Search capacitor for Philips BSX 90 watt SOX ballast « on: August 29, 2021, 09:45:28 AM » Author: Adri_HSI
Hello, dear community, I recently got a Philips BSX 90 H26 ballast for 90 watts low-pressure sodium lamp with a suitable ignition unit. A daisy chain capacitor with 9.6 uF is still required for operation, without it it won't work. Unfortunately, you don't get such a capacitor in Germany and I don't know what else to do :-( Would any of you sell me such a capacitor? The capacitor must have a voltage resistance of at least 300 volts and 9.6 uF I would really be very grateful. Greetings from Bavaria:-)

I have the same ballast but I use two motor capacitors (475V rating) in parallel - one 8uF and one 1.5uF which gives you 9.5uF in total. The lamp runs fine with these both. You’ll find such capacitors for cheap at every electric wholesaler like Conrad, Distrelec or RS components...

[Zitat Autor=Monkeyface Link=Thema=11904.msg96917#msg96917 Datum=1630405324] Ich habe das gleiche Vorschaltgerät, aber ich benutze parallel zwei Motorkondensatoren (475V Nennleistung) - einen 8uF und einen 1,5uF, was Ihnen insgesamt 9,5uF ergibt. Die Lampe läuft gut mit beiden. Solche Kondensatoren finden Sie günstig bei jedem Elektrogroßhändler wie Conrad, Distrelec oder RS-Komponenten... [/Angebot]

Hallo, Affengesicht, das klingt interessant. Soweit ich weiß, dürfen jedoch Motoranfahrkondensatoren nicht dafür verwendet werden. Oder irre ich mich?

Sie müssen Motorlaufkondensatoren verwenden, keine Motorstartkondensatoren.

You need to use motor run capacitors not motor start capacitors.

Ja umbedingt Betriebskondensatoren. Anlaufkondensatoren sind nicht geeignet für diesen Zweck! Zum Beispiel dieser hier: https://www.sonepar.ch/de/578203011-betriebskondensator-hydra-msb-mkp-15400-15uf-400500vac-kabel-ip54-756896

Oh, I'm sorry, I didn't know there was a difference. Then I would like to thank them very much :-) These capacitors are, as they already thought, very easy to get.

   I would get a common 10 uF motor run cap as those caps have 10 percent tolerences as as anything between 9 and 11 uF but it will loose uF over time.

A very slow loss, though. I have a big box of spare capacitors of many different values that I got on eBay from a retiring electrician. I test them all regularly and they are all still well within operational specifications.
