ICN-3TTP40-SC Advance Centium Electronic CFL Ballast - 2 or 3 FT40W/2G11 Lamps

What is the Philips Advance Centium ICN-3TTP40-SC Ballast?

The ICN-3TTP40-SC is a Centium series electronic fluorescent CFL ballast manufactured by Philips Advance (Signify). It is primarily engineered to operate two or three 40-watt twin-tube CFL lamps (FT40W/2G11), offering critical advantages including IntelliVolt universal voltage (120-277V), high-efficiency instant start ignition, and Lamp Striation Reduction (LSR). It is the optimal choice for multi-lamp commercial fixtures in offices, retail spaces, and medical facilities requiring dependable, energy-efficient illumination.

Core Features and Technical Advantages

Selecting a premium Centium electronic ballast ensures maximum energy efficiency and operational flexibility for your high-output fluorescent fixtures. The primary features of the ICN-3TTP40-SC include:

• IntelliVolt Technology: Automatically detects and adapts to any line voltage between 120V and 277V (50/60Hz), simplifying retrofits and reducing the need to carry multiple voltage-specific ballasts in inventory.
• Lamp Striation Reduction (LSR): Features advanced circuitry designed to minimize the visual flickering or "snaking" effect common when starting cold fluorescent tubes, ensuring consistent and stable light output instantly.
• Instant Start Efficiency: Delivers maximum energy savings and immediate illumination upon powering. It provides a normal ballast factor with Total Harmonic Distortion (THD) under 10% for highly efficient power utilization.

How to Verify Compatibility for Your Fixture

When evaluating the ICN-3TTP40-SC for a commercial lighting repair or retrofit, assess the following criteria to ensure complete compatibility:

1. Lamp Type and Quantity: Confirm your fixture utilizes 40W 4-pin long compact fluorescent lamps (FT40W, PL-L40W, or 2G11 base). This specific model is engineered to power two or three of these lamps simultaneously.
2. Switching Cycles: Because this is an instant-start ballast, it is highly recommended for long-burn applications (lights kept on for extended periods). 
3. Housing Dimensions: Verify that the low-profile SC-can metal housing (9.5" L x 1.7" W x 1.18" H) securely fits within your fixture's internal ballast compartment.

Frequently Asked Questions

What lamps are compatible with the ICN-3TTP40-SC?

This ballast is designed strictly for standard FT40W/2G11 and PL-L40W/2G11 long twin-tube compact fluorescent lamps (4-pin). It successfully operates standard 40W models, as well as energy-saving and rapid start variants of the 40W twin-tube CFL.

Can this ballast operate fewer than three lamps?

Yes, the ICN-3TTP40-SC is incredibly versatile and can safely operate  two or three lamps. Installers should always refer to the wiring diagram printed directly on the ballast label to ensure the proper wiring configuration based on the number of lamps being used.

What is the difference between ICN-2TTP40-SC and the ICN-3TTP40-SC ballast?

The ICN-2TTP40-SC operates one or two lamps while the ICN-3TTP40-SC operates two or three lamps
