Why do you need a bench power supply?
A bench power supply is a really practical tool when it comes to circuits. It allows you to power your circuits before they are finished, to test individual circuits, to experiment, etc.
This way, you don’t need to have a specific power supply for each project you want to test. It makes your life simpler, allows you to test your ideas much quicker, and provides a reliable source of power at different voltages.
Fortunately, nowadays, simple bench DC power supplies aren’t that expensive anymore, and you can even build your own (which we don’t recommend if you’re a beginner).

What to look for in a bench power supply?
Let’s take a look at the features you should take into account, before picking up the best bench power supply for your needs:
Maximum voltage and current
It is important to know how much voltage and current the bench power supply can provide, and if is able to power up most of your projects. If you’re supplying your circuit with some voltage, the power supply must be able to keep up with the current drawn. You should look for the bench DC power supply power envelope, that shows the possible current values it can draw at different voltages.
Current Limiting Control
Current limiting control is a great feature, specially if you are a beginner. This features allows you to set a safe current limit to protect your components.
Number of channels
In many cases, using a single output channel does the job, and it is more affordable. Power supplies with multiple outputs are more expensive, but can be handy in cases you need different supplies simultaneously.
Linear vs switching
Power supplies are available in switch-mode (switching) or linear designs. The difference between them is how they produce DC power. Each one has advantages and disadvantages, but in general switching power supplies tend to be lighter and more compact. On the other side, linear power supplies are better suited for powering sensitive analog circuitry because they have lower electrical noise.
Bench Power Supplies Comparison
This is a simple power supply with one channel that can supply voltage up to 18V and current up to 3A. It is linear, providing a super stable output and low ripple. You can adjust the voltage and current with the two rotary switches, and turn it on and off using the button switch at the front. The package also comes with two power cord test leads with alligator clips.
This is a very good power supply accordingly to the comments on amazon. The only drawback is that the adjustment of the rotary switches is very sensitive, and sometimes it can be difficult to dial the exact voltage you want.
This power supply from Eventek is also a great choice for hobbyists . It is compact, and can provide 0 to 30V and 0 to 5A with an accuracy of 0.1V and 0.01A. There are four rotary switches, two for coarse adjustment, and other two for fine adjustment.
It can operate in constant voltage and constant current mode. It is equipped with limit current protection, thermal protection, voltage overload protection, and short circuit protection. The package also comes with test leads.
This power supply is similar to the previous one but can provide up to 30V and up to 10A. This is perfect if you intend to work in a higher range of current.
This bench DC power supply from Circuits Specialists can provide up to 30V and 5A. Its features include: linear mode, coarse and fine adjustment, button lock function, and can operate in constant voltage or constant current. It also allows to set current limiting or voltage limiting control. This is definitely a great choice for a beginner or hobbyist.
This bench power supply is very similar to the previous one providing up to 30V and up to 5V. One additional feature of this power supply that can be really handy is the 5V DC fixed output on the rear panel, which can be very versatile in some projects.

In this post we’ve shown you the best bench power supply for electronics hobbyists. All the power supplies presented are very good choices. However, the perfect power supply for you will depend on your needs, and how much you are willing to spend.
If you are on a lower budget and the operating range of 0 to 18 volts and 0 to 3 amps is suitable for you, then pick the Tekpower TP1803D.
Finally, if you need a wider operating range, then go for the Eventek KPS3010D, which can provide up to 30V and 10A.
We hope you’ve found this list useful. Thanks for reading.
