The PPS300 series are single‑programmable power supplies offering high stability, low ripple and both digital and analog control features. They provide output voltages up to 30 V and currents up to 3 A (PPS3003S) or 5 A (PPS3005S) with a maximum power of 150 W.
The manual explains safety precautions, how to adjust voltage and current using the VSET and ISET keys, storage of settings, and protection mechanisms such as over‑current, over‑voltage and over‑temperature. Interface options, environmental limits and front‑panel layout are also described.
