What is the difference between a switching and linear power supply?
Linear power supplies deliver DC by passing the primary AC voltage through a transformer and then filtering it to remove the AC component. Switching power supplies feature higher efficiencies, lighter weight, longer hold up times, and the ability to handle wider input voltage ranges.
What if the amps are too high?
If an incorrect voltage is used — say a higher voltage than the device is rated to accept — then yes, too many amps may be drawn and the device can be damaged. This is why it’s critical to use the correct voltage.
What kind of power supply do I need for a benchtop?
There are many different options available but we recommend at least 2 channels for a benchtop supply, as it allows you to have 2 supplies going simultaneously (Think of all the 3.3V and 5V projects!). Each channel in your supply will have a resolution for both the current and voltage supplied.
What do I need in a Lab DC power supply?
Separate controls for voltage and current is a must on a lab DC power supply, and the voltage control should either be a multi-turn control or there should be a separate fine tune control. These controls should allow you to quickly set the output voltage to exactly the value required.
Which is the best DC power supply for home use?

How to choose features for an adjustable DC power supply?
Here is what you should consider when choosing adjustable DC power supply features: Watt for watt, switching supplies are smaller than linear supplies and offer more control features, but linear supplies are often a better choice for benchtop work.
