krybespænding på output 230VAC moduler

[Mikael Offersen]

Hej alle kloge hovederJeg undrer mig over hvorfor det er muligt at måle spænding i installationen, på lampeudtag osv, der er forsynet fra et 230 v outputmodul, og hvorfor spændingen svinger mellem ca 80V til 160V - vel at mærke når der skulle være slukket...Jeg mener, modulet er vel opbygget af små relæer indeni, det er vel ikke triac'er eller andet elektronik-stads der slutter, når udgangen går ON???Det er muligt at det har været diskuteret før, har bare ikke kunne finde det i foraet, håber det er okay?Med venlig hilsenMikael

Er nok induktiv spænding du kan måle... En lampe kan du sikkert ikke få til at virke? ;-)

Hi,Sorry this is in English, but my Danish isn't that good yet.I have noticed something similar with a Wireless Kombi Relay when connected to an energy saving flourescent bulb. When measuring across the bulb I a can see in the OFF state that voltage ramps up to around 100v, the bulb flashes, voltage drops and the cycle repeats. I believe this is due to the relay in the LK product having an interference suppression capacitor fitted across it's terminals, which is charging up. The current is very small and not enough to light a conventional bulb, but it does seem to be enough to cause some energy saving bulbs to flash about once every 10 seconds.My solution was in the first instance to use another make of bulb (Philips didn't have a problem, but certain OSRAM bubls did I seem to remember). In the second instance I have used the same module to drive more bulbs in parallel so there is less leakage current to each bulb.Hope this helps,Christian
