Tu-Wire control
Tu-Wire ballasts offer high performance 100% to 5% dimming for linear and compact fluorescent
lamps. Retrofit applications can benefit from the ease of installation offered by Lutron
® Tu-Wire
dimming ballasts. Tu-Wire ballasts require only two wires (dimmed hot and neutral) for power and
control. Lutron offers a wide range of compatible Tu-Wire controls, making Tu-Wire ballasts a perfect
choice for many applications. Additionally, one-lamp T4 models have been designed to meet FCC Part
18 consumer requirements for residential applications.
High performance dimming to 5%
Tu-Wire controlled
Mounting
•
Ballast mounts using two mounting tabs or studs
within a fluorescent fixture
•
Lutron and NEMA® recommend sockets complying
with IEC 60400. Sockets must have a UL mark
as well. Use rapid start sockets, not instant
startsockets.
•
Terminals accept 16-18 AWG (0.75 to 1.5 mm
2
)
solid copper or tinned stranded wire
Wiring
•
Tu-Wire ballasts require 2 wires plus Ground
(Dimmed Hot and Neutral); one 16-18 AWG solid
copper Class 1 wire per terminal
•
Maximum ballast-to-lamp-socket lead length
is 7 ft (2 m) for T8 lamps and 3 ft (1 m) for T4
compactlamps
•
Ballast is grounded via case
•

lamp wiring diagrams, see pg. 78.
Features
•
Continuous, flicker-free dimming from 100% to 5%
•
Works with all Lutron Tu-Wire fluorescent controls
for consistent dimming performance
• Sensors cannot connect directly to Tu-Wire ballasts
•
