SPD3303X, 3 Channel Programmable DC Power Supply, 32V/3.2A Adjustable + Fixed, 220 W Total

The Siglent SPD3303X is a high-precision, three-channel programmable linear DC power supply ideal for laboratory and industrial environments. It offers two adjustable channels (0–32 V, 0–3.2 A each) and one fixed-selectable channel (2.5 V, 3.3 V, or 5 V at 3.2 A), delivering a total output power of 220 W. Featuring a 4.3″ color TFT-LCD with real-time waveform display and front-panel timing output, the device supports independent, series (up to 60 V), and parallel (up to 6.4 A) operation modes. With ultra-fine resolution (1 mV/1 mA), fast transient response (<50 µs), low ripple (<300 µV rms), and robust protections, this unit is tailored for research, production, and automated test systems. Remote control via USB and LAN is enabled through EasyPower software with SCPI and LabView support.
