If you have also recently been looking for a suitable resource for amateur equipment, so i can recommend this one:
It doesn't hum, it is said to have short-circuit protection (I did not test) and after putting it in this box, I think it is quite satisfactory:
https://www.profimax.sk/suciastky/plastovy-program-krabicky/krabicky/krabicka-k6-montazna-s-potlacou
I have the 12.5A version…
Do not experiment with the source, I have a DM-330MV – ALINCO. does not hum, does not make noise and reliably gives maximum performance for a long time
I ask someone for advice

Closing the source where it is assumed that the type of cooling in a plastic box is a great idea 😉 Check the height of the damage insurance.
The power source is 150W, I estimate the effectiveness at approx 80% at half load, do not release the nut, the box must melt already at 5A permanent draw 🙂I don't know, but 12×5 i 60W, if there is efficiency 80%, as you say, so 12W won't dissolve the box, but I will put holes or a small vent there.
I mean, that exposed 220V contacts can be even more dangerous, especially for my child.
You mean, that if he could, so the tin on the tin box won't save?
Another thing is the lifetime of the components, mainly elites.Electrolytes can be replaced, they are not expensive. The vitality of everything is today, it appears, five minutes, if we exaggerate a bit.
I understand the affinity for quality, but I wanted to recommend something affordable for everyone. Source, which Stefan recommends is definitely ok, but this price!
But the price of TRCV 🙂 TS-480 saved me after a lightning strike somewhere very close ( the antenna was attached ) and the repair of the source was only sent for 20e 🙂
I either drive a Mercedes or a Tic… it's up to you … It would help me a lot

The comment was not about the quality of the elites, ale to that, that increased temperature in a closed box means a faster end of the elite.
Another thing is safety, fire or detonation of the radio due to a malfunction in such an unnecessarily closed source. The source is not a place, where it pays to save at any price.Ako dokazes zakryt kontakty 220V?

Friend, try to study something about the basics of protection against the effects of electric current. One fine day we could lose your unique contributions. Electricity is a good servant, but bad master. Better to buy a ready-made factory-made power supply with certification and avoid experimenting with voltages higher than 12V.
(OK2VFS)There is a good source in our market (I use two) from QJE type PS-30SWI for 67 in euro. My experience: does not disturb, can give 25A continuously, is small. That's it 1,5 I changed the fan last year – he became noisy. Max. satisfaction. Do not take this as an advertisement, just sharing my experience.
Hi Norko, people are mean to you, but don't do anything about it. The mistake is in it, that he asked the wrong question. The relevant standard knows several possibilities. One of them is location protection. I.e, that if you put the contacts in height 3 meters, so it's basically good. But to be sure, it is good to put this device in an iron cage and ground it well. And for peace of mind, you should call an inspection technician, who will revise your device and if you have complied with the standard, so he'll give you an audit report,, which entitles you to use this device reliably and safely.
Dusan, people are not only mean to me.
I put the source in that plastic box, navrtal zo 12 holes and everything is ok.
Yet. The future is not ok for anyone. Not even for electric shock protection experts.Once, as an honest soul, I had my modem homologated. A technician arrived, he looked at the modem and the socket, He issued me a bill for SKK 800 and left.
P.S.: We were there Cechach mate at the studio complex, or what….you should study it.

For example, this is how OM0ODB is handled: https://sites.google.com/site/om1aeg/prevadzac-om0odb
The problem is, that on the basis of the price you are trying to use a thing intended for powering lamps for powering trx. When powering the lamps, a fixed installation is considered, often out of reach “laymen” and it should be installed by a person with minimal par. 21 and finally, Mr. Par should check it. 24 It would help me a lot
Things like a doer, effectiveness, reliability, immunity to induced vf from trx and antenna, rfi, protections are about “foreign words”.
Properly induced vf from tx with an unadapted antenna using source wires as part of the antenna is quiet “continue” some snz from 13V to 19V with relevant consequences for the trx 😉
That source in that operator looks similar to mine, only it is not in a plastic box.
I can't see it well, but it looks, that it is protected by zeroing?
But I don't have the possibility to place it on top of Kamzika, so that no one can reach him.
It's funny, that some sources designed to power the trx are humming and mine is not.I don't really like the solution in the box, but still no one said, how cleverly cover those contacts and probably won't even tell.
Tone, if I cover it with sheet metal and the phase conductor accidentally comes loose (is under the screw) and touches the plate, who takes responsibility for any death in the family.
This also applies to the solution of the Czech amateur, see. higher.
