Product Overview

The SPD3303C is a LED display screen programmable linear DC power supply that is both lightweight and feature-packed. It has three independent outputs: two sets of adjustable voltage and a fixed set of selectable voltages; 2.5V, 3.3V, and 5V. In addition, the ‘3303C has outputs that are short-circuit and overload protected. Total power is 220W. 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.

Product Characteristics

Design Features View more

Design Features

The SPD3303C exhibits high resolution, 10 mV / 10 mA, providing the user with excellent settability and read back accuracy. In addition, it maintains its ability to change output voltage or current in small increments while fully meeting the power requirements of the load.

Series/parallel/independent output modes View more

Series/parallel/independent output modes

Series-parallel function combines two power supplies into one and makes it very convenient for many applications. The 3303C has three independent outputs which can be controlled separately and also be turned on or off separately or at the same time.

Panel timing output functions View more

Panel timing output functions

Five output timing profiles are settable via the SDP3300’s front panel. Each profile is independent of the others and allows settable voltage and current values. The timer function allows for continuous output with profiles as long as 10,000 seconds / profile. In addition to easy front-panel control, the SPD3300 power supplies come with SIGLENT’s EASYPOWER PC software

Save/ Recall interface View more

Save/ Recall interface

The SPD3000C programmable linear DC power supply provides five groups of local storage system parameters and has support for external memory expansion. With this feature the local or external memory can be stored, recalled ,or deleted, making it easy to return to your desired settings.
