KUAIQU SPPS-C305 0-30V 0-5A 150W DC
Bench Power Supply with Encoder
Adjustment for Breadboard Testing
The KUAIQU SPPS-C305 0-30V 0-5A 150W DC Bench Power Supply is designed for breadboard circuit testing, electronic prototyping, and hands-on circuit development. With encoder adjustment, adjustable DC output, and real-time Voltage, Current, and Power Display, it provides direct control and visibility when powering and testing prototype circuits. The CV/CC automatic switching and independent output switch further support repeated circuit setup, adjustment, and verification on an electronics workbench.
Key Features
Precision Encoder Adjustment for Circuit Prototyping
The SPPS-C305 features a dual-knob encoder adjustment system for precise voltage and current setting. The encoder design allows users to make controlled adjustments while developing and testing breadboard circuits, making it easier to fine-tune the DC supply according to the requirements of different prototype circuits.
0-30V 0-5A Adjustable DC Output
With a 0-30V voltage range, 0-5A current range, and 150W maximum output power, the SPPS-C305 provides adjustable DC power for breadboard circuits and compatible electronic components within its rated operating range. The adjustable output allows users to establish different supply conditions during circuit development and testing.
Voltage Current and Power Display
The 4-digit display provides clear Voltage, Current, and Power Display information during operation. Users can monitor the electrical conditions of a breadboard circuit while testing, helping them observe current consumption and power changes as circuit components or connections are adjusted.
CV/CC Automatic Switching
The SPPS-C305 supports CV/CC automatic switching during operation. This allows the power supply to operate in constant voltage or constant current conditions according to the connected load, providing useful operating feedback when testing prototype circuits and electronic components.
Independent Output Switch for Testing
The independent output switch allows users to turn the DC output on or off while keeping the configured settings available. This is useful when connecting a breadboard circuit, changing circuit connections, or repeating a test without repeatedly setting the desired output values.
Compact Bench Design with USB 5V/2A Output
The compact DC Bench Power Supply is suitable for electronics workbenches, classrooms, laboratories, and development areas where bench space is limited. The built-in USB 5V/2A output provides an additional power source for compatible USB-powered devices used during electronics development and testing.
Applications
Breadboard Circuit Testing
The SPPS-C305 provides adjustable DC power for breadboard-based circuit testing and prototype verification. Users can set the required voltage and current, connect the circuit to the output terminals, and monitor Voltage, Current, and Power Display readings during operation.
Electronic Circuit Prototyping
The adjustable DC output is suitable for powering prototype circuits during the development process. Encoder adjustment allows users to make controlled changes to voltage and current while evaluating circuit behavior and testing different operating conditions.
Component and Module Testing
Within its 0-30V, 0-5A, and 150W rated output range, the SPPS-C305 can supply compatible electronic components, sensors, small modules, and other low-voltage test circuits. Real-time voltage, current, and power readings provide useful operating information during bench testing.
Electronics Education and Laboratory Experiments
The DC Bench Power Supply can be used for classroom experiments, student breadboard projects, laboratory circuit demonstrations, and basic electronics development. Its adjustable output, encoder adjustment, CV/CC operation, and clear electrical display make it suitable for hands-on circuit testing.
