Accurately supply your needs of stability and versatility!

The SPD3303C is a LED display screen 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 ‘3303C has outputs that are short-circuit and overload protected. Total power is 220 W. It has three available operation modes; independent, series and parallel modes. The SPD3300C has a high performance-to-price ratio and can be used in various types of production, education and research environments.

It is designed with three groups of independent output terminals, the output voltage of two groups is adjustable and another group is fixed to select: 2.5V, 3.3V, and 5V. The instrument also provides output short circuit and overload protection.

Main Features

  • 3 independent high precision outputs: two 32 V /3.2 A, one 2.5 V / 3.3 V / & 5 V / 3.2 A, total 220 W power

  • 4 digit voltage and 3 digit current display, min resolution: 10 mV, 10 mA

  • Three output modes: independent, series and parallel

  • 100/120/220/230 V compatible design, to meet the needs of various power grids
