Philips Advance T5 Fluorescent Ballast - 0-10V | Dimmable | Programmed Start

The Philips Advance T5 Fluorescent Ballast, model IZT-2S24-D-35M (502369), is the component described here. This model is a replacement ballast for the matching fluorescent lamp circuit. Select it from the lamp schedule inside the existing fixture. The listed lamp configuration is 2 X F24T5HO, which should be checked as a complete lamp-and-count combination. This is the programmed start version, so the fixture wiring and lampholder arrangement must suit that starting method. Ballast factor 1 is one comparison point for retaining the intended lamp output in this fixture.

Plan the electrical connection around this model’s 120-277V AC rating. The listed body dimensions are length 16.70 in., width 1.18 in., height 1.00 in.; use them when checking the available space around the ballast compartment. Follow the wiring diagram for this model when making the replacement connections.
