About Power Through Modules...

The new Power Through EC21 Dimming/Switching modules represent the new options for future proofing your new or existing dimming systems.

These new Power Through modules offer a choice of dual 250uS or 400uS  rise time module (Silicon Controlled Rectifier) dimmer at both 16A  and 25A that combine a mechanical bypass relay in each dimmer.  They are also available with or without a reporting option.   Each module is equipped with two switches, one for each of the dimmer circuits in the module.   On the Power Thru Bypass module this two position switch allows the manual selection of either Dimmer or  ByPass mode to your circuit, while the Power Thru Relay moduleprovides a three position switch for selection of either Dimmer, ByPass or Relay control.
