NEED: 6.0uF 1200Vdc capacitor

[Barry & Nikki]

Labeled: Plessey Ducon pulse grade capacitor part number p200. Made in
Australia. I need this or a compatible replacement. It's a round "barrel"
with two wire leads (blue and brown). The housing is about 2" in length and
1 1/4 in diameter. Please email me if you can help. Thanks in advance for
any help anyone can offer.

The P200 would have been a polypropylene film type. That's a fairly

ancient one... Plessey, the UK parent company which bought Ducon
Australia in 1963, folded in late 1989 and I think GEC Siemens
subsequently took them over. Even Siemens has hived off their
capacitor manufacturing business.

You haven't said what item of equipment this capacitor is mounted in
or what its function might be. Is it on the ac mains side of the
circuitry?

If it is on the ac side of things then you could possibly use an ac
capacitor of say 280Vac rating such as that made by ASC Capacitors
http://www.ascapacitor.com/ but until you supply the information this
could be an incorrect guess.

If I am correct then the 6.0uF, 280Vac unit shown on this data sheet
would be suitable http://www.ascapacitor.com/PDF/X391L.pdf

You will have to locate your local ASC distributor.

Didn't figure that info really mattered. I was looking for an exact or
equivalent. I realize its old stock; but if it really matters it is out of
the main portion of an electric fence circuit board.

1200Vdc (see original post) is not exactly high voltage (up to 1500Vdc
is still classed as low voltage) so the Maxwell units which start at
9kv are not appropriate.

You have reluctantly now told us that the item containing the
capacitor is an electric fence charger but you fail to give any brand
or model details. All one can do with what you have provided is to
make an intelligent guess.

If I had posted a request that said I wanted a fuel pump for my car in
order to repair it, then this would have been quite rightly greeted
with derision. The make, model, year etc would be mandatory
information to supply in order to get any help and your query is in
the same category.

Given the probable age of your fence charger (or the capacitor in
question) plus the fact that the manufacturer of that capacitor hasn't
been in existence since about 1989 then the likelihood of getting the
same unit is highly improbable. The fact that the capacitor is of
Australian origin suggests that the fence charger is also Australian
made as well, but you haven't provided any details related to the
manufacturer. Since Plessey Ducon no longer exists, and the data on
this particular capacitor is no longer available, then the more
information you provide the better able anyone is to suggest an
alternative.

The application to which a capacitor is put is extremely relevant when
trying to determine a replacement. The only flexible wire leaded
cylindrical polypropylene capacitors made by Plessey Ducon were
produced for the power industry for flourescent lighting power factor
correction and motor start/run applications, so the unit you are
trying to replace is most likely one of those, but just why it is
marked with a dc voltage rating is not clear. These capacitors were
commonly used in strobe lighting and fence charger applications.

I am guessing that the capacitor is used as the charge storage
capacitor which is then dumped periodically into the output
transformer of your fence charger. Depending upon the output voltage
of the dc-dc converter in the charger, and the turns ratio of the
output transformer, we can only make a guess as to the ac voltage
rating of a similar capacitor manufactured currently.

Around the mid 80's the Australian standard AS3129 for fence chargers
specified that the maximum voltage allowed to be connected to a fence
was 5kV into a 1 megohm load, plus other pulse timing and allowable
current details. Also, there was only one Australian manufacturer that
I am aware of (Jones Transformers model JT349) making an output
transformer specifically for fence chargers and this had a ratio of
about 1:20(P:S). This allowed for a dc-dc converter having 250Vdc as
the output voltage to charge the storage capacitor.

Not having any specific details of your fence charger all I can say is
that a circuit design I have to hand with these same specifications
and using this output transformer specifies a metallized paper or
polypropylene capacitor specified for high current pulse operation,
rated at 250Vac - 440Vac and between the values of 6.0 - 25uF. Such
capacitors will safely handle dc voltages from 400V and above, which
your dc-dc converter is unlikely to produce.

