Retrofit GP Dimming Card
• The Retrofit GP Dimming Card is intended to be used
by customers who are currently using a GP dimming
panel to dim screw-in incandescent lamps but wish to
retrofit their system with more energy efficient screw-in
replacement LED lamps.
• Certified for use in North America and will control up
to 300 W of forward-phase controlled 120 V~ LED
lamps. Although it is capable of operating other load
types (see Specifications on page 2) it is intended to
operate LED lamps only.
• Offers a solution for driving compatible LED lamps that
are affected by the slow rise time or voltage ring-up
caused by the large GP inductor.
• Uses the switched-hot terminal to bypass the existing
inductor without removing or replacing the wiring
harness.
• Functions as a drop in replacement for the existing
dimming card; requires a simple relocation of the
dimmed-hot load wire to the switched-hot terminal.
• Provides better low-end dimming performance and
more stability for a greater number of LED lamps than
does the existing panel. For recommended LED lamps,
refer to Application Note #507 at www.lutron.com/

Key Design Features
• Lightning strike protection: Meets ANSI/IEEE standard 62.41-1980. Can withstand voltage surges of up to
6000 V~ and current surges of up to 3000 A.
• Holds light levels if data is interrupted; goes to full conduction if power is restored without data present.
• RTISS
® filter circuit technology: Compensates for incoming line voltage variations.
• Arcless-relay, air-gap OFF switch (one per load circuit): Ensures open load circuits when OFF function is
selected; eliminates arcing at mechanical contacts when loads are switched.
