The ETC D20AF Dual 20 A Dimmer Module (500 μS) is designed for use in Sensor+ dimming series modular rack enclosures. The module enables dimmer-specific feedback of load circuit data while performing digital phase angle dimming in AF-capable Sensor+ dimmer enclosures. The high-density, dimmer modules feature modular installation and removal, fully magnetic circuit breakers, and enhanced rise time toroidal filters.
