CP 15BU28 supplementary capacitor is an AC capacitor designed for individually correcting the power factor of transformers and magnetic ballasts in discharge light sources (such as fluorescent lamps, halogen and ceramic metal halide lamps, high-pressure mercury lamps, and sodium lamps) at line frequencies of 50 or 60Hz. This improves the power factor of the light sources, with cosμ exceeding 0.85.
This two‑page datasheet lists the key electrical and mechanical specifications of the Philips CP 15BU28 capacitor used in HID lamp circuits. It includes rated voltage, frequency, temperature range, capacitance tolerance, power factor and detailed dimensions.
The document also provides packaging details, weight, bar‑code numbers and compliance markings such as ENEC, GB standards and VDE. It is intended for designers and distributors needing precise product data. This manual is written in Chinese.
