Design Features

The SPD3303C exhibits high resolution, 10 mV / 10 mA, providing the user with excellent settability and read back accuracy. In addition, it maintains its ability to change output voltage or current in small increments while fully meeting the power requirements of the load.

Intelligent fan for temperature control, effectively reduces noise.

Series/parallel/independent output modes View more

Series/parallel/independent output modes

Series-parallel function combines two power supplies into one and makes it very convenient for many applications. The 3303C has three independent outputs which can be controlled separately and also be turned on or off separately or at the same time.
