Bench power supplies are versatile components that can be used at various stages of electronic projects. We recommend them as a helpful tool during prototyping and calibration during the assembly of electronic devices. Moreover, they prove themselves in the repair of electronic devices and tests of already finished projects. Bench power supplies are distinguished by a unique, special design, which allows you to adjust the power supply parameters in a given moment, in real time. They are especially recommended for projects characterized by non-standard power supply voltage. Then, using a bench power supply unit, we will design a power supply section. Bench power supplies in our offer are available in many variants. We recommend them to people who deal with designing and creating electronic systems and all kinds of devices, as well as their repairs. They will also be a perfect complement to scientific aids in schools and universities, where there are scientific and didactic laboratories. They will definitely increase the possibilities of education.

Use of bench power supply
Bench power supplies perform a very important function. They are a source of power supply. They enable adjustment of its output parameters, which makes them a universal power source and can be used with many different devices. Their versatility is also manifested by their use at various stages, both in design, assembly and during service and numerous tests. Having a bench power supply, we do not need to have several single-voltage power supplies, which differ significantly in output parameters. Such devices do not create the possibility of regulation. In the case of a bench power supply unit, we can quickly and easily set it as a DC source depending on current needs. The parameters are read on digital segment displays.
The bench power supply should therefore be included in the equipment of every DIY enthusiast, electronics, electrician and robotic. It will help in many advanced projects, as well as enable improvement of those already created. It eliminates the need to have many power supplies, differing in constant voltage.
Selection criteria for bench power supply
Bench power supplies differ in many parameters, which play a key role in choosing the right one. We always have to take into account the maximum output parameters of the power supply, i.e. current and voltage. They are responsible for the smooth start-up of each project. It is important to be able to independently and smoothly adjust the output parameters, which include voltage and current capacity. Due to the built-in output current regulation we can manually set the current capacity limit. This is related to safety, because it maximally reduces the risk of damage to the components of which the electronic system is built. Bench power supplies should also have other protections, including short-circuit, over-voltage and overload protection. Multi-channel power supplies are indispensable in many complex projects. They should be used wherever different supply voltage values are required.
An interesting option in bench power supplies is the function of storing input parameters in memory. It is useful at the moment when we make several identical electronic devices. We can also distinguish between impulse and linear bench power supplies. They differ in the way the AC voltage is converted into DC voltage. Impulse power supplies are small in size and weight. Linear power supplies, on the other hand, with a transformer and linear voltage stabilizer are irreplaceable when supplying analog systems, which are poorly resistant to voltage changes. This is due to their specific design. The presence of a digital segment display is of great importance for the comfort of operation. It allows for quick, easy and precise reading of all output parameters.
