SPD3303X Programmable DC Power Supply

The Siglent SPD3303X is a programmable DC power supply designed for use in electronics testing and development. It features three independent output channels—two adjustable channels offering up to 32 V and 3.2 A, and one fixed channel with selectable voltages of 2.5 V, 3.3 V, or 5 V. With a total output power of 220 W, the SPD3303X supports multiple output modes including independent, series, and parallel configurations, making it suitable for a wide range of applications. Its 4.3-inch color LCD provides clear, real-time waveform displays and detailed voltage/current readouts. The unit also includes advanced features like timing output programming, overvoltage and overcurrent protection, and remote control via SCPI commands or PC software. These capabilities make it an excellent choice for R&D labs, educational environments, and production testing setups.

Series / Parallel / Independent Mode Function

Series and parallel functions allow for combining two channels into one output with more power output capability, extending the application range. Each of 3 channels power can be turned on or off independently and also can be turned all on or all off.

High-Resolution and High-Precision Output

The highest resolution of 1mV/1mA(SPD3303X), provides excellent setting and read back accuracy. This ensures accurate output even with very with small changes in voltage or current. This is impossible for a low resolution power supply.

Panel Displays the Timing Output

Using the front panel, users can view and manage up to five groups of timing and output settings, offering a straightforward way to program power delivery. Additionally, the unit supports connectivity with Siglent’s EasyPower PC software, enabling comprehensive communication and remote control capabilities.

Save / Recall Setting Parameters / PC Timer

SPD3000X series programmable power supply can save or recall 5 groups of setting parameter in internal storage, also supports external storage expansion. You can easily obtain the settings you needed.

The SPD3000X / X-E Series DC Power Supplies

SPD3000X / X-E Series Linear Programmable DC Power Supply supports programmability and real-time wave display, bringing a new experience to users.
