DC Power Supply
Matching the DC Power Supplies to the Application
DC power supplies are used for a wide range of applications from training the next generation of electrical engineers to developing breakthrough ultra-low power, wearable products. Whether you need a DC power supply that provides basic power sourcing or one that pushes the limits of performance by delivering thousands of volts, choosing the appropriate variable bench power supply is critical to obtaining successful test results in teaching, research, design, and manufacturing.
How to Choose the Best DC Power Supply
The most common selection criteria are:
- Number of output channels (single or multi output)
- Output voltage, current, and power
- Setting resolution and accuracy
- Ripple and noise
- Features and programmability
- Advanced features like current measurement with nanoamp resolution, sequencing, analog inputs, digital I/O, and programming features
