This is the user manual of DH1719A regulated voltage/current power supply produced by Dahua Company
The DH1719A is a regulated adjustable voltage/current power supply with a 3½‑digit display. It provides both constant‑voltage (CV) and constant‑current (CC) modes, selectable via an electronic output switch that eliminates spark and noise. The front panel shows voltage and current values, while LEDs indicate the active mode (green for CV, red for CC).
The manual describes operating features, principle of operation, structure, applications, maintenance, storage, and warranty information. It also details remote‑control options, adjustment procedures, and safety precautions for proper use of the instrument. This manual is written in Chinese.
