KUAIQU SPS-C305S 30V 5A 150W DC
Power Supply for Electronic Component
Testing
The KUAIQU SPS-C305S is a 30V 5A 150W adjustable DC power supply designed for electronic component testing and evaluation. With 10mV voltage setting resolution, 1mA current setting resolution, and a 4-digit display for voltage, current, and power, it provides controlled DC power and clear electrical readings during component evaluation. Multiple protection functions also help provide safer operating conditions when testing individual components under different electrical conditions.
Key Features
Fine Voltage and Current Control for Component Testing
The SPS-C305S provides 0–30V adjustable voltage and 0–5A adjustable current with 150W maximum output power. The 10mV voltage setting resolution and 1mA current setting resolution allow users to make fine changes to test conditions when evaluating electronic components and observing their electrical behavior.
Clear 4-Digit Electrical Readings
The 4-digit display shows voltage, current, and power readings in real time. During electronic component testing, users can monitor the actual electrical conditions while adjusting the supply, making it easier to observe parameter changes during evaluation.
Precision Adjustment Controls
Separate V-COARSE, V-FINE, A-COARSE, and A-FINE controls provide convenient adjustment of the output parameters. Coarse controls allow faster setting changes, while fine controls are useful when a component requires smaller voltage or current adjustments during testing.
Stable DC Output with Low Ripple
The SPS-C305S provides voltage ripple of ≤60mVp-p / ≤10mVrms and current ripple of ≤10mArms. This regulated DC output is suitable for component evaluation where controlled and stable power conditions are important for observing electrical performance.
OCP and Multiple Protection Functions
The power supply includes Over-Current Protection (OCP), Over-Voltage Protection (OVP), Over-Load Protection, Short Circuit Protection, Over-Temperature Protection, and Grounding Protection. These functions provide additional protection when connecting and testing electronic components under different operating conditions.
Independent Output Button
The dedicated Output Button allows users to control the DC output after setting the desired voltage and current. This makes it convenient to prepare test parameters before applying power to a component or test circuit.
USB and Type-C Charging Output
The SPS-C305S also provides USB and Type-C charging outputs. The USB/Type-C output supports PDO at 5V/3A, 9V/2A, and 12V/1.5A, while PPS supports 3.3V–5.9V/3A and 3.3V–11V/1.6A. These outputs provide an additional charging option for compatible devices used in an electronics testing workspace.
Applications
Electronic Component Evaluation
The SPS-C305S can provide adjustable DC power for evaluating electronic components under controlled voltage and current conditions. Users can adjust the output while monitoring voltage, current, and power readings.
Component Electrical Performance Testing
Different voltage and current settings can be applied when examining component behavior under varying operating conditions. The fine adjustment controls allow users to make smaller parameter changes during testing.
Semiconductor and Electronic Device Testing
The adjustable DC output can be used as a bench power source for testing compatible semiconductor devices and electronic components that require controlled DC input conditions.
Component-Level Troubleshooting
The SPS-C305S can support component-level troubleshooting by providing adjustable power while users observe electrical readings and changes in component behavior. OCP, OVP, Short Circuit Protection, and other protection functions provide additional safeguards during testing.
