15-20 Amp Dimmer Modules
Standard Dimmer Series
SPECIFICATIONS
DIMMER MODULES Dimmers are UL and cUL listed for continuous
duty at 100% of rated load
D15 – 1.8kW
D20 – 2.4kW
Dimmer modules are plug-in, and may be
replaced without tools
Cast aluminum chassis, finished with textured
epoxy paint
Includes circuit breaker(s), toroidal filter(s),
SCR modules, power and control connectors
Keyed to prevent insertion in
inappropriately rated rack positions
CIRCUIT BREAKERS Fully magnetic to eliminate nuisance tripping
20x inrush current rating
125%, 10-120 seconds, must- trip rating
Rated for 100% switching duty applications
SCR ASSEMBLY Sealed, patented assembly
Field replaceable with screwdriver
Two back-to-back SCRs per circuit
One Control LED per circuit
4000V isolation between control and
power components
Integral bonded heatsink
Integral temperature sensor
CHOKES High quality 350µS, risetime* toroidal filters
500µS risetime* filters in the Enhanced version
ELECTRICAL 100k AIC rating
RATINGS Hot-patching: dimmers shall withstand hot-
patching of cold incandescent loads up to the
dimmer's full rating, without tripping
Rated for continuous operation at full load
*Risetime measured at full load, at worst case firing angle
(about 50%), from 10-90% of output wave form
Maximum BTU Production per module
Model# BTUs Watts Efficiency
D15 380 112 96.9%
D20 522 154 96.8%
D15E 474 140 96.1%
D20E 810 238 95.0%
These values should be provided to a qualified HVAC design engineer, along
with dimmer quantities, types and dimmer room dimensions, to calculate
dimmer room air handling requirements.
Dimmer room HVAC systems must at all times maintain the specified ambient
temperature at the dimmer rack. Dimming systems operating within 10°F of
the upper or lower temperature limits must strictly follow installation and
operation guidelines to operate reliably.
