Description
The YIHUA YH-305D 30V 5A DC Power Supply is a compact and reliable laboratory power source designed for electronics servicing, testing, development, and educational applications. It provides continuously adjustable output voltage from 0 to 30V and output current from 0 to 5A, allowing precise control for a wide range of electronic circuits and devices.
The unit features a clear dual LED digital display for monitoring voltage and current during operation. It can operate in both Constant Voltage (CV) and Constant Current (CC) modes, with smooth adjustment for precise output control.
Built with an all-metal housing and an integrated cooling fan with thermal control, the YH-305D is designed for reliable operation. Its short-circuit, overload, and current protection features help protect both the power supply and connected equipment from accidental damage.
The YH-305D is suitable for electronics repair shops, laboratories, research institutions, educational projects, computer servicing, automotive electronics, and general bench testing.
