Description
The YIHUA 3010D-V DC Power Supply 30V 10A USB Adjustable Laboratory Switching Power Supply Voltage Regulator Soldering Repair Tool is a high-performance, precision-engineered laboratory power solution designed to meet the demanding needs of electronics professionals, repair technicians, R&D engineers, and advanced hobbyists. Built for stability, efficiency, and safety, this versatile DC power supply delivers adjustable output from 0–30V and 0–10A, making it suitable for a wide range of testing, development, maintenance, and production applications.
Whether you are troubleshooting PCBs, powering embedded systems, testing electronic modules, repairing smartphones, or conducting laboratory experiments, the YIHUA 3010D-V DC Power Supply ensures accurate voltage delivery, low ripple output, and dependable performance for daily professional use.
Features
Precision Adjustable Output for Professional Applications
At the core of the yihua 3010d-v dc power supply is its fully adjustable 0–30V voltage and 0–10A current output, allowing users to fine-tune power settings according to specific project requirements. This wide output range makes it ideal for:
-
Circuit board testing
-
Microcontroller and Arduino projects
-
Mobile phone and laptop motherboard repair
-
Battery charging simulations
-
LED driver testing
-
Automotive electronics diagnostics
-
R&D prototype development
The high load regulation ensures consistent voltage levels even when connected devices draw varying currents. With low ripple and noise characteristics, the unit delivers clean and stable DC output, protecting sensitive electronic components from fluctuations and interference.
Advanced Protection for Safe Operation
Safety is critical in laboratory and repair environments. The YIHUA 3010D-V DC Power Supply integrates multiple intelligent protection systems to safeguard both the device under test and the power supply itself.
Built-in Protection Features:
-
Short-Circuit Protection – Automatically limits output during accidental short circuits.
-
Overcurrent Protection (OCP) – Prevents excessive current from damaging circuits.
-
Overheat Protection – Internal thermal monitoring protects against overheating.
-
Auto-Stop & Auto-Resume Modes – Ensures safe and controlled operation during overload conditions.
These safety mechanisms make this dc power supply suitable for professional repair centers, training labs, and production lines where reliability is essential.
High-Efficiency Toroidal Transformer Design
One of the standout features of the Yihua DC supply is its high-efficiency toroidal transformer. Compared to conventional transformers, the toroidal design offers:
-
Lower heat generation
-
Reduced energy loss
-
Improved efficiency
-
Compact internal layout
-
Enhanced electromagnetic shielding
This ensures quieter operation, longer service life, and stable performance even during extended working hours. For technicians working in busy repair environments, reduced heat output means greater reliability and comfort.
Constant Voltage (CV) and Constant Current (CC) Modes
The YIHUA 3010D-V DC Power Supply supports both Constant Voltage (CV) and Constant Current (CC) modes, making it adaptable for different types of electronic testing.
Constant Voltage Mode (CV)
Maintains a stable voltage output while allowing current to vary depending on the load. Ideal for powering circuits that require fixed voltage.
Constant Current Mode (CC)
Maintains a fixed current level, automatically adjusting voltage as needed. Perfect for LED testing, battery charging simulations, and component stress testing.
The intelligent switching between CV and CC ensures optimal performance and protection across multiple applications.

Great pillow
Color: Black and White
This has helped with my neck issues. It does stay cool and keeps me from sweating like my old one, but I do wish it stayed cold.

Perfect pillow
Color: Black and White
I love this pillow! At first I was afraid it was too thick but it's perfect. I have a lot of neck issues and this pillow has stopped all the pain that I used to feel when waking up! The price is good and it works great.
