ALD Dimmer Modules
ALD Dimmer Modules are designed to dim electrical branch
lighting circuits as specified by electrical codes.
ALD Dimmer Modules are constructed so that the electrical
distribution for branch circuits is done directly by the dimmer
panel/module combination. No additional diistribution panel
is required.
Each dimmer module is constructed with input and output
circuit breakers. The main feed for the panel (typically a 3
phase/4 wire supply) is bussed to the input circuit breakers of
the dimmer modules. These breakers supply and protect the
dimmer. The output of the dimmer is connected to the
output circuit breakers which supply and protect the load.
Each lighting load can be connected to a separate dimmer or
several lighting circuits can be connected to one large
common dimmer.
The control of the ALD Dimmer is done with a control line
from the dimmer control electronics. (Control electronics are
not shown in the diagram.)
ALD Dimmer Modules rack mount into ALD dimmer
enclosures. The ALD-6 Panel can house up to 6 modules
and the ALD-12 Module can house up to 12 modules. The
cover of the ALD Panels permits convenient access to the
input and output breaker handles.
UL Listed (File #E107476)
CSA (Canadian Standards File #LR39552-13)
Modular, panel mount design to suit ADL enclosures.
Size range includes 1.2 kw, 2.4 kw and 6.0 kw dimmers.
Capability of multiple output breakers to service several
similar loads.
High-performance SCR technology with toroidal filtering to
ensure reliable, smooth dimming.
Suitability for all types of incandescent loads, including low-
voltage halogen (MR-16), quartz, neon and cold cathode
lamps.
Smooth dimming of incandescent loads from 0% to 100%.
The dimmers deliver a modified IES curve that is slightly
flattened at the low end to provide an expanded dimming
range for low light levels.
