Description
The YIHUA 3005D-II is a versatile dual-channel adjustable DC bench power supply designed for electronics technicians, engineers, laboratories, educational institutions, production environments, and electronics repair workshops.
It provides two independent adjustable channels, with each channel capable of supplying 0–30V DC and 0–5A. For applications requiring a higher voltage or current, the channels can be combined using the built-in tracking modes. In series mode, the unit can provide up to 60V at 5A, while parallel mode provides up to 30V at 10A.
In addition to the two adjustable outputs, the station features a third output with selectable 2.5V, 3.3V, or 5V levels and a rated current of up to 3A. This is especially convenient for powering digital circuits, microcontrollers, logic systems, sensors, and other low-voltage electronics.
The power supply supports Constant Voltage (CV) and Constant Current (CC) operation and features digital displays for monitoring output values. Its internal copper transformer and temperature-controlled cooling fan are designed to support reliable operation during extended bench use.