Here is some data on current Australian capacitors similar to the one
you are looking for
http://www.tridonicatco.com.au/Medien/cat0304_au/Capacito.pdf

All you have to do now is find something similar where you are located
so surely you are capable of doing that.

There is always one in a group. How about I give you my wife's
measurements as well? Geez, I understand about needing all the info on a
vehicle but we are talking about a SPECIFIC capacitor here. I gave size
restraints as well as the exact values it possesses and even as far as to
what item it is in. As to knowing what EXACT manufacturer I am not sure
being I am doing this as a favor for a friend.
I hate to burst your bubble but you do not know everything being the
charger was NOT manufactured in Australia. Ever heard of the word IMPORT. as
in importing of goods. Well it happens with electronics as well and
apparently some components were imported being it was manufactured in the
U.S.A. But I have to admit you are correct in assuming it is an older
charger but not old enough to where it is obsolete.
Just forget I ever asked, apparently you want to dazzle everyone with
your knowledge and rantings on needing an over abundant amount of info.
Apparently anyone who knows there stuff doesn't need to know every detail to
be able to help being I have had some very useful help from others here who
obviously can make a logical conclusion based on SPECIFIC info given.

It is common courtesy to give as much information as possible to make
it easier to provide the CORRECT information. It is not as though I
can actually see the item the capacitor is in or what it's function
might be. Just saying 6uF, 1200Vdc Plessey Ducon is not enough.

You gave the basic details of the capacitor but as I explained (in a
rather verbose manner) IT IS NOT POSSIBLE to give a direct equivalent
for it UNLESS THE ORIGINAL DATA IS AVAILABLE. Since this data is not
available then a guess has to be made depending upon WHERE in the
circuit it is used and WHAT FUNCTION it performs. Because capacitors
with the same physical shape and having long flexible wire leads are
ALWAYS rated in AC VOLTS by current manufacturers world-wide, the
problem is much more complicated than you think. The fact that it had
a 1200Vdc rating makes it more difficult because you won't be able to
find one of this type anywhere with a DC rating today.

As to knowing what EXACT manufacturer I am not sure
being I am doing this as a favor for a friend.

I only said that it SUGGESTS that the item was made in Australia, not
that it WAS manufactured in Australia. It seems strange that a country
which is overzealous in protecting its own manufacturing industries
would allow products made in Australia to be used in a locally made
fence charger(I assume it is USA made?), especially when there were
many local manufacturers of similar capacitors in the USA at the time
the charger was manufactured. My guess is that the fence charger
manufacturer bought up a load of NOS which was available after Plessey
Ducon folded.

U.S.A. But I have to admit you are correct in assuming it is an older
charger but not old enough to where it is obsolete.
Just forget I ever asked, apparently you want to dazzle everyone with
your knowledge and rantings on needing an over abundant amount of info.

I notice nobody else has tried to help you so that suggests that you
haven't been very forthcoming with the required information they need
to put in a suggestion.

Apparently anyone who knows there stuff doesn't need to know every detail to
be able to help being I have had some very useful help from others here who
obviously can make a logical conclusion based on SPECIFIC info given.

Completely incorrect. There are literally hundreds of capacitor types
many of which can be used only for specific purposes. The function of
your capacitor is indeed quite specialised and you can't use just any
capacitor. It HAS to be rated for high current pulse duty with an
extremely low disssipation factor. You only grudgingly released the
information that the item was a fence charger but not WHICH PART of
the circuit it is in, so in order to suggest the correct replacement,
specialised knowledge was required to GUESS that the capacitor was
used to provide high current dc pulses to the primary of a pulse
transformer. Since you won't be able to buy the capacitor type you
want with a DC voltage rating anywhere today, then how would you
suggest anyone would be able to help find a replacement?

You are an ungrateful sod aren't you. I have correctly given you all
the information you need after having to prise the barest necessary
information out of you with a stick. I just can't give you a specific
make and model other than I have done already because I don't know
what is available where you are.
