Description
The YIHUA 3010D-V PRO Digital DC Power Supply is designed for professional electronics technicians, engineers, laboratories, repair workshops, students, and makers who need a powerful and highly configurable bench power source.
Its main output is continuously adjustable from 0 to 30V DC with current adjustment from 0 to 10A, providing a maximum DC output of 300W. The supply supports both Constant Voltage (CV) and Constant Current (CC) operation, allowing precise control when powering sensitive circuits or limiting current during troubleshooting.
A major advantage of the PRO version is its three memory channels – CH1, CH2 and CH3. Frequently used voltage and current settings can be stored for faster recall. Dedicated quick-selection settings for 5V, 8.4V and 12V further simplify common repair and testing tasks.
The front panel also provides multiple USB outputs. A USB Type-C port supports fast charging up to 65W, while a USB-A Quick Charge output supports up to 40W. Additional USB connections expand the unit’s usefulness when working with mobile devices, development boards, and other electronics.
For protection, the 3010D-V PRO includes OCP over-current protection with CONT and ONCE operating modes, as well as protection against short circuits and excessive operating conditions. An intelligent cooling system and toroidal transformer help support stable bench operation.
