The 8030 range of dimming LED Power controllers represents true innovation in LED technology. Excellent dimming (0-100%) is achieved via an on board DMX512 interface combined with 8 bid PWM power control, 256 steps brightness led control for every channel without flickering! Stand alone operation is also possible (build in colour changing combinations and test functions activated by DIP switch).
