The KUAIQU SPS305S is a 30V 5A 150W Precision DC Test Supply designed for Electronic Component Testing, providing stable and adjustable DC power for compatible electronic components, modules, and circuit evaluation applications.
With a 0–30V adjustable voltage range, up to 5A output current, and 150W maximum power, the SPS305S allows engineers and technicians to establish different power conditions when evaluating component performance within the rated output range.
Equipped with Over-Current Protection (OCP), precision voltage and current adjustment, and a 4-Digit Display, the SPS305S helps users monitor electrical parameters and apply controlled DC power during electronic component testing and verification.
The SPS305S provides a 0–30V adjustable DC output, allowing users to set suitable voltage conditions for compatible electronic components, circuit modules, and testing setups.
During component evaluation, different devices may require different operating voltages. The adjustable output enables engineers to test components under various DC power conditions within the rated specifications.
With up to 5A output current and 150W maximum power, the SPS305S provides flexible power support for compatible electronic components and electronic circuits.
Users can adjust voltage and current parameters according to the requirements of tested components, helping evaluate component operation under different power conditions.
The SPS305S features Over-Current Protection (OCP) to help protect connected devices when excessive current conditions occur during testing.
This function provides additional safety when evaluating electronic components, circuit modules, and prototypes with different current requirements.
The SPS305S supports precise parameter adjustment with:
Voltage Setting Resolution: 10mV
Current Setting Resolution: 1mA
The fine adjustment capability allows users to make controlled changes to output conditions when testing electronic components that require accurate voltage and current settings.
The integrated 4-Digit Display provides real-time readings of:
Output Voltage
Output Current
Output Power
During Electronic Component Testing, users can observe electrical parameter changes and monitor the power conditions supplied to connected components.
The SPS305S includes an Output Control function, allowing users to configure voltage and current settings before enabling the DC output.
This helps users prepare testing conditions in advance and apply power to connected components in a more controlled manner.
The SPS305S includes USB / Type-C output capability for compatible devices used in electronics workstations.
Supported output:
PDO: 5V/3A, 9V/2A, 12V/1.5A
PPS: 3.3V–5.9V/3A, 3.3V–11V/1.6A
This additional output provides convenient power support for compatible equipment used alongside electronic testing setups.
The SPS305S integrates multiple protection functions, including:
Over-Voltage Protection (OVP)
Over-Current Protection (OCP)
Over-Load Protection
Short Circuit Protection
Over-Temperature Protection
Grounding Protection
These protection functions help improve operational safety when testing electronic components and connected circuits under different operating conditions.
With a compact size of approximately 22 × 8.5 × 15.5 cm and a net weight of about 1.2 kg, the SPS305S is suitable for electronics laboratories, repair workstations, and component testing environments.
The SPS305S provides controlled DC power for evaluating compatible electronic components, modules, and circuit assemblies.
The adjustable voltage and current output allow users to establish different test conditions within the rated operating range.
The Precision DC Test Supply helps engineers monitor voltage, current, and power changes when evaluating electronic component behavior under different DC input conditions.
The SPS305S can provide adjustable DC power for compatible circuit modules and electronic assemblies during development and verification.
