SPD3303X & SPD3303X-E Series Programmable DC Power Supply

description

Product Overview

Three isolated, independently controlled outputs live inside one 220 W chassis on the SPD3303X and SPD3303X-E: two adjustable 32 V/3.2 A channels alongside a fixed 2.5 V/3.3 V/5 V rail. The 4.3″ color display plots output waveforms as they happen, and switching between independent, series (to 60 V), and parallel (to 6.4 A) wiring modes lets one supply cover both dual-rail analog circuits and higher-current single-rail loads.

Frequently Asked Questions

1 How does the SPD3303X/X-E support debugging and testing of embedded systems?

The SPD3303X/X-E features three isolated outputs, including two adjustable 32V/3.2A channels, which can operate independently, in series (up to 60V), or in parallel (up to 6.4A). Its 4.3″ color display shows real-time output waveforms, aiding in monitoring and debugging. Additionally, it includes EasyPower PC software and LabVIEW drivers for remote control and automation.

2 What are the main differences between the SPD3303X and SPD3303X-E models?

The primary differences lie in their display resolution and accuracy. The SPD3303X offers 5-digit voltage and 4-digit current display with higher resolution (1 mV / 1 mA) and better accuracy (e.g., ±(0.03% + 10 mV) for voltage) compared to the SPD3303X-E, which has 4-digit voltage and 3-digit current display with 10 mV / 10 mA resolution.

3 Can the SPD3303X/X-E be controlled remotely or integrated into automated test environments?

Yes, the SPD3303X/X-E supports remote control through SCPI programming and offers timing/list functions for automated sequences. It also comes with EasyPower PC software and a LabVIEW driver, facilitating integration into various test and measurement setups.

4 What are the maximum voltage and current capabilities when using the series and parallel modes?

When operating in series mode, the SPD3303X/X-E can achieve a maximum output voltage of 60 V. In parallel mode, it can deliver a maximum current of 6.4 A. The two adjustable channels each provide up to 32 V / 3.2 A independently.
