ETC/Elec Theatre Controls D20DHR
Sensor3 Dual 20A Dimmer Module with Advanced Features and 800µS Rise Times


Hundreds of thousands of ETC Sensor modules are lighting up venues everywhere.  Professionals choose them because they are cost-effective and deliver maximum reliability with a minimum failure rate.  Known for technical elegance, Sensor3's highly integrated design means fewer parts for fewer failures.  And Sensor3's plug-in modularity allows for more configurability, customization and easy maintenance.

Sensor3 modules meet your system's unique needs, offering a wide variety of risetimes to customize to your noise requirements, and a wide variety of amperages to match your fixture inventory.  Advanced Features modules contain embedded voltage and current sensors.  These sensors constantly monitor circuit-status information, which is analyzed by the control electronics to diagnose and report circuit-specific load changes (individual lamp failures) or module faults.

You choose your power.  Sensor3's ThruPower module gives you a choice of local override or standard control for each circuit.  When the switch on the front of the module is in the On position, power is routed directly from the breaker to the output without passing through the dimmer or toroid filter (choke), which prevents the control system from turning off the output voltage – even if the control module is removed from the system.  While in the Dim position, CEM3 controls operation of the module as a relay or a dimmer.
