Why are bench power supplies so expensive?

Why are bench power supplies so expensive?

What part or parts are making these machines to expensive? They generally have multiple outputs. They have parts to make the multiple output voltages variable. They have parts to control the output current for the multiple outputs.

How do you make a power supply?

To build this specific power supply, you will need the following:

  1. Power cord.
  2. SPST 120V toggle switch.
  3. Panel mount 120V neon lamp.
  4. 3 binding posts.
  5. Transformer with an input voltage of 120V and an output voltage around 24V to keep the Vin for the 7812 regulator above the minimum.
  6. Full-wave bridge rectifier.

Why should we get bench power supply?

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.
