Programmable Linear DC Power Supply
Feature
The SK33XX series programmable linear DC power supplies have three independent outputs – two sets of adjustable voltage/current and a fixed set of selectable voltage1.8V, 2.5V, 3.3V and 5V. it has three available operation modes–independent, series and parallel modes. All make this series become a high performance-to-price ratio instrument.
