Details

The UNI-T UDP3305-E is a linear DC power supply which features a total of four channels, and a power output of 348 W. The first two channels are both 32 V / 5 A and have the option of being internally connected in either series or parallel operation. The third channel of the UDP3305 can be set to 6 V / 3 A and the fourth channel is a fixed 5 V USB output, with a maximum current of 2 A.

This power supply sets itself apart from other competitors because of its high price to quality ratio, as it comes with a readback resolution of 10 mV / 1mA, in combination with features such as real-time waveform display and extensive connectivity capabilities with USB, RS232, LAN and digital I/O. Furthermore, the UTD3305-E supports SCPI, which makes it possible to program the power supply.
In addition, it is possible to power each channel on or off individually, and the large 4.3" display gives a detailed overview of up to 3 channels at the same time. It is because of these features that the UDP3305-E can compete with other popular power supplies, such as the Rigol DP832 and the Siglent SPD3303X-E.

The default 3-year warranty can be extended to 5 years by registering your instrument.

Review by Sercan 
Posted on 28/04/2026
I bought the Uni t UDP3305S-E power supply for audio circuit design and measurements. It's easy to use and has a quiet regulator. Specifically, at 12V 100mA, the output noise is only 16uV (20-20kHz BW). I recommend it.
