DALI2 Pushbutton Coupler

4 Channel

DMX2PWM Dimmers enable control of low-voltage LEDs using a DMX512 controller. Using PWM (Pulse-Width Modulation) technique, they are designed for use with constant voltage LEDs with a maximum output current of 2 A per channel, or 2.5 A for the three-channel version. DMX512 signal is amplified through DMX2PWM Dimmers for convenient daisy-chaining. DMX2PWM Dimmers’ flexibility makes installations easy with auto and manual DMX512 addressing modes, and in the case of the nine-channel version, the option of using an RJ45 connector or loose wire for DMX512 connection. The reverse supply protection and self-resetting over-current protection ensure safety against possible damage due to incorrect wiring. The nine-channel version is conveniently mountable inside equipment racks using standard 35 mm wide DIN rail.
