Get lab-grade voltage and current control on your own bench with the YIHUA 3010D-III.
The YIHUA 3010D-III Bench Power Supply delivers a fully adjustable 0-30V, 0-10A output from a compact 300W switching-mode unit, giving repair technicians and hobbyists precise, repeatable power for testing boards, simulating batteries, and driving bench projects.
Top Features
- Digital Encoder Knobs: Turn slowly for 10mV/1mA fine adjustment, or spin faster to jump in bigger steps.
- Triple LED Readout: Voltage, current, and power all shown at once, no toggling between screens.
- Auto CC/CV Switching: Moves between Constant Voltage and Constant Current automatically, with LED mode indicators.
- Built-In Protection: Short-circuit alarm, overcurrent protection, and a temperature-controlled cooling fan.
- Series/Parallel Ready: Pair two units when a project needs more voltage or current headroom.
