GE B239PUNV-DOG1C 2-Lamp F39T5HO Rapid Start Ballast 120/277V 50/60Hz

SKU CH-P9E3-MP94W MPN B239PUNV-DOG1C

Rapid-start electronic ballast operates two F39T5HO fluorescent lamps on 120–277 V, 50/60 Hz circuits

  • Drives two F39T5HO lamps with rapid start
  • Operates on 120/277 volt multi-voltage supply
  • Electronic ballast runs at 50/60 Hz frequency
  • Normal ballast factor maintains standard light output
  • GE model B239PUNV-DOG1C built for fluorescent fixtures

Product Identity

This GE B239PUNV-DOG1C ballast drives two F39T5HO fluorescent lamps using rapid start technology. It suits maintenance teams and installers who service existing T5 high-output fixtures in commercial or institutional buildings.

Electrical Flexibility

The unit accepts a 120/277 volt supply at 50/60 Hz, allowing the same ballast to be stocked for multiple North American service voltages. Electronic circuitry provides normal ballast factor for standard light output without special wiring requirements.

Operational Profile

Electronic operation runs the lamps at high frequency to eliminate visible flicker and audible hum associated with magnetic gear. Power draw remains consistent across the dual-voltage range, and the rapid start method reduces electrode wear during frequent switching cycles.

Questions about this item

What lamp wattage and type does the B239PUNV-DOG1C ballast support?

The B239PUNV-DOG1C supports two F39T5HO fluorescent lamps, each rated at 39 watts, using rapid-start electronic operation.

What input voltage range does the GE B239PUNV-DOG1C require for installation?

The ballast operates on 120 to 277 volts at 50 or 60 Hz, so it fits standard North American commercial lighting circuits without a transformer.

How is the B239PUNV-DOG1C wired during installation, and what common mistake should be avoided?

Wire the ballast in parallel to both F39T5HO lamps following the rapid-start diagram; the frequent error is using a series or instant-start wiring scheme, which prevents proper lamp ignition.
