Specifications
n
Dimmer modules shall be fully plug-in
and factory wired. Dimmer modules shall
consist of a heavy duty chassis with inte-
gral top, bottom, side and face panels.
No tools shall be required for module
removal and insertion.
n
Up to ten remote control key switch
stations shall be available.
n
The removal of any single module shall
not expose line or low voltage termina-
tions less than six (6) inches from the
front of the rack.
n
Each module shall be labeled with the
manufacturer's name, catalog number
and rating. Modules constructed of
molded plastic for structural support are
not equivalent and are not acceptable.
Dimmer modules shall be UL, c-UL
Recognized.
n
Dimmer modules shall be available as
dual 1.2kW, dual 1.8kW, dual 2.4kW or
single 6kW. Dimmer modules shall be
available to accommodate incandescent,
low voltage, and non-incandescent
loads.
n
Each dimmer shall provide, but not be
limited to, the following:
A. The dimmer module shall contain a circuit
breaker for each circuit, a solid state
switching module, associated toroidal
filters, status indicator, and power and
control connectors.
B. The dimmer module shall not have
any protruding connector pins subject
to physical damage when the module is
not installed.
C. Circuit breakers shall be fully magnetic
and UL listed. The trip current shall not
be affected by ambient temperature
within the operational specifications of
the system.
n
Each dimmer module shall use a solid
state module (SSM) consisting of two
silicon-controlled rectifiers (SCRs) in
an inverse parallel configuration and
all required gating circuitry on the high
voltage side of an integral, opto-coupled
control voltage isolator. The SSM shall
be thermally protected, independent of
the control module. SSM shall provide
minimum of 10,000V RMS isolation
between the line and control sides of
the device.
n
All Rise-Time measurements are between
10%-90% with dimmer output at 50%.
Alternate manufacturers must supply
either high performance chokes or certi-
fied test data ensuring compliance with
the above.
n
The standard dimmer (350 μS) shall
have an insertion voltage drop of no more
than 3.4 volts rms at the maximum
rated load with 120 volts input. The high
performance dimmer (500 μS) shall have
an insertion voltage drop of no more than
5.5 volts rms at the maximum rated load
with 120 volts input. The ultra perform
ance dimmer (800 μS) shall have an
insertion voltage drop of no more than
7.9 volts rms at the maximum rated load
with 120 volts input. The maximum heat
loss for each 2.4kW dimmer shall be no
greater than 100 BTU per hour per con
nected kilowatt of load.
