The PLN22A W W/0 LAMP is a form of electronic ballast that is designed to power high-frequency fluorescent lamps without a lamp starter. It features overload protection, soft start circuitry, and auto restart in case of power interruption. The PLN22A uses power factor correction to reduce total harmonic distortion. It works with both single- and double-ended T12 and T8 lamps, as well as 25W, 32W, and 40W T9 lamps. It is suitable for use in wide range of applications, such as retail, hospitality, and healthcare environments.
