chassis-mounted filter or IEC plug filter

[jarthel]

I'm thinking of getting one. I might also get an ordinary chassis-mounted filter as I already bought an IEC plug. I'm not sure but would a chassis-mounted filter do the same job as an IEC plug filter.

If I do use a chassis-mounted filter, is the metal casing connected to the mains ground?

Also, how do I select one based on amperage? It comes in 2A, 4A and 6A. I'm thinking of getting the 6A.

Also, I've seen in catalog where a chassis-mounted filter has an earth line choke. what is it?

Any ideas/suggestions are greatly appreciated.

Thanks

Most likely a good thing to have.

Thanks for the link.

But it didn't solve my problem on choosing one. I'm thinking of getting one with 6A rating. Is this a good choice?

Thanks

jarthel,

that depends on the power rating of the equipment you want to use it for. 6A would give about 1380VA (230V mains) or 660 VA (110V mains). So if its a nice ower amp with two 600VA transformers and you have 110V mains the 6A wouldn´t do.

it's only for a headphone amp. In that case, 1A maybe be enough. right? Also, are IEC plug filters and chassis-mounted filters the same? I would really like to get the chassis-mounted if possible as I already have an IEC plug.

Thanks

ps. I don't need links to manufacturers as I already have one in mind and it may not be available to Australia. I just need to decide on what type to buy. Thanks again.

Hi,

there are lots of different types (damping, frequency) both in an IEC plug or chassis mounted. The only advantage of an IEC plug is that you don´t need extra wiring.

It really depends on what kind of filter it is.
Usually as rule chassis filters are better because they have a much larger circuit with better filters. Don´t buy any asian filters, they tend to be cheap in quality. For 1 amp you could use an IEC type filter if it of a good brand.

thank you for the replies.
