ANSI C82.11-2023 PDF

This standard is intended to cover high frequency ballasts that have rated open-circuit voltages of 2,000 volts or less, operate the lamp at frequencies between 10 kHz and 500 kHz, and are intended to operate at a supply frequency of 50 Hz or 60 Hz. This comprises ballasts for hot-cathode fluorescent lamps, either switch-start (preheat-start), rapid-start (continuously heated cathodes), modified rapid-start, programmed-start, or instant-start used primarily for lighting, germicidal, or industrial purposes. The ballast and lamp combinations covered by this specification are normally intended for use in room ambient temperatures of 10°C to 40°C. At ambient temperatures outside this range, certain special operating characteristics may be required.
