KUAIQU SPS-C305S 30V 5A 150W
Precision DC Bench Supply with 4-Digit
Display for PCB & Circuit Testing
The KUAIQU SPS-C305S is a 30V 5A 150W precision DC bench supply designed for PCB and circuit testing. With adjustable voltage and current, 10mV voltage setting resolution, 1mA current setting resolution, and a clear 4-digit display, it provides convenient parameter control and real-time monitoring during circuit development and board-level testing. Multiple protection functions help provide safer operation when testing electronic circuits and components.
Key Features
Precision Voltage and Current Adjustment
The SPS-C305S provides a 0–30V adjustable output and 0–5A adjustable current, giving engineers and technicians flexible control when evaluating different PCB and circuit operating conditions. The 10mV voltage setting resolution and 1mA current setting resolution allow fine parameter adjustment during circuit testing.
4-Digit Display for Real-Time Monitoring
The HD 4-digit display provides clear readings of voltage, current, and power. This allows users to monitor the electrical conditions of a PCB or circuit while adjusting test parameters, making it easier to observe changes during development and troubleshooting.
Precision DC Bench Supply for Circuit Work
The precision DC bench supply uses separate V-COARSE, V-FINE, A-COARSE, and A-FINE adjustment controls. This setup allows users to make both quick and fine adjustments when testing different circuit conditions, particularly during PCB development and component-level evaluation.
Independent Output Button
The dedicated Output Button allows the output to be controlled independently after the required voltage and current parameters have been set. This is convenient when connecting, testing, or adjusting a PCB without repeatedly changing the configured parameters.
OCP, OVP and Multiple Protection Functions
The SPS-C305S includes Over-Current Protection (OCP), Over-Voltage Protection (OVP), Over-Load Protection, Short Circuit Protection, Over-Temperature Protection, and Grounding Protection. These protection functions help reduce the risk of abnormal operating conditions during PCB and circuit testing.
USB and Type-C Charging Output
The front panel provides USB and Type-C charging outputs with defined PDO and PPS profiles. 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. This provides an additional power option for compatible devices used alongside circuit testing equipment.
Low-Ripple Output for Circuit Testing
With voltage ripple of ≤60mVp-p / ≤10mVrms and current ripple of ≤10mArms, the SPS-C305S provides regulated DC output suitable for a range of PCB and circuit test tasks where stable power conditions are important.
Applications
PCB Development and Board Testing
Use the SPS-C305S to supply adjustable DC power during PCB bring-up, functional checks, and board-level evaluation. The adjustable output and 4-digit monitoring make it convenient to observe how a board responds to different voltage and current conditions.
Circuit Testing and Troubleshooting
The adjustable voltage and current output supports testing circuits under different operating conditions. Fine adjustment controls allow users to make small parameter changes while monitoring voltage, current, and power readings on the 4-digit display.
Electronic Component Evaluation
The SPS-C305S can provide controlled DC power for evaluating electronic components and observing their behavior within a circuit. Its 1mA current setting resolution is useful when more precise current adjustments are required during testing.
Laboratory Electronics Projects
The compact DC bench supply is suitable for electronics development, circuit experiments, prototype testing, and other bench-based laboratory work requiring adjustable DC power.
