UNI-T UTP3303-II Linear DC Power Supply 3CH 335W 32V Adjustable Dual Channel and Fixed Single-Channel Output

The UNI-T UTP3303-II is a linear high-performance, yet affordable lab power supply that features two fully adjustable channels and one fixed channel. The adjustable channels can provide 96W of power each, over the range of 0-32V and 0-3A. The third channel provides a fixed output of 5V and 3A. Internally, the adjustable channels can be connected in series or parallel, delivering respectively a maximum voltage of 64V or a maximum current of 6A. The UNI-T UTP3305-II power supply is an alternative power supply from the same series.

A disadvantage of UNI-T UTP3303-II is that the power supply only has a ‘coarse’ adjustment knob, making it more difficult to set the power supply precisely. Also, the 3rd channel is fixed, which means that it is not possible to set a different voltage, for example 3.3V. The power supply also has one button to switch all channels on or off simultaneously, which makes it impossible to switch individual channels on or off.
