ELVI Electronic Low-Voltage Interface
DESCRIPTION
• Lets GRX-3000 Control Units and
LP Dimming Panels dim electronic
transformer-supplied low-voltage lighting.
• Provides power and dimming for one zone.
• Models available for 120V, 220 -240V
(non CE), 230V (CE) or 100V input power.
• Works with Lutron’s GRX-3000 Control
Units/LP Dimming Panels/HomeWorks
Remote Power Panels/Neutral-referenced
fluorescent wallbox dimmers by Lutron.

Power
• Input power: 120V, 220-240V (non CE),
230V (CE), or 100V. All voltages 50/60 Hz,
phase-to-neutral.
• Load (output) power:
Phase independent of Control Unit.
Sources/Load Types
• Operates electronic low-voltage lighting
with a smooth continuous Square Law
dimming curve or on a full conduction
non-dim basis.
• – Does not affect sound rating of
electronic transformers.
• – Does not cause lights to flicker or
interact anywhere in dimming range.
• – Dims to 0% (blackout).
• Works only with electronic (solid-state)
low-voltage transformers manufacturerapproved for reverse-phase control
dimming.
• Can handle incandescent and electronic
low-voltage sources on the same zone.
You can use up to 30% of the ELVI’s
capacity for incandescent lighting.
Key Design Features
Patented RTISSTM 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 (2.5mm2).
Environment
32-104°F (0 - 40°C). Relative humidity
less than 90% non-condensing.
Mounting
Surface or recess mount indoors only.
You can use two ELVI Interfaces on a
zone for double the capacity. Use the
HP Dimming Module System for zones
that exceed the ELVI's capacity.

Recess Mount with Faceplate
DIMENSIONS AND MOUNTING
Recess or surface mount in 2-gang U.S.
wallbox 3.5" (89mm) deep. Indoors only.
• ELVI Interface generates heat!
– Mount only where ambient temperature
– is 32-104°F (0-40°C).
– Mount with arrows facing up to ensure
– adequate cooling.
– Allow 4.5" (114mm) 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 (1.8m) from sound or
electronic equipment and wiring.
• Mount Interface within 7° of true vertical.

WIRING
• Pull #12 AWG (2.5mm2) Copper (CU) wires (75°C minimum) for
input power and load circuit.
• Strip 1/2" (12mm) 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.
Single Power Feed
The ELVI Interface may be on the same
circuit as the Control Unit only if the total
load does not exceed the rating of the breaker.

To wire an ELVI Interface to a fluorescent dimmer:
• Run a Neutral wire from the control equipment to Neutral on the ELVI.
• Run a dimmed hot wire from the control equipment to Control on the ELVI.
* Total load on GRX zone = 50W (25 x 2)
* Feeds can be from same feeder if total load on breaker does not exceed breaker
rating.
