Philips Advance T5 Fluorescent Ballast - 120-277V AC | Dimmable | Programmed Start

IZT-2S28-D-35M (108936) is the Philips Advance T5 Fluorescent Ballast. When servicing a socketed fluorescent fixture, compare this model against the lamp schedule and supply before ordering. The 2 X F28T5 operating configuration distinguishes this ballast from versions intended for a different lamp count. The programmed start starting arrangement is part of the compatibility check for the installed lamp circuit. When comparing replacements, note the 1 ballast factor as well as the lamp and supply ratings.

Use the 120-277V AC version only where the supply and control arrangement suit its electrical specification. For the ballast compartment layout, allow for the listed length 16.70 in., width 1.18 in., height 1.00 in. and the installation clearances required by its instructions. Follow the wiring diagram for this model when making the replacement connections.

Buying tip: Match the lamp designation, number of lamps and supply voltage to the existing ballast.
