The KUAIQU SPPS-C305 Adjustable DC Power Supply is a compact and easy-to-use bench power supply designed for student electronics labs, classroom experiments, electronics education, and hands-on circuit development.
With precise voltage and current adjustment, a clear 4-digit digital display, independent output control, and a compact high-density design, the SPPS-C305 provides students with a practical power source for learning, testing, and building electronic circuits.
The SPPS-C305 helps students move from circuit theory to practical experimentation by providing adjustable and measurable DC power for everyday electronics lab work.
Student electronics laboratories
Circuit theory and electronics experiments
Basic DC circuit testing
Breadboard circuit development
Arduino and microcontroller projects
Sensor and module experiments
LED and small electronic circuit testing
STEM and engineering education
DIY electronics projects
University and technical school laboratories
The SPPS-C305 features dual-knob encoders for smooth and precise voltage and current adjustment.
Students can easily adjust the output parameters while observing how changes in voltage and current affect their circuits.
Dual-knob encoder control
Smooth and precise adjustment
Adjustable voltage and current output
Easy-to-use front-panel controls
This makes the SPPS-C305 suitable for both introductory electronics experiments and more advanced student projects.
The built-in 4-digit LED display provides clear numerical readings during experiments.
Students can monitor:
Output Voltage
Output Current
Output Power
Real-time readings make it easier to understand the relationship between voltage, current, and power while performing circuit experiments.
The SPPS-C305 includes both a power switch and an independent output switch.
The output switch allows students to turn the DC output on or off without changing the configured voltage and current settings.
This is particularly useful when:
Connecting a new circuit
Repeating laboratory experiments
Replacing components
Troubleshooting wiring
Comparing different circuit configurations
Laboratory benches can quickly become crowded with oscilloscopes, multimeters, function generators, development boards, and other equipment.
The SPPS-C305 uses a compact, lightweight, high-power-density design to provide useful adjustable DC power while occupying less workspace.
It is suitable for:
School electronics labs
University engineering laboratories
Technical training classrooms
STEM education centers
Maker spaces
Home electronics workbenches
The SPPS-C305 also provides a 5V / 2A USB output for compatible USB-powered devices and electronics accessories.
This can be useful for student projects involving:
Development boards
USB-powered modules
Sensors
Small electronic accessories
Educational electronics kits
A temperature-controlled fan automatically manages cooling according to the operating condition.
The fan helps maintain stable operation during longer laboratory sessions while reducing unnecessary noise during lighter workloads.
Combined with its low-noise design, the SPPS-C305 is well suited to classrooms, teaching laboratories, and shared workspaces.
The SPPS-C305 can be used throughout the student electronics learning process:
Learn → Build → Measure → Test → Debug
Students can use the power supply to apply controlled DC power to a circuit, measure electrical behavior, test different operating conditions, and troubleshoot problems during hands-on experiments.
Basic Circuit Experiments
Power resistors, LEDs, switches, transistors, and other components while learning fundamental voltage and current concepts.
Arduino & Microcontroller Projects
Provide adjustable DC power for development boards, sensors, displays, and other modules used in student projects.
Breadboard Prototyping
Power temporary circuits during breadboard experiments and quickly adjust output parameters for different circuit configurations.
STEM & Engineering Education
Provide a practical laboratory power source for electronics classes, engineering courses, technical training, and hands-on STEM education.
The SPPS-C305 is designed for repeated use in educational and electronics development environments.
CE certified
ISO 9001 certified
Temperature-controlled cooling
Low-noise operation
Compact and lightweight design
Designed for long service life
The SPPS-C305 combines easy operation, precise adjustment, clear digital monitoring, independent output control, USB power, and compact construction in one practical bench power supply.
It is a suitable choice for students, teachers, electronics instructors, engineering departments, technical schools, STEM programs, and educational laboratories looking for a reliable adjustable DC power source for hands-on electronics learning.
