I’ll write right away, the article is divided into two parts.
First part
Initial creation of the stand, calculation of space, equipment, search for the necessary spare parts and devices.
(Start of work: 08.11.21009. End of work: beginning of April 2010)
And the second part is the completion of the 6th section in 2018
+ minor improvements to the remaining sections.
I did not think for a long time on the name - SUZU-5T
SUZU is a Stationary Universal Charger.
5T is the number of transformers used in the stand.
The first section:
TR-1: primary-220v, secondary: 3v-0-3v / 6v / 12v / 18v-0-18v / 36v
the transformer was pulled out of some kind of stationary sound prefix from the times of the USSR.
Voltage selection is done by connecting jumpers between the terminals.
The selection of voltages takes place on a variable circuit, and only then a diode bridge goes.
The trance itself is very weak, and is only suitable for testing different bulbs, engines and other electronics with a consumption of no more than 1-2 amperes.
Second section:
TR-2: 220v / 14v controlled voltage.
I don’t remember the toroidal transformer where I came from, but it was his appearance that provoked the idea of such a healthy stand. Because initially there was only trance used in the third section. And some little thing. And one trance was not enough to start creating a stand. The transformer has enough amperes for 10 easily, but I try not to load more than 5 amperes, because I’m not sure of the reliability of the diodes in the bridge for a long time.
The adjustment is made by a PPB-15 potentiometer, which opens the thyristor. The diode bridge is assembled on computer radiators, a fan is also used for cooling.
Third section
TP3 - power transformer OSM-1 220/12, diode bridge on coolers with a fan.
Also on the panel of the 3rd section there is a cigarette lighter plug and an internal cooling switch.
Cooling involves through air blowing through the entire interior of the stand. So that the temperature does not rise inside.
Fourth Section:
TP4 - a conventional low-current power supply for 12v.
TP5 is a conventional low-current 9v power supply.
This section also includes a switching power supply from the computer. output: 12v and 5v.
Sixth section:
Left in reserve. Until the appointment for her is not invented.
It was planned to put a sound amplifier for the computer there, according to the shallow idea, because of a bunch of pickups from transformers. And then I assembled a separate deck with an amplifier on the radio.
Then I wanted to place a compressor control panel with pressure gauges there, but the compressor is still not ready and drag the route far away.
I also wanted to build in several measuring instruments there, but there are three multimeters and they are still more than fulfilling their duties.
I apologize that the photos are going in the wrong order, as part of adding materials to the site I did not find the opportunity to post correctly according to the chronology and purpose, so everything is mixed up (((
The second part of the project. Modernization.
There are really no photos already, but there is a video review with the 6th section.
So, what modernizations were made at the time of shooting the video, and what was done later.
The first section, just added a small digital voltage indicator.
Second section:
The toroid burned out a couple of years later))) The usual one of similar power was supplied, enough for 10 amps at maximum, but we don’t load more than 5 amperes.
+ Added a small digital voltage indicator.
The third section by purpose and contents has not changed, but on the front panel in the third section there is a USB connector (powered from the 4th section) for charging phones and other gadgets.
A small digital voltage indicator was added.
Fourth Section:
TP4 - TP5 - pulse power supply, everything remains unchanged. Only from this section has power supply for the illumination of the upper shelf above the stand, with white and RGB ribbons, been made.
The fifth section is 220 volts, a small SKLka after the video was recorded was replaced with a round mortise digital ammeter with a shunt.
Sixth section:
220V through a dimmer.
SKL 1 - signals the presence of voltage on the stand.
SKL 2 - the presence of voltage at the terminals of the 6th section.
SCR 3 - voltage after the dimmer.
Then replaced the third SKLK with a digital voltmeter.
In the future I plan to replace the 6th section dimmer with a more adequate one.
And you need to make a normal adjustment in the 2nd section. There, the control circuit, which just occurred to me without any calculations, stupidly some kind of power pole is taken, and fed to the thyristor control through two resistors connected in series, constant and variable.
One could still write a lot of things, what types of shunts and devices were used, which terminals and wires are where, but I do not see any sense in this. The idea and principle seem to be clear and so.
on the description and photos of the stand during its creation (2009-2012).
Also there is a video with the first tests of the stand.
A video review of the stand was recorded back in January 2018, so not all alterations in it are displayed:
