KUAIQU SPS-C305S 30V 5A 150W
Adjustable DC Power Supply with HD
Display for University Lab Experiments
The KUAIQU SPS-C305S is a 30V 5A 150W Adjustable DC Power Supply designed for university laboratory experiments, electronics teaching, circuit projects, and student research. With precision voltage and current adjustment, an HD 4-Digit Display, low-ripple DC output, and multiple protection functions, it provides practical and controlled power for a wide range of laboratory testing tasks.
Key Features
Adjustable Voltage and Current for Laboratory Experiments
With a 0–30V adjustable voltage range and 0–5A adjustable current output, the SPS-C305S allows students and researchers to set appropriate power conditions for different experimental circuits and electronic devices. The adjustable DC output makes it suitable for repeated laboratory experiments requiring different voltage and current levels.
HD 4-Digit Display for Clear Experimental Readings
The HD 4-Digit Display provides clear real-time readings of voltage, current, and power. This allows students to observe electrical parameters directly during experiments and makes it easier to record and compare test results.
Precision Encoder for Fine Parameter Adjustment
The Precision Encoder with V-COARSE, V-FINE, A-COARSE, and A-FINE controls provides flexible adjustment of output voltage and current. Coarse adjustment helps quickly reach the desired range, while fine adjustment is useful when laboratory experiments require more precise parameter settings.
Stable DC Output with Low Ripple
The SPS-C305S provides regulated DC output with low ripple, supporting experiments where stable power conditions are important. Its voltage ripple is specified at ≤60mVp-p / ≤10mVrms, helping provide a consistent power source for laboratory circuits and electronic components.
OCP and Multiple Protection Functions
For safer laboratory operation, 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 protection functions help reduce risks caused by abnormal operating conditions during student experiments and electronics testing.
Independent Output Button for Convenient Operation
The Independent Output Button allows users to control DC output separately from parameter adjustment. Students can prepare the required voltage and current settings before activating the output, making operation more convenient during laboratory procedures.
USB and Type-C Charging Output
The built-in USB and USB Type-C charging outputs provide convenient charging support for compatible devices used alongside laboratory work. The USB/Type-C output supports PDO profiles of 5V/3A, 9V/2A, and 12V/1.5A, as well as PPS output of 3.3V–5.9V/3A and 3.3V–11V/1.6A.
Low-Noise Cooling for Laboratory Environments
The integrated cooling fan helps manage operating temperature while the low-noise design is suitable for laboratory environments where students and researchers need to work around the equipment for extended periods.
