I have a 12v 6.67A power supply with a male co-axial plug (with centre pin) that's 7.4mm OD and 5.08mm ID. The metal tube is 12.5mm long.
The pin is recessed and about 1mm in diameter - which seems impossibly small for 6.67A.
A chassis mount socket that would take it would come in handy. But I don't seem to be able to find one. Am I just using the wrong search terms?
Any pointers much appreciated.
Hi everyone, I've just resurrected a broken Weller TCP1 and need a 24v ac supply for it.
I have a 23.5-0-23.5v toroid that I was just going to use half the winding - but it's overkill (8A rating) and going to be very big and heavy.
I've also got a pair of identical transformers with 8-0-8 and a 16-0-16 secondary windings.
I'm thinking of paralleling a 16v winding on each transformer, doing the same with an 8v winding and putting the two in series to give the 24v. However, that leaves two 16v windings and two 8v windings left unused.
Is there any advantage in paralleling those windings also? Any disadvantage? Or just leave them unconnected...Which is what I was about to do..
Sadly I cannot split either winding into two independent ones.
The recent post on using a lamp in series to limit potential fault currents has had me thinking about using them as above. Has anyone done this? I can see advantages, cost for one - wirewound resistors can be expensive. Visual indication of a varying load. Make it "short-circuit proof"..
