The UNI-T UTP3305-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 160W of power each, over the range of 0-32V and 0-5A. 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 10A.

A disadvantage 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.

AI Overview BETA

The UNI-T UTP3305-II is a linear DC power supply that provides controlled voltage and current. The two adjustable channels can run in series or parallel, so users can configure their combined output for the required voltage or current. Lab users who need an output that cannot be adjusted have the third channel for that purpose in their setup.

Adjustable channels: 0–32 V, up to 5 A each
Total output power: 335 W
CV ripple: 1 mVrms; CC ripple: 3 mArms
Overload protection with current limiting
12-month warranty
