Product Introduction
The SIGLENT SPD3303C Programmable DC Power Supply is a LED display screen and programmable linear DC power supply that is both lightweight and feature-packed. It has three independent outputs: two sets of adjustable voltage / current and a fixed set of selectable voltages; 2.5, 3.3, and 5 V. In addition, the SPD3303C DC power supply has outputs that are short-circuit and overload protected. Total power is 220 W.

Key Features

• Total 220 W power
• 4 digit voltage and 3 digit current display, min resolution: 10 mV, 10 mA
• 100/120/220/230 V compatible design
• Three output modes: independent, series and parallel
• 3 independent high precision outputs: two 32 V /3.2 A, one 2.5 V / 3.3 V / & 5 V / 3.2 A

Product Advantage

Robust Output Performance
The SPD3303C is robust and stable, and can accurately simulate even small voltage or current changes, fully meeting the power requirements of the load.

· Ultra-high resolution: 1 mV, 1 mA
· Excellent setting and readback accuracy to ensure accurate and pure output
· 3 independently controlled and isolated outputs


Series/parallel/independent Mode
The series-parallel function combines two power supplies into one power supply, which expands the output power range of a single power supply, which brings convenience in some applications. The three independent power supplies can individually control the output switch, and they can be turned on or off at the same time.
