PSU for your Spectrum

Hello, Scorpion(lv)
Sco> You can use the DS then the DS converter during the course of the truth in this case
Sco> 24 but no open elements can be sourced from the battery
Sco> solar battery and just a transformer with a bridge In the picture
Sco> converter 5 volts to 4 amperes size 50x50x7.5 mm By the way, it worked
Sco> the board in the sea powered a small computer from a battery that
Sco> charged from solar panels
As a power supply I use some kind of UPS from a printer or something: v2_conf3; exit; 12th century
plus this DC-DC converter :cool; entrance; 9-30 volts, 5 V output up to 3 amps,
efficiency 90%.
PS I’ll tell you a secret, this miniature converter was absolutely taken from the Internet
free :smile;

Hello new art
You can use a DS or DS converter during the course, although in this case 24 V but
no open elements, source can be battery, solar battery and
just a transformer with a bridge In the picture there is a converter 5 volt to 4 ampere size
50x50x7.5 mm By the way, this board worked in the sea and powered a small computer from
battery that was charged from solar panels

Hello, CheburatoR

Looks like this: http://daloafhouse.narod.ru/p1024sl/power.jpg
(there is a transformer at the input, it seems from some kind of reel-to-reel “Nota” :))
But +12V: http://daloafhouse.narod.ru/p1024sl/12V.jpg
Hello, m.d.
The power supplies were different...
but only 2 remain in memory.
1. Power supply from my first Spectrum type Krasnodar-48
transformer, with a bridge rectifier, heated up like an iron, reacted to
refrigerator . had a techno design
2. Products shown in the center in the photo newart
the rate of their failure and the burning of the cell boards actually connected to them
caused negativity.
3. now only power supplies from PCs or similar equipment...
Hello Orionsoft
Ori> The power supplies were different...
Ori> but only 2 remain in memory.
A friend recently got a pulse power supply left over from my old one.
Pentagon128. Stuck it in Scorpio. The power supply had +5v, +12v, GND.
I usually use AT power supplies from the trash heap with excess parts thrown away (i.e.
fee only) - fans and other things go to the garden.
Hello, CHRV
All sorts of power supplies I didn’t have... Now for setting up and launching the boards
Pentagon-1024SL I use the industrial power supply "Electronics MS 9016", and as
regular - AT/ATX.

By the way, does anyone have a circuit from the above-mentioned MS 9016? Yes, for the sake of
interest. I have 2 of them, but no documentation other than instructions,
no.
Hello KingOfEvil
My PC power supply without a fan worked for 5 years and didn’t get hot, fortunately
the speck doesn't need much.
Hello new art
new> All except the last one came complete with scorpions. All power supplies are different
new> which suggests that even 1 clone does not have a standard for power supply.
They sent me a completely different power supply from Scorpio.
Pulse, small but powerful, I think 70 watts. Easily pulled scorpion and 2
5"25 disc converter. And very high quality made for that period of time (1995)
It has a sticker on it that says it was made in St. Petersburg.
In general, I’ve used different ones all the time. Now, of course, it’s easier to use special ones.
Hello Costa
As a power supply for my Scorpion ZS 256 I use a pulse power supply from the Poisk PC.
Hello deathsoft
dea> As a power supply for my Scorpion ZS 256 I use a switching power supply from
dea> PC "Search".
During the time of Leningrad-1 (Zonovsky) expanded to 128 kb + betadisc + 2
Tikovsky flops of 720 kb + 1 flop 3.5 - used then
popular, reliable, but quite expensive for those times, an impulse generator from
SEARCH.
BEFORE this there was a circuit using transistors and cranks. The total area of the radiator is
It was probably the size of a cider. The transformer was homemade and weighed heavily
2 kilograms.... :v2_jawdr; :v2_tong2:;
Then some cases like the current SLIM appeared in St. Petersburg - from the telephone
Erickson station - there was a built-in impulse, equal in power to Search.
Now I’ve tried all sorts of options from PeTse - from modest 145 padded jackets to slims to
server power supplies from bigtowers.
At the moment it costs 400 W ATX, with it throttled almost to a complete stop
fan (temperature at scorp load + all my bells and whistles) is equal to
room
Hello, Kir
Kir> there are 4 pins
in the center there are two common ones, on the left +5, on the right +12 (or vice versa)
Hello, Mikka_A
Got Byte-48. Does anyone have a power supply diagram for it (there are 4
output). I would be very grateful :)
