DC Power

DC Power

Our innovative DC power supply category features devices for R&D, design, quality control and production. Multiple output power supplies have more than one DC output and are used for systems needing multiple voltages. Triple-output devices are commonly used during circuit development. Constant voltage/current devices, such as the G-Series by Instek, provide regulated output across varying loads. Our versatile selection of power supplies provides programmable, computer-operated models from a number of leading manufacturers, including B&K Precision. We also offer many models from Keysight Technologies with purer power, reliable regulation and fast transient responses.  Be sure to check out Rigol power supplies for high performance and affordable entry-level models.


Buying a DC Power Source


Many power supplies are designed to have AC power as input and DC voltage as output. When searching for a DC power source, you will need to determine if you want switching or linear regulation to perform the power conversion. Models with a switching regulator are characterized by higher efficiencies. Linear regulator models provide lower noise and ripple levels. Specifications to consider include:


  • Output voltage and current
  • Input voltage
  • Load and line regulation
  • Ripple and noise
  • Constant voltage and current modes
  • Transient response
  • Interfaces and overage protection


The Most Popular DC Power Supplies


The Keysight Technologies 6030 Series features an electronic power supply that’s ready to do the job of several devices. Its auto-ranging output means maximum power is supplied at various operational voltages. The N5700 Series from Keysight comes in a compact package with stable power, plus built-in voltage and current measurement. B&K Precision’s 8500 series allows you to perform precision programming or front-panel parameter control. Rigol’s DP800 Series, including the very popular Rigol DP832 is a triple-output DC supply featuring low ripple/noise with superior load and linear regulation.
