24volt DC power supply for defibrillator

[slingshot2000]

Hi gents,
I am after a bit of advice on sourcing a 24volt 70watt DC power supply for a public accessible defibrillator.
Do you think either of these would be suitable;

or

2) http://uk.rs-online.com/web/p/din-rail-panel-mount-power-supplies/0428477/

Thanks for any advice.
Jon

Is this for a replacement as they normally come in kits with every there for you?

Looks ok to me.

You could save a few quid by not using RS though.

PSUs can be had from your local wholesaler.

What does the manufacturer state? Obviously it needs to be 100% reliable in this case.

Hi LeeH,
I asked 3 local wholesalers to quote and the cheapest was Edmondson's at £54+VAT.

The manufacturer's specs are;
10A/30mA Circuit Breaker
24VDC/75W Class 1

Must be earthed.

And that is all it states.
Yes, it needs to be 100% reliable as this is hopefully a life saving piece of equipment. The local community centre have managed to raise the funding for 6 of these, to be installed on various buildings around the town. I doubt I will get to install all of them, but looking like I will have at least 3 to do.

Thanks
Jon

You can't guarantee that it won't ever fail.
If you want 100% reliability you might consider a dual redundant system. Two PSUs diode gated.
That would improve the odds. But it won't protect against mains failure, a lightning strike or other catastrophies.

The above would not be 100% reliable...i would say that the most reliable means would be a wind-up unit...and that,would probably get 98%

That's why I said it would improve the odds.
It would significantly increase the MTBF.

A town up the road,had one in their precinct which was stolen after 3 months

I have little time for those who would do this,and less,for those who would purchase a chorred item of medical equipment.

Me Bird has a shop, and the local First Responders have had a defib installed there.I don't know who did it, but it's not actually connected to power. We know this because a car went through the shop front, damaged the socket it was supposedley attached to, and there it was just coiled up. I've had to use a defib "in anger" with the RNLI, about 3 weeks after my Dad died from a heart attack,that's not a sympathy clamour, just the facts. Our Casualty, flickered several times, we had him actually beating, but he was on a boat, we got to him 30ish minutes after the shout, onn the beach helicopters, he didn't realistically have a huge chance, but we did manage to get a bit of life, though not enough. The practical in me says, " If we'd resussed, wou;d he have been happy?, No, alive but ----ed. My chest presses were "impressive", that';s from the Rescue 104 medic, not my other half.

chorred?

chorred?

Hi,it's Romanes for "stolen".

Romanes,is the Gypsy spoken language,derived in part,from Hindustani.

You will have used lots of these words,without knowing,such as "mush" or "moosh",for "man".

Growing up with,and around these folk,has given me more than several benefits

I should have guessed that from the context......
