How do I choose a power supply for my bench?
Choosing The Right Bench Power Supply
- Parameters to be considered. Although many key power supply parameters will vary depending on each application, following parameters are critical in all cases:
- Resolution.
- Readback accuracy.
- Readback resolution.
- Stability.
- Temperature stability.
- Load regulation.
- Line regulation.
What is bench power supply?
A bench power supply provides DC (direct current) voltage to power a device under test such as a circuit board or electronic product. A bench or lab power supply typically sits on an engineer’s work area or bench, hence the term “bench power supply”.
What is bench top power supply?
A benchtop power supply is a tool for testing and measuring circuit systems by providing direct current (DC) voltage (power) to the device under validation. It’s typically used by electrical engineers, circuit designers, and other professionals in similar lines of work.
How do I choose a variable power supply?
Here is what you should consider when choosing adjustable DC power supply features:
- Linear output regulation.
- Multiple outputs.
- Control flexibility.
- Output enable/disable.
- PC control functions.
When should I use bench power supply?
Bench power supplies are extremely useful tools in testing circuits, as they allow you to adjust the voltage on the fly. If you have a project that needs a specific voltage or if you haven’t quite designed the power section yet, the bench power supply can be a life saver.
What should I look for in a DC power supply?
Some Basic Principles in Choosing Your DC power Supply
- Voltage Rating. If a device says it needs a particular voltage, then you have to assume it needs that voltage.
- Current Rating. Current is a bit different.
- Replacing Existing Supply.
- Advanced Concepts.
