120PSB-

120PSB (Pulse Start Ballast) is a type of ballast used to create a starting voltage for high-intensity discharge (HID) lamps. It is a high-efficiency ballast that provides a longer life compared to standard ballasts. HID lamps require a higher voltage to be ignited and this is where 120PSB comes in – it works to provide that higher voltage in order to start the lamps.

HID lamps, which include metal halide, mercury vapor, and high pressure sodium lamps, are used in many applications such as street lights, warehouse lighting, parking lots, and agricultural applications. The output of these lamps is much higher than incandescent and fluorescent lamps. Because of their efficiency, they are often used in commercial or industrial settings.

The working principle of a 120PSB is that the initial voltage is generated through a series of transformer stages. The voltage generated is then amplified by an amplifier and then switched to generate a higher pulse voltage. This high voltage is used to create a spark inside the lamp, which starts the lamp. In this way, a lamp that requires a higher voltage can be ignited and operated.

There are several benefits to using a 120PSB ballast, namely: longer lamp life, improved energy efficiency, reduced lamp costs, and improved starting characteristics. Longer lamp life is caused by the gap between the ignitor voltage and the peak voltage being shortened. This reduces the number of ignitions per start, thus increasing lamp life. Improved energy efficiency is caused by the pulse start feature, which helps save energy by reducing the running time of the lamp. Additionally, reduced lamp cost is due to the higher efficiency and increased lamp life of the 120PSB. Finally, improved starting characteristics are due to the ballast producing more consistent spark energy over its operating life.

Overall, 120PSB is a type of ballast that is used to start high-intensity discharge (HID) lamps. It works by providing a higher starting voltage than standard ballasts, and its advantages include increased energy efficiency, improved starting characteristics, longer lamp life, and reduced lamp cost.
