Description
The YIHUA 305D / 305D-II is a single-output regulated laboratory DC power supply designed for electronics technicians, engineers, students, laboratories, production environments, and repair workshops.
Its output voltage can be continuously adjusted from 0 to 30V DC, while the current can be adjusted from 0 to 5A, providing a maximum output capacity of approximately 150W. This makes it suitable for powering electronic circuits, development boards, modules, LEDs, motors, communication equipment, and other low-voltage DC devices.
The power supply automatically operates between Constant Voltage (CV) and Constant Current (CC) modes. In CV mode, the selected output voltage is maintained while current changes according to the connected load. In CC mode, the power supply limits the current to the selected value, which is particularly useful when testing prototypes or sensitive electronic circuits.
Dual digital displays allow voltage and current to be monitored independently. The YIHUA 305D series also incorporates protection against over-current, short circuit, and excessive temperature, helping provide safer operation during electronics testing and troubleshooting.
