What is a series compensation capacitor?

"Series" compensation. of the mains (420-440 V) and a temperature range of -25+85° C, up to 100° C for some applications. It must also be considered that a switch-on voltage transients may occur on the capacitor; their size depends on the type of lamp and they must be considered when selecting the capacitor.

Why do you need a capacitor?

International regulations also impose this obligation for capacitors, in order to avoid the risk of explosion or fire which could occur in case of especially critical operating conditions or at the end of the working life.

Where is a capacitor on a fluorescent lamp?

T.k Where have you seen a capacitor across the supply to a fluorescent lamp? There are two caps. One is inside the starter for EMI suppression during the inductive kick. There is also another capacitor for power factor correction between the line and neutral.

Can a capacitor withstand a steep wavefront?

The capacitors are capable of withstanding steep wavefronts with a maximum voltage variation speed of20 V/μs (dv/dt). The very widescale use in all sectors of fluorescent lamps implies particular care over safety requirements. of the accident.

Can a capacitor be used at a higher frequency?

The capacitors can be used at a frequency range of 50-60 Hz. Use at higher frequencies is possible provided the voltage, current, temperature and power limits are complied with. In accordance with the reference standards, the temperatures are those measured on the surface on the capacitor. -40°...+ 85°C. Rated tolerances, ±5%, ±10%.

Do you need a circuit for an energy saver bulb?

You need the circuit of an energy saver bulb whose tube is burnt or damaged. This is a high voltage and high frequency generating circuit, be careful there is high voltage present if you connect it to AC line. There is a high voltage input capacitor (from 2.2uf to 10uf 400 volts).
