Information About GP16-1204ML-20
The GP16-1204ML-20 is part of Lutron’s GRAFIK Systems GP Dimming Panel family, providing centralized dimming and scene control for multiple lighting circuits. It supports up to 16 load circuits with a maximum output of 2000 W/VA (16 A) per circuit.
The panel is housed in a NEMA Type 1 (IP20) steel enclosure intended for indoor installation. It uses passive convection cooling through a patented ribbed aluminum heat sink base, eliminating the need for internal fans. A built-in 10-year power failure memory restores lighting automatically to the last selected scene after power interruptions.
Key Features:
-
16 Output Circuits: Controls sixteen independent lighting loads from a centralized panel.
-
2000 W/VA per Circuit: Each circuit supports up to 16 A maximum output capacity.
-
120/208 V Input Rating: Designed for 3-phase, 4-wire electrical distribution systems.
-
175 Amp Input Capacity: Supports high-capacity panel feed for multi-zone installations.
-
Main Lugs Only (ML): Allows direct feed connection without integrated main breaker.
-
Square Law Dimming Curve: Provides continuous dimming performance for compatible lighting sources.
-
Convection Cooling Design: Ribbed aluminum heat sink enables passive cooling without mechanical fans.
-
10-Year Memory Retention: Restores last selected lighting scene after extended power interruption.
The GP16-1204ML-20 delivers the reliability and precision required for integrated scene-based commercial lighting control systems.
