Special ATX PSU power supply tester PST-64

Description

Warning!
This device was manufactured in a limited number of 20 pieces.
At the time of writing, just a few devices remain.
Therefore, it may not have a flawless aesthetic appearance, because it is not a product produced in thousands of pieces, but in terms of functionality it has no competition. The main aesthetic disadvantage is that the top foil has openings offset from the openings of the device box by about 1 mm
(see the last photo)
. However, this is only a small aesthetic shortcoming. I also do not know the properties and durability of the adhesive with which the top foil is glued to the box. The selling price is much lower than the costs of developing and manufacturing the device.
The device is fully functional and reliable. I made it to serve flawlessly for many years. In view of these facts, keep in mind that this is not a large series production and please, accept small aesthetic imperfections.
The device was developed and made by a hobby manufacturer, so the manufacturer cannot provide an invoice !
Special ATX power supply tester
PST-64
A unique tester in this category
The PST-64 tester is intended for real, precise and professional testing of ATX power supplies. It provides an overview of all important qualities and values of the unit. PST-64 allows monitoring of voltage without loads in real time, monitoring of voltage fluctuation (Ripple), as well as noise (Noise), the latter an indicator of damaged filtration condensator or damage dealt to the electrical circuit of the power supply. Aside from the load monitoring function, the tester also contains a one-off test mode. In this mode, the device tests the source with resistor loads of a power output of up to 120W, allowing it to examine the source even more thoroughly. A very important indicator of the measured
power supply’s condition is it's calculated rough estimate of maximum output power
. The results of such a test can be saved in the internal memory of the device. It is possible to store data records from four different measurements in the memory. The device also includes the „Self-test,“ function, in which the user can verify the functionality of the tester and it's potential basic errors, which could cause imprecise measurements. The tester has a standard power input from the measured power supply. However, in the „Self-test“ mode, the tester needs to be connected to the power grid via an independent 230V AC,50Hz/5V DC power adapter, provided as a part of the set.
The device was developed by hobby electronics (Dumarch) within four years of development, research and plenty of measurements and calculations.
All components are industrially manufactured.
This device is available only from Dumarch.com, where you can get more information. On Ebay from
Dumason.
PST-64 is only one device this quality in the world and will be assembled only in a few pieces - limited edition.
Don't compare this tester to classical cheap testers, available everywhere.
Notice !
Power adapter 100....240V AC/50...60Hz input to 5V DC/1A output.
Output terminal 5V DC: 5,5/2,1
Power adapter input terminal is type EU !!!
If you use a defferent terminal, you will have to add a proper reduction!
