I've used Hirschmann G30 series in the past - very good, locking (bolt through the middle) and a very reasonable price:

These are nominally industrial valve control connectors ...

Hmm. Is that 500V pin-to-pin or pin-to-case?

You can also run the pre-regulator sense wire to the base of the secondary regulator - it's not a Kelvin connection, but is the generally accepted way of ensuring the right voltage is delivered to where it's being used.

Twisting the appropriate wires and screening the umbilical also can help, as ...

42 arguably more so though perhaps?

NJL3281D/NJL1302D now back in stock from the usual suspects.

Pretty sure the reverse protection diode, D1, is not needed in this use case - the LT1085 datasheet is pretty clear. Also, for stability the regulator output cap, C6, is specified at a minimum of 22uF solid tantalum or 150uF Aluminium electrolytic - the capacitor multiplier will not be involved in ...

After many many years of faithful service, my Peak DCA 55 and LCR 40 are being replaced with the newer versions... I need the higher test current of the DCA 75 Pro, particularly for thyristors, so took advantage of an offer and upgraded both.

The existing ones, which are in perfect condition ...

"Trail camera" is the more common name.

I have some of these and they're ok.

Looks like a Marx Generator stack.

Nice toys!

I perennially found Peak instruments with flat batteries both at work and at home, hence the boxes. A moment ago, I was going to look in the menu to gag the beeper, but when I switched my DCA75 on, it chirped at me then said "low battery". :D


In 10 years or more of having Peak DCAs and LCRs, I ...

Don't be in too much of a hurry to get rid of the DCA55. My DCA75 Pro irritated me (beep) and has been relegated to the back of the drawer, with the DCA55 and ESR60 at the front. Peak testers fit nicely in small baby bud boxes, protecting them from being switched on and flattening their batteries ...

On the DCA75, you can turn the beeps etc off from the menu. I need specific capabilities of the 75, so the 55 will go.

I've never had one turn on accidentally - maybe I'm just kinder to mine

...however on a happier note, spent a wonderful morning in Denge with an excellent lecture to boot:

The sound mirrors are on my 'to do' list. We've done Abbots Cliff nearby but not Denge (yet).


Just go for it ...
