Philips Advance IOPA-1P32-N Ballast

This electronic fluorescent ballast drives a single T8 or T8U lamp at 17, 25, 28 or 32 watts. It accepts a wide 120 to 277 volt AC input, making it suitable for commercial and residential lighting retrofits. The Optanium design provides instant start operation without dimming capability. Minimum starting temperature is rated at -20 degrees F for cold environments.

Installation notes

Wiring follows standard instant-start ballast practice with one lamp connection. The multi-voltage input eliminates the need to match a specific supply voltage. A common error is connecting lamps outside the supported wattage range or using incompatible bulb types such as T12. Verify the lamp holder wiring matches the single-lamp diagram before energising the circuit.

Sustained operation

Under continuous load the ballast maintains stable lamp current across the full input voltage window. The instant start method delivers full light output immediately without pre-heat delay. Operating temperature remains within design limits during extended run times. The lack of dimming circuitry reduces component count and potential failure points in long-term service.

Questions about this item

How do I confirm the IOPA-1P32-N is operating correctly after wiring it to a T8 lamp?

The lamp should start instantly at the rated wattage — 17 W, 25 W, 28 W or 32 W — with no flicker, even at -20 °F, and the ballast case should remain at a normal warm temperature during operation.

What comes with the IOPA-1P32-N and what must I supply?

The ballast itself is included; you must provide a compatible T8 or T8U fluorescent lamp (17 W, 25 W, 28 W or 32 W), supply wiring for 120-277 V AC input, and a suitable fixture or enclosure.

Which wattage version of the IOPA-1P32-N should I select for my T8 lamp?

This single model covers 17 W, 25 W, 28 W and 32 W T8 or T8U lamps — choose the lamp wattage you are installing; the ballast automatically supports any of those four ratings.
