Component wiring polarity question

[dagoof]

Quick question, I've got a suppressor on a piece of equipment that has blown, I've received the replacement suppressor but the wiring format is slightly different (attached).
The new model has P(DC+) and P'(DC+') whereas the old one has L1 and L2.

Am I correct in thinking
L1 = P(DC+)
L2 = P'(DC+')

?

The new model has P(DC+) and P'(DC+') whereas the old one has L1 and L2. Am I correct in thinking .... L1 = P(DC+) .... L2 = P'(DC+') ?

The meanings of P(DC+) and P'(DC+') are clear enough from your photo, but we have no way of knowing what the old one's L1 and L2 referred to.

What about the other two terminals [ N(DC-) and N'(DC-') ]? Did your old suppressor have corresponding terminals with wires attached to them?

Kind Regards, John

Yes, that's correct John (re. negative terminals). On the old suppressor, the cable used for L2 was lacquered (as was the N3) so I thought I could tie them up by process of elimination.

Sheds - AC/DC issue?

 

[ban-all-sheds]

Your old one did not have negative terminals. Or positive.

Apologies for any confusion I may have created. Due to some vagaries of this site, the first image was not visible to me in the original post, but I do see it in BAS's reproduction of the images.

As for the point which has been highlighted, both the old and new suppressors are rated for 250V 50/60Hz (AC). The fact that the new one also gives a DC rating does not alter its suitability.

Kind Regards, John

 

[dagoof]

No worries John - yes, I saw it's also had AC so didn't think DC rating effected matters.

Sheds - does that mean the part is not a compatible replacement?

 

[ban-all-sheds]

both the old and new suppressors are rated for 250V 50/60Hz (AC).

Oh, FGS.

It's our old friend.

Are we sure that the problem is weserv, rather than that the image in question was a .gif ?

 

[ban-all-sheds]

I would venture to suggest that if weserv cannot serve GIFs then the problem is weserv.

 

[JohnW2]

Whatever, I still don't really understand the "FGS" comment which accompanied the image in question.

 

[ban-all-sheds]

Self-admonition for somehow not seeing the AC rating on the device, and somehow only seeing "250VDC".

Any ideas on the cable config then?
