You need power supplies in almost every project because the energy for your project has to come from somewhere. \ud83d\ude42<\/p>\n

There are a few things to consider. On the one hand, you don't want to put yourself (or others) in danger and on the other hand, you want the project to be built to be successful.<\/p>\n

It is particularly important that the power supply has enough power to supply the respective project. On the other hand, you don't want to have an expensive, huge power supply lying around at home. A compromise must be found between price, electrical performance and intended use.<\/p>\n

The criteria you should consider are described in the following article.<\/p>\n

The information contained on the data sheets of the power supplies is also described. Often you don't even have to buy a new power supply; you can simply continue to use the power supply from your old phone, children's toys, etc.<\/p>\n

Of course, you have to understand what voltage, current or power the potential power supply can deliver.<\/p>\n

Safety instructions <\/span><\/h2>\r\n

I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew "better" have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.<\/span>

sustainability<\/h2>\n

Ein Stichwort, dass man in den letzten Jahren immer \u00f6fter h\u00f6rt ist „Nachhaltigkeit“. Im Prinzip geht es dabei alte bereits vorhandenen Ressourcen f\u00fcr neue Zwecke zu nutzen. Genau dabei soll Euch das Wissen in diesem Artikel behilflich sein. Denn wenn Ihr die Symbole und Daten auf Euren bereits vorhandenen Netzteilen „entschl\u00fcsseln“ k\u00f6nnt, k\u00f6nnt Ihr diese auch f\u00fcr neue Projekte weiterverwenden.<\/p>\n

This means you don't have to buy as many power supplies, you don't have to throw away as many power supplies, and you also save money and other resources. \ud83d\ude42<\/p>\n

\n

Parameters of the required power supply<\/h2>\n

Voltage and voltage range (ripple)<\/h3>\n

The first important criterion of a power supply is the voltage. The voltage (formula symbol: U) is inevitably dictated by the circuit of your project. So you often need a certain voltage or a certain voltage range for your project.<\/p>\n

Habt Ihr zum Beispiel ein Projekt, dass \u00fcber einen USB Anschluss versorgt wird, wie zum Beispiel eines der Projekte hier auf Nerdiy.de, dann ben\u00f6tigt Ihr ein Netzteil mit einer „USB-typischen-Spannung“ also 5V+-0,25V.<\/p>\n

The voltage range of a normal USB power supply is standardized. This must always correspond to 5V with a tolerance of +-0.25V. The voltage that the USB power supply delivers is in the range of 4.75V-5.25V.<\/p>\n

Examples:<\/strong>
\n\u2013 Your circuit requires 12V: The power supply must also supply 12V
\n\u2013 Your circuit requires 5V: The power supply must also supply 5V. In this case you can also use a USB power supply \u2013 at least in terms of voltage.<\/p>\n

Electricity<\/h3>\n

In order to find out how much current (formula symbol: I) your power supply has to deliver, you first have to - at least roughly - determine how much power your circuit requires<\/strong>. Dabei ist es wichtig, dass Ihr nicht den „Normalfall“ annehmt. Also den durchschnittlichen Stromverbrauch. Sondern den Maximum case. <\/strong>Der Maximalfall ist in diesem Zusammenhang der Fall in dem alle Verbraucher den maximalen Strom „verbrauchen“.<\/p>\n

In order to determine the maximum current consumption of your circuit, you have to determine the maximum current consumption of all the components used in it and then add them up.<\/p>\n

You can always find out the maximum current consumption of a specific component from the respective data sheet or measure it with a measuring device. (But it is often easier to take the value from the data sheet.)<\/p>\n

Typical maximum current consumption:<\/strong>
\n1x RGB LED: 0.06A
\n1x normal\/simple LED: 0.02A
\n1x power LED: 0.3-0.7A
\n1x Wemos D1-Mini: 0.2A<\/p>\n

Examples:<\/strong>
\nWhatsApp lamp:<\/em>
\nThe WhatsApp lamp uses an LED strip with 23 RGB LEDs. A Wemos D1-Mini is also installed to control the LEDs. This means the maximum power consumption can be calculated as follows: 23\u00d70.06A+0.2A=1.58. So you should use a power supply that can deliver at least 1.6A. To be on the safe side, round this value roughly up to 2A. This way you are on the safe side.<\/p>\n

Instagram lamp:<\/em>
\nThe Instagram lamp uses two LED strips with a total of 35 LEDs. A Wemos D1-Mini is also installed to control the LEDs. This means the maximum power consumption can be calculated as follows: 35\u00d70.06A+0.2A=2.3A. So you should use a power supply that can deliver at least 2.3A. To be on the safe side, round this value roughly up to 2.5A. Even a 3A power supply would not be grossly oversized at this point. \ud83d\ude42
\n<\/span><\/p>\n

Performance<\/h3>\n

The power (formula symbol: P) is ultimately \u2013 in the track current range \u2013 just the product of voltage and current. However, on some power supplies sometimes the output current is not specified but only the output power. With this knowledge and the right formula, you can calculate what power or current your power supply must deliver. Because it applies:<\/p>\n

