UNI-T UDP3305S power supply

The UNI-T UDP3305 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 high readback resolution of 1 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 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 can compete with other popular power supplies, such as the Rigol DP832 and the Siglent SPD3303X-E.
