Equipped with a 2.8-inch full-color screen, this power supply clearly displays real-time USB voltage and current data. Built-in OCP (Over Current Protection) and OVP (Over Voltage Protection) deliver all-round protection to your devices, preventing damage from abnormal current and voltage.

Ideal for laboratory testing, electronic circuit debugging, PCB repair, DIY electronics projects and production line aging tests. It is a reliable working partner for engineers, technicians, researchers and electronic enthusiasts.

Three Powerful Core Functions

Real-Time Curve Display

The screen visualizes dynamic voltage and current change curves, letting you track operating status and data fluctuations intuitively during experiments and tests.
Dual-Mode Parameter Memory

For daily routine use, it offers 6 memory groups to store commonly used parameters for quick switching. When turning on the program control function, you can use up to 99 memory sets (M01~M99), which perfectly meets the demands of batch testing and complex experimental procedures.
Professional Slope Control

You can freely set the start value, end value, running time and cycle times of voltage and current. It achieves smooth automatic parameter adjustment, suitable for stepped power supply and cyclic testing scenarios.

Whether you are working in a professional lab, maintenance workshop or personal DIY workspace, this high-precision linear power supply will greatly boost your work efficiency. Place your order now and get a stable, multifunctional power source for all your electronic work!
