The TPR3003T-3C and TPR3005T-3C series are high‑reliability regulated DC power supplies with constant‑voltage/constant‑current (CV/CC) conversion, over‑temperature, short‑circuit, and overload protection. They are suited for labs, electronic production lines, communication equipment maintenance, and other research or teaching environments.
The manual covers installation, wiring, operation modes (independent, series, parallel), current‑limit setting, safety precautions, and maintenance procedures. It also lists technical specifications such as input voltage, output ranges, accuracy, ripple, and environmental limits, helping users configure the unit safely and efficiently. This manual is written in Chinese.
