  • 100/120/220/230 V compatible design, to meet the needs of various power grids

Product Overview

The SIGLENT SPD3303C Programmable DC Power Supply is a LED display screen and programmable linear DC power supply that is both lightweight and feature-packed. It has three independent outputs: two sets of adjustable voltage / current and a fixed set of selectable voltages; 2.5, 3.3, and 5 V. In addition, the SPD3303C DC power supply has outputs that are short-circuit and overload protected. Total power is 220 W. It has three available operation modes; independent, series and parallel modes. The SPD3300C has a high performance-to-price ratio and can be used in various types of production, education and research environments.
