PHILIPS ADVANCE MARK 7 0-10V | IZT-2S28-D | 2-Lamp F28T5 | 120-277V

Philips Advance Mark 7 0-10V IZT-2S28-D is a high-performance dimmable electronic ballast designed for precision control of T5 fluorescent lighting systems. Part of the industry-leading Mark 7 series, this ballast offers a full dimming range from 100% down to 1% light output, making it an essential component for energy-saving strategies like daylight harvesting, load shedding, and occupancy sensing. Utilizing IntelliVolt technology for 120V to 277V operation, it features Programmed Start circuitry to maximize lamp life in frequently switched environments. This low-profile ballast is the professional choice for commercial offices, schools, and institutional buildings requiring versatile, flicker-free dimming and superior energy efficiency.

Product Overview

The Philips Advance IZT-2S28-D is a vital component for modern smart-lighting ecosystems. By supporting standard 0-10VDC control protocols (Class 1 or Class 2), it allows facility managers to implement sophisticated light-level strategies that significantly reduce energy costs. The Programmed Start technology ensures that cathodes are properly preheated before ignition, which is critical for maintaining lamp integrity in buildings with automated occupancy controls. Its slim, low-profile case design is perfectly suited for linear fluorescent pendants and cove fixtures, while integrated End-of-Lamp-Life (EOL) protection safely removes power at the end of the lamp cycle to prevent overheating.

• Precision Dimming: Smooth, flicker-free dimming from 100% down to 1% provides tailored illumination for any task.
• Sustainable Design: Facilitates LEED certification and energy code compliance (Title 24, ASHRAE 90.1) through advanced control compatibility.
• IntelliVolt Technology: Automatically senses and operates at any input voltage between 120V and 277V, 50/60Hz.
• Quiet Operation: Class A sound rating and low Total Harmonic Distortion (≤ 10%) ensure a silent environment for quiet commercial spaces.
