Power supplies are devices whose task is to match the available voltage to the requirements of the equipment being powered. There are many possibilities to change the size of the voltage, which allows to distinguish several basic types of power supplies. Among them there are linear, pulsed and stabilized power supplies. Many power supplies have a parameter adjustment function, so they can be adjusted to the specific equipment and used with more than one. These are universal power supplies with wide application. When it comes to power supplies, which are characterized by current parameter control, they are used mainly in laboratories. There they are used for prototyping. In domestic devices, in turn, socket power supplies are commonly used. If we are looking for a power supply for a LED strip, the best choice will be a mounting power supply. All these models are available in Botland shops. We offer a wide range of products, among which are car, emergency and industrial power supplies, as well as power strips and water generators.

Power supply in different versions. Explore the types of power supplies
Power supplies differ in their parameters and thus in their purpose. A different model is used in domestic applications and another in industrial and laboratory applications. The power supplies are used by electronics and robotics fans, who create new systems and devices, as well as prototype. They are essential elements in the construction of any device that needs power. They are useful during repairs and calibration. The most universal ones include laboratory power supplies, but functional generators are similarly used. They are distinguished by their great ability to generate current courses with a specific function shape, including sinusoidal and rectangular. They are used in circuit testing and scientific research, so you can find them at technical universities.
There are also socket outlets for a specific device. We will easily plug them into a wall socket and the right plug into the equipment. If we decide on this variant, we must pay attention to voltage and current. We also remember to check the plug at the end of the cables. Power supplies of this type work well with development boards.
Particularly interesting are the mounting power supplies, which are dedicated to LED strips. Currently, they are very popular because the strips are perfect for decorative and additional lighting, such as furniture or stairs. Universal use is characterized by power supplies for DIN rail, which can be found in home, office and industrial space. If you are looking for a good power supply for equipment that is damaged due to unexpected power outages or changes in specific parameters, choose a UPS. It is used, among others, in desktop computers. For the same equipment, we will use an ATX power supply to provide it with voltage of different parameters.
Power supply accessories
We offer not only various types of power supplies that you can use at home, in the office, industry, university and laboratory, but also necessary and useful accessories for them. These include cables and adapters of various lengths. In addition, we recommend extensions and power strips designed to control more connected devices. For energy recovery, use a power generator. A car power supply unit with one or more USB ports can also be a useful accessory.
Check out our range of power supplies, which are available in the shop in many variants. We encourage you to check the laboratory power supplies, emergency power supplies, socket outlets and assembly power supplies. We also have power supplies for rail and ATX power supplies. To increase the possibility of their use, we have supplemented our offer with cables and adapters, extensions and power strips, as well as power generators and additionally car power supplies.
