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.