Power = Voltage * Current
\nrespectively
\nP = U * I<\/p>\n

Switching power supply or transformer power supply<\/h3>\n

The question of whether a switching power supply or a transformer power supply is actually not a real (technical) criterion that you have to consider when choosing your power supply. If the power supply delivers the required voltage and power, switching and transformer power supplies are electrically identical.<\/p>\n

The big pro argument for switching power supplies, on the other hand, is that they are often smaller\/more compact and also lighter than comparable transformer power supplies. This goes hand in hand with the price. Switching power supplies are often significantly cheaper than transformer power supplies, especially in the higher power range. But if you already have a transformer power supply lying around, you can of course use it.<\/p>\n

\n

Understanding data sheets<\/h2>\n

Every power supply now contains a data sheet that is either stuck on or stamped into the plastic of the housing. This data sheet always contains information about the permitted input voltage, output voltage, power and often other additional information.<\/p>\n

Unfortunately, these data sheets are often not uniform, which is why it is sometimes difficult to interpret these data sheets and understand the information. That's why a few power supplies and their data sheets with explanations are listed below. This should provide an explanation for every symbol or information. If not, just write it in the comment section. \ud83d\ude42<\/p>\n

General information about the information on the data sheets:<\/strong><\/p>\n

The information there is always maximum information. So if it says that a power supply can deliver 1A, then of course it can also deliver 0.2A or 0.5A. But not 1.1A.
\nThe same also applies to performance information. If the data sheet states that a power supply can deliver 50W of power, then - in most cases - it can of course also deliver 10W, 20W or 45W.<\/p>\n

Power supply of a printer<\/h3>\n

Below you can see the power supply of an old printer. This type of power supply has the advantage of being able to deliver different voltages and currents. The design is usually very specialized for the respective printer.<\/p>\n

\nIndicates (in combination with the underlying INPUT line) that the Input voltage<\/strong> (INPUT) in the range between 100V and 240V<\/strong> liegen muss. Dieser gro\u00dfe g\u00fcltige Eingangsspannungsbereich kommt daher, dass das Netzteil somit sowohl in Stromnetzen mit 120V (z.B. in Nordamerika, S\u00fcdamerika, etc.) aber auch 230V (z.B. in Europa, Russland) genutzt werden kann. Dies sind n\u00e4mlich die typischen Spannungen f\u00fcr die Stromnetze auf der Welt. Die Angabe „50\/60 Hz“ wei\u00dft zum einen darauf hin, dass die Eingangsspannung eine Wechselspannung sein sollte. Weiterhin gibt dies an, dass das Netzteil auch mit den verschiedenen Netzfrequenzen von 50Hz or 60Hz<\/strong> klar kommt. Die letzte Angabe „82VA“ gibt dazu an welche The maximum power the power supply absorbs<\/strong>. Normalerweise wird eine Leistung in Watt (Einheitenzeichen: W) angegeben.

Open\/closed frame power supplies<\/h2>\n

Open- or closed-frame power supplies are often delivered in the form of an open or closed metal frame. They are perfect for being installed in the housing of a device (e.g. monitor). Due to the very specialized application they often offer several functions (e.g. standby voltage or generally several voltages).<\/p>\n

Die Angabe „50\/60 Hz“ wei\u00dft zum einen darauf hin, dass die Eingangsspannung eine Wechselspannung sein sollte. Weiterhin gibt dies an, dass das Netzteil auch mit den verschiedenen Netzfrequenzen von 50Hz oder 60Hz klar kommt.

3. „CAUTION: For continued protection against risk of fire, replace only with exact type and ratings of fuse, 1,6A, 250V.“:<\/strong><\/em>
\nThis information indicates that there is a device fuse inside, which should be replaced with a new one with the information specified in the event of a defect.<\/p>\n

\n

Plug-in power supply with transformer<\/h2>\n

Plug-in power supplies are largely defined by the fact that the power supplies are integrated into the plug housing. There are plug-in power supplies with a transformer and plug-in power supplies as switching power supplies (see below). Plug-in power supplies with transformers are usually easy to recognize because of their relatively high weight. This is because these power supplies contain a transformer, which is usually very heavy. In addition, the housing shape is often almost cube-shaped.<\/p>\n

Da dieses Netzteil ein Transformator-Netzteil – und kein Schaltnetzteil wie die beiden vorangegangenen Netzteile ist – ist dessen Eingangsspannungsbereich limtiert auf einen festen Wert. Die Ausgangsspannung ist n\u00e4mlich direkt von der Eingangsspannung abh\u00e4ngig.\u00a0\u00a0<\/span>

Plug-in power supply as a switching power supply<\/h2>\n

Plug-in power supplies as switching power supplies are often much lighter and more compact than plug-in power supplies with a transformer. These also have the complete power supply technology integrated into the connector housing.
\nThe advantages over plug-in power supplies with a transformer are that they are cheaper, often more compact and lighter with the same performance and are also often suitable for different supply networks (which means that you can often simply continue to use this type of power supply when traveling to other countries).<\/p>\n
