering from LED-luminaires, the Spread-Spectrum-Technology is integrated into the LW04-module. Thereby the pwm-frequency is constantly altered with a pseudo randomizer, which prevents interferences due to other light sources and makes the flicker invisible for cameras. The generated frequencies go up to 184kHz, which is absolutely unrecognizable for the human eyes.
With the programmable output currents it is possible to operate with different LEDs and only one driver.
