14-Digit Display & Power Calculation: The SPS series features a big bright 4-digit LED display that shows measured values of VAW that the unit outputs in real-time. The display resolution is up to 0.01V, 0.001A, and 0.1W. 2Auto C.V. and C.C. Mode: The SPS series can be used as a constant-voltage*(C.V.) power supply and constant-current*(C.C.) power supply even when the load is changed. It switches automatically between CV mode and CC mode according to the changes in the load. Note: The V and A settings you set are the crossover point at which the mode switches. 3Compact Body & Lightweight: The SPS series measured only 7.1(D)x3.35(W)x6.1(H)inches and weight of approx. 2.5lbs. It saves space on your workbench and can be moved around without any frustration. 4Reliability and Safety: The SPS series is built with high-quality materials and reliable circuit designs that include multiple protection functions, such as short-circuit protection, over-load protection, grounding terminal, temperat
