ADVANCE Electronic Fluorescent Dimming Ballast, Universal 120V-277V Input, Operates 2 F24T5/HO, F39T5/HO, FT24W/2G11 Lamps, Analog Dimming 5-100%, Programmed Rapid Start Ballast

Advance Mark 10 IEZ-2S24-D Electronic Dimming Ballast (F24T5/HO)

The Advance Mark 10 Powerline IEZ-2S24-D by Signify is a high-performance electronic dimming ballast designed to operate one or two F24T5/HO lamps. Utilizing 2-wire phase-cut dimming technology, it works seamlessly with compatible Mark 10 dimmers without the need for additional control wires, making it perfect for retrofits. Featuring Universal 120-277V input and Programmed Start circuitry, this ballast ensures smooth, continuous dimming and extended lamp life for architectural, commercial, and retail applications.

Core Specifications & Features

• Supported Lamps: Operates 1 or 2 F24T5/HO (24W) fluorescent lamps.
• Dimming Protocol: Mark 10 Powerline (2-wire phase control). Allows you to dim fixtures using existing power lines without pulling separate 0-10V low-voltage wires.
• Dimming Range: Provides smooth, continuous dimming from 100% down to 5% relative light output.
• Input Voltage: Universal IntelliVolt 120-277V, 50/60 Hz.
• Starting Method: Programmed Start gently preheats lamp cathodes before ignition, drastically increasing lamp lifespan during frequent dimming or switching cycles.
• Safety & Compliance: UL Listed (Class P, Type 1 Outdoor), CSA Certified, RoHS Compliant, and features built-in Lamp End-Of-Life (EOL) protection.

Electrical Performance Data

Frequently Asked Questions

What is the difference between Mark 10 Powerline and Mark 7 0-10V dimming?

Mark 10 Powerline uses standard 2-wire phase-cut dimmers, meaning the power and the dimming control are sent over the exact same existing hot and neutral wires. Mark 7 ballasts require you to pull two extra, dedicated low-voltage wires (a 0-10V circuit) to carry the dimming signal.

Can I use this ballast to upgrade a standard non-dimming fixture?

Yes! Because the IEZ-2S24-D does not require extra control wiring, you can replace a standard ballast with this unit using your existing fixture wiring, provided you also replace the standard wall switch with a compatible Mark 10 dimming switch.

Does this ballast support End-of-Life (EOL) protection?

Yes, it includes integrated Lamp EOL protection. This safety feature shuts down the circuit when a lamp reaches the end of its usable life, protecting the fixture and sockets from potential overheating.
