RDA-CKM Dual Choke Module

The RDA-CKM Dual Choke Module is used for debuzzing, lamp noise
reduction, and to correct minor common neutral interactions. This unit con­sists of dual 350 µS rise time chokes. It occupies only one enclosure space
and is useful with the RDD-DM series of integrated dimmer modules. The
module's 120 and 240-277 VAC ratings are UL and C-UL approved.
