Models and Capacities
Description
• Provides capability for a zone on a GRAFIK Eye
3000 Series Control Unit to control a larger
load. Allows the zone to dim or switch a fully-
loaded circuit of lighting.
• Dims or switches most popular lighting sources
and load types.
• Models available for 120 V , 220-240 V
(non-CE), 230 V (CE), or 100 V input
power.
Works with:
• GRAFIK Eye 3000 Series Control Units
• LP Dimming Panels
• HomeWorks Remote Power Panels
• Neutral-referenced wallbox dimmers by Lutron.
Two Power Boosters may be used on a zone to
double the capacity. Use the HP Dimming Module
System for zones that exceed the capacity of the
Power Booster.

Measured current will not exceed continuous load rating due to voltage drop in the dimmer.

Power
• Input power: 120 V , 220-240 V (non-CE),
230 V (CE), or 100 V . All voltages 50/60
Hz, phase-to-neutral.
• Load (output) power: Phase independent of
Control Unit.
Sources/Load Types
Operates these sources with a smooth continuous
Square Law dimming curve or on a full conduction
non-dim basis:
• Incandescent (Tungsten)
Halogen
• Magnetic Low-Voltage Transformer
1
• Lutron Tu-WireTM Electronic Fluorescent Dimming
Ballast
• Neon/Cold Cathode
Key Design Features
Patented RTISS
TM circuitry compensates in real
time for incoming line voltage variations: No visible
flicker with +/-2% change in RMS voltage/cycle
and +/-2% Hz change in frequency/second.
Terminals
Accept up to two #12 AWG (2.5 mm
2
).
Environment
32 °F - 104 °F (0 °C - 40 °C). Relative humidity
less than 90% non-condensing.
Mounting
Surface or recess mount indoors only.
Specifications

2-Gang
U.S. Wallbox
• Recess or surface mount in 2-gang U.S.
wallbox 3.5 in. (89 mm) deep. Indoors only.
• Power Booster generates heat; mount only
where ambient temperature is 32 °F-104 °F
(0 °C-40 °C).
• Mount with arrows facing up to ensure
adequate cooling.
• Allow 4.5 in. (114 mm) above and below unit
and between faceplates when mounting
several in a vertical layout.
• For better heat dissipation, surface mount
without faceplate.
• Mount so line (mains) voltage wiring is at
least 6 feet (1.8 m) from sound or electronic
equipment and wiring.
• Mount Interface within 7° of true vertical.

for input power and load circuit.
• Strip 1/2 in. (12 mm) insulation from wires before connecting.
• Run separate neutral for load circuit - no common neutrals.
Neutral (N) terminal is for Control Unit, not the load neutral.
The Power Booster may be on the same circuit
as the Control Unit only if the total load does
not exceed the rating of the breaker.
