The SPD3303X-E power supply belongs to the SPD3300X series of Siglent and has a resolution of 10mV/10mA and an accuracy of ±0.03% (V) and ±0.3% (A).

The SPD3300X series by Siglent is a line of high-end DC-power supplies with a 4.3-inch display. These power supplies offer three outputs that can be changed individually. Two outputs offer a maximum output voltage of 32 V, the third output can deliver a maximum of 5 volts and is, therefore, suited for most digital purposes like supplying a microcontroller.

The supplies offer the possibility to switch the two main outputs parallel or in series internally. This makes using the full output power of the supply easier and eliminates the need for extra wires.
