UNI-T calls it \"an economical benchtop tool for DIY electronics hobbyists, electronics manufacturing and testing\" — which is the most accurate one-line description we can offer. 150W of linear DC at 0–30V \/ 0–5A, in a footprint of 105 × 165 × 249 mm and a 4 kg net weight.\u003c\/p\u003e\n\u003cp\u003eA four-digit LED display reads voltage and current at 10 mV \/ 1 mA resolution per channel.

UTP3315TFL-II delivers 0–5A (150W total). UTP3313TFL-II delivers 0–3A (90W total). Voltage range, display, and physical dimensions are identical between the two. The 5A model has a slightly relaxed ripple spec (≤2 mVrms vs ≤1 mVrms) reflecting the higher-current rectifier stage.
