Product
Overview
Features
Tunes maximum light level
output for greater energy
savings potential
Dimming convenience
with 0-10V ballasts
• Single package with relay outputs, dimming
channels, power supply, and device inputs for
simpler installation
• Two switch inputs accept three-wire momen-
tary, two-wire momentary pushbutton, or
maintained low voltage switches
• Hold-ON feature keeps lighting on during
scheduled time, reverts to occupancy sensor
control after hours
• Burn in timer prevents lamps from dimming for
initial 100 hours for extended lamp life
The LC-100 is a power pack with two relay outputs
and two dimming channels delivering both switch-
ing and 0-10V dimming control to lighting loads.
Signal inputs offer integrated operation with a
range of control devices.
Dimming Control
Applications
The LC-100 integrates control of other devices
to meet room-specific lighting control needs. It
is ideal for compliance with bi-level switching,
daylighting and lighting shutoff energy code provi-
sions. Where load shedding is needed, the LC-100
can switch off non-critical lighting while leaving
other lighting on. Or with controllable ballasts, it
can dim lighting down to preset load “shed” levels.
Operation
A dual voltage device capable of operating at either
120 or 277V, the LC-100 installs as a standard
power pack, connecting to junction boxes in a
ceiling or a location close to controlled loads. With
24VDC at 150mA available, it provides power to
occupancy sensors, photocells, and other devices.
Low voltage switch inputs give occupants ON/
OFF switching and up/down dimming control of
two independent lighting loads. Separate signal-
ing inputs for occupancy sensors, time clocks and
photocells allow shutoff and daylighting control
while providing convenient scenarios (i.e., blink
warning, manual on or auto on, hold on, on only) to
meet control needs.
Description
• Pilot light output for status annunciation at
switches
• Blink warning five minutes prior to shutoff
• Isolated relay contact for each relay output pro-
vides status
• Manual ON/Auto ON settings for convenience
and energy savings
• After hour override adjustable to 30 minutes, 1
hour, 2 hours or 4 hours
• Works with the LS-301 dimming photosensor to
provide closed loop dimming control
• Qualifies for ARRA-funded public works projects
When used with 0-10V controllable ballasts, the
LC-100 provides dimming and ON/OFF control
of up to 100 ballasts per dimming channel.
Occupants can conveniently dim up/down and turn
lighting ON/OFF using momentary low voltage
switches. The load shed feature dims lighting
to preset levels during peak demand periods to
reduce energy consumption. Lighting maximum
levels can also be set for greater energy savings.
