Siglent SPD3303X-E - 3-channel programmable laboratory power supply 32V 3.2A

Description

Siglent SPD3303X-E is a linear, programmable DC laboratory power supply from the SPD3000X series, designed for use in laboratories, R&D departments, and production lines. The device offers three independent and galvanically isolated outputs, including two fully adjustable channels and one fixed-voltage output of 2.5 V / 3.3 V / 5 V. The total output power of 220 W allows it to supply a wide range of electronic circuits.

The power supply is equipped with a 4.3-inch color TFT-LCD display that shows voltage, current, and real-time waveforms. The clear graphical interface significantly improves ease of use and parameter control. The device supports independent, series, and parallel operating modes, increasing application flexibility. High resolution and programming accuracy enable precise power setting. Built-in short-circuit and overload protection ensure safe operation with sensitive circuits.

An intelligent, temperature-controlled fan effectively reduces noise. The power supply supports remote control and programming via USB and LAN. The included Easypower software enables integration with test systems and supports SCPI and LabVIEW protocols. The SPD3303X-E is a reliable tool for engineers, technicians, and technical education. It is well suited for both design and testing of electronic devices. Solid construction and high parameter stability ensure long-term operation. It is a power supply that combines precision, functionality, and modern usability.
