The ETC D50AF Dual 50 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.


Incandescent, Low voltage, Quartz, Neon, and Cold Cathode lighting
2-wire / 4-wire Fluorescent ballast
Voltage, current, and temperature sensors in each dimmer
D15AF and D20AF modules are dual density/D50AF modules are single density/D100AF modules are half density
Dual back-to-back SCRs for each circuit
High-density modular plug-in assembly
Die-cast aluminum chassis
Fully magnetic circuit breakers to eliminate nuisance tripping


Modular plug-in assemblies
Cast aluminum chassis, finished with textured epoxy paint.
Keyed to prevent insertion in inappropriately rated rack positions

Power Device

Field replaceable with screwdriver

    Circuit Breaker Inrush Current Rating: 20x
    Must-Trip Rating: 125 %, 10 to 120 seconds

    Rated for 100% switching duty applications

    Compatibility Installation racks: Sensor3, Sensor+, and SR Touring Racks: Sensor+ 24 module Touring Rack & Sensor+ 48 module Touring Rack Portable Packs: Sensor3 & Sensor+

    Rack enclosures also available for 230 CE and 240 V applications

    Rise Time 6 kW

    Rise time measured at full load, at worst case firing angle (90°), from 10-90% of output wave form

    Load Rating 1.8 kW

    UL and cUL Listed for continuous duty at 100% of rated load

    SCCR Rating Single Cycle Peak Surge Current: 625 A
    Half Cycle Peak Surge Current: 1620 A
    Transient Over Voltage: 600 V
    Dimming Range 100 to 0%, Incandescent

    Dimming range of 2 & 4-wire fluorescent ballast depends on lamp ballast combination.Sizing of neon transformer for dimming application should be 1.5x greater than size of non-dimming application.

    BTU Production BTUs: 808
    237 W
    Efficiency: 96.1%, Maximum

    Dimmer room HVAC systems must maintain ambient temperature of dimmer rack. Dimming systems operating within 10°F of upper/lower temperature limits must follow installation & operation guidelines
