Power supply EMACS M1R-2500G.

Kilowatt and cheaper

For my modest radio destructive needs, the question arose of acquiring power supplies for running 12V and 24V, but more powerful, so that it would be possible to power not only the T12 soldering station, the step-down converter module, the backlight, … and so on and so forth. Even more compact.
In general, searches brought me to the pages of a store that sells mainly second-hand server hardware and inspired me to do a little home-made. For details, please under the cut! nine0101
Alas, there will be no detailed testing and research for lack of skills and equipment. Mr. Kiric spoiled the audience)

So. While looking for a PSU, I came across solid 12V 500W power supplies from storage systems — Hot swap EMACS M1R-2500G for ridiculous money for units of this class. Of course, they are BU (from the gutting of some old server), but still this is server hardware designed for long-term and stable operation. There are also high-quality components (at least in comparison with Chinese blocks), APFC, at least there must be protection (short circuit, overvoltage …). nine0005

In truth, I have not seen even frank trash on Ali at such a price. So, without hesitation, an order for 2 blocks is placed, money disappears from the card, and waiting for the order …

About delivery, or friends in need are known

Usually you can’t tell anything interesting about delivery — whether it came or not. But then there was a small incident.
Shipping — boxberry. Less than a week of waiting, joyful gutting of the parcel — and here is the nuance … Blokov ordered two, and one came! Yes, exactly the one that I ordered, but the worker … but one! On the one hand, it seems like they threw it, but on the other hand, it seems not. nine0101
Mixed feelings overcame me at the time. But I pulled myself together and went politely to find out what was the matter. To the credit of the guys from Khlamada, I can say that there were no debates — I showed a photo of the parcel, into which only one block wrapped in bubble wrap could hardly fit, and they sent the second block at their own expense.
And this is without any Aliexpress and at least somehow a working system of disputes / returns. Reputation is important to people, in my opinion.

For connoisseurs of dismemberment — the insides of BP

Here it is, Sweet couple:

Dismantling of the case — unscrew only 6 screws:

Bottom view:

Closer output part + how to start the PSU:

And now about the idea and implementation.
Having two switching power supplies, you can safely connect them in series and get an output voltage equal to the sum of the voltages and a maximum current equal to the minimum current that one of a pair of power supplies is capable of delivering. Pattern:

You can read more in this article, or there is an excellent review of on the same topic.

In such a connection scheme, nothing prevents you from taking power directly from the first PSU — that’s 12V without any converters. But we must not forget to summarize the current load both through the first (12V) and through both (24V), so as not to exceed the maximum allowable.

I won’t tell you the exact dimensions of the blocks without a case, but for their joint work + active cooling thin (no more than 15mm thick) 9According to estimates, a Gainta G3118 plastic case (not advertising — just a link to the manufacturer and model) with dimensions of 240x120x60mm came up with a 2mm fan. In general, overall cases are much cheaper to buy from us, and delivery is faster. At the time of purchase cost about 700r together with delivery. But now the prices have changed — so only the search.

According to the PSU data, I want to note a useful nuance — there are no protections associated with the operation of the cooler. Blocks start without it. So you can get by with only one thing — after all, the blocks are now not in narrow cases and blowing not through all very densely located components from the end, but from above. So there is no need for high-speed coolers. nine0005

Trying on:

This was followed by cruel abuse of the case — drilling and cutting holes for the input connector and switch, for the cooler, ventilation holes, holes for the XT-60 output connectors and PSU LED indicators, pasting M2 racks:

PSU modifications were reduced to desoldering the output connectors assembled on a plywood frame and desoldering anti-parallel diodes:

Minus the PSU and the filter outputs to the ground were connected through the native case and racks. Now the case is plastic and there is no need to separate the minus from the ground by 2m PSU. But I had to solder the ground connection with wires. Now I think, maybe it was worth cutting out the bases of native buildings and pasting them to the bottom of the current building .
