220 Volt Panel

[meirgerner]

Hi guys
I have a new (one year) Hunter 33 and during the last few months I had few LED indicators of the 220Volt (I am in Israel using 220V as main power !) burned out one by one. When opened the 220Volt box I noticed that the LED Indicators are directly connected to the 220V source, which looked to me very strange. I was looking for a rectification circuit and a resistor. When openning the LED "sleeve" I found a 75-KOhm resistor, with no rectification circuit.
I wonder if any of you had a simmilar problem and if you have any information about this circuit :[/ATTACH]
Does anyone know where can I find the updated electrical schematics of the Hunter 33. (I have the ones from 2005).
Any information will be appreciated
Please email to: meirgerner@gmail.com

try digiKey

They have most anything elecronical you could want. I prefer the catelog as it is easier to use than their web search. I know they have the yellow 220 volt leds in several sizes.

Are you SURE they are LEDs? My 1996 H376 has LEDs for the 12V circuits and neons for the 220 V AC switch indicators.
Also a 75 K resistor will only pass 3 mA at 220V and this would hardly light a LED but would be normal for a 110V AC neon. The neon would be rather over running on 220V as most neons indicators run at about 1mA, the neon voltage being between 90V and 110V.
Also this might be the reason for failure as they go black inside the glass envelope.
I suggest replacing them with 220/240V indicators.

Tjanks guys. The manufacturer of the 220Volt box is Ultra Panel. I tried to contact them to get support but had no response. Any idea with whome there Ishould contact?
Another question: how can i tell the difference between Neon and LED componets?

I used

upm01@netrox.com

and spoke with Ana to get some replacement LEDs for my panel a few months back...

their phone number is 305 888-7709.

Thanks.
I have tried Ana and have not got any response yet... I will tryto call her.
BTW, did you have similar problem of LED's burned out? Did you get a satisfactory response from Ultra Panels? I will try to get the Electric Circuit schems of the Main AC box, as, to the best of my understanding, one resistor in line with the LED will not do thejob for the long run (there must be a diod in parallel and reverse to the LED and a Resistor Capacitor bridge in line)
