Siglent SPD3303C bench power supply 0-30V with triple programmable output and PC connection

The Siglent SPD3303C bench power supply is a high-precision unit designed to provide stable, programmable power in professional and laboratory environments. It features three independent outputs that offer great versatility for powering electronic projects, testing and development.

• High-precision independent outputs: Two channels with a 0-30V range and up to 3A, and a third channel with fixed 2.5V, 3.3V or 5V options, also with up to 3A.
• 195W total power: Enough to power multiple devices simultaneously with stability and safety.
• Clear digital display: LED displays with 4 digits for voltage and 3 digits for current, with minimum resolution of 10mV and 10mA for precise control.
• Flexible output modes: Allows operation in independent, series or parallel mode to suit different power needs.
• Compatibility with different mains supplies: Works with 100V, 120V, 220V and 230V, making it easy to use in various regions.
• Intelligent temperature-controlled fan: Reduces noise and improves the unit's thermal efficiency.
• Memory for saving settings: Stores and recalls up to 5 groups of specifications to speed up repetitive work.
• USB connection and SCPI support: Allows the power supply to be controlled from a PC, making it easy to integrate into automated systems and remote testing.
