Retrofit GP Dimming Card
• The retrofit GP dimming card controls high‑efficacy
loads and can be retrofitted into existing GP panels in
North America.
•
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 it 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.
Retrofit GP Dimming Card works with

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.
