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.

Please Note:

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

Load Rating 1.8 kW 4
Please Note:

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 5
Please Note:

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.
