Many modern light fittings dim by ELV. Yet many existing lighting installations are 0-10v! This new Bridge device converts a 0-10v signal into an ELV signal and solves this problem. It dims incredibly smoothly without any flicker even at the low end. Another great feature is that it can be addressed by DMX 512 and be controlled remotely and individually using a DMX controller. 100-277v. 2000w. IP67 so it can be installed outside. Enjoy!
