GRX-PWM Pulse Width Modulation Interface
Description
• Provides capability for a GRAFIK Eye 3000 Series control
unit, GP, or LP Panel to switch and dim fluorescent lights
that have pulse width modulating (PWM) dimming ballasts.
• Switches and dims any PWM fluorescent dimming ballast
powered by 100-277 V that conforms to JISC8120-2.
• Switches up to 16 A of fluorescent, incandescent, low-
voltage, metal halide neon/cold cathode load.
• Switches motors up to 1/4 HP @ 100/120 V , 1/2 HP @
200-277 V
• Up to five PWM interfaces may be connected to one
GRAFIK Eye 3000 control unit zone. This allows one zone to
control up to five 16 A circuits of electronic dimming ballasts
or five motors.
• Switches 100-277 V 50/60 Hz power to loads.
• Requires 100/120 V 50/60 Hz power for internal
operations.

Dimensions and Mounting
• Mount only where ambient temperature is 32-104 °F ( 0-40 °C); less than 90% non-condensing relative
humidity.
• Allow 4.5 in. (114 mm) between interfaces when mounting several in a vertical layout.
• Mount so that line (mains) voltage wiring is at least 6 feet (1.8 m) from sound or electronic equipment and
wiring.
• Mount within 7° of true vertical.
• Internal relays click while in operation; mount where audible noise is acceptable.
All dimensions in inches (mm).
