This Daisy Chain Power Cord is specially designed for the new Model-One System to interconnect between the LED drivers. The Model One system can reduce the number of power outlets and cables required by combining multiple LED drivers together into a single power cable. Each “group” of Model One drivers must be connected to power using one of the TDC-1 cables, and one of the EC-120 or EC-240 power cables (120 or 240 volt). The TDC-1 power cord is used to connect to the main power source and to transfer data from the HCS lighting controller to the LED drivers.. The TDC-2/3/4 are used to connect the power and the control signal from one LED driver, to the next LED driver.
