Buying Guide: Things To Consider When Select Benchtop Power Supply

Let’s have a look at some of the things you should consider before making a purchase:

a) Maximum voltage and current

Knowing how much voltage and current the bench power source can deliver, and if it can power most of your projects, is critical. Power supplies must be capable of delivering the current drawn by the circuit when providing voltage. It’s important to check the bench DC power supply’s output power. Using this, you can see how much power it can draw at various voltages.

b) Current Limiting Control

If you’re a newbie, the current limiting control is a fantastic feature. Using this tool, you can set a safe current limit that will protect your components.

c) Number of channels

Using a single output channel often suffices, and it’s also less expensive. Multi-output power supplies are more expensive, but they come in handy when you require several distinct power sources at the same time.

d) Switching vs. linear

Switch-mode (switching) and linear power supply are offered. DC power generation is the main difference between the two. Switching power supplies, in general, are lighter and more compact than non-switching power sources. To power analog circuitry that requires minimal electrical noise, linear power supply are better suited.

Final Thoughts

For electronics amateurs, we’ve compiled a list of the top bench power supply. We recommend any of the power supplies listed. It’s up to you to decide which power source is best for you based on your needs and your budget.

The Tekpower TP1803D is a good choice if your operating range is limited to 0 to 18 volts and 0 to 3 amps. With that in mind, if you’re looking for something with a larger operating voltage range, the Eventek KPS3010D is the best option. We hope this list was helpful to you. It was a pleasure to meet you.
