DC Power Supplies

Matching the Bench Power Supply to the Application

Whether being used to train the next generation of electrical engineers or for developing a breakthrough in ultra-low power, wearable products, bench power supplies must meet a wide range of power sourcing requirements.

For applications ranging from basic power sourcing to those that push the limits of performance with high sensitivity sources or sources that can deliver thousands of volts, using the appropriate power supply is critical to obtaining successful test results in teaching, research, design and manufacturing.

  • The most common selection criteria are:
  • Output voltage, current, and power
  • Setting resolution and accuracy
  • Ripple and noise
  • Features and programmability
