The KUAIQU SPS305S is a 30V 5A 150W Precision DC Bench Supply designed for PCB & Circuit Testing. Its adjustable DC output provides flexible power conditions for circuit development, PCB debugging, prototype verification, and other compatible electronics testing tasks.
With a 0–30V output range, up to 5A current, and 150W maximum power, the SPS305S helps users configure suitable voltage and current conditions for different circuit requirements. The Precision Encoder supports detailed parameter adjustment, while the HD 4-Digit Display provides clear real-time readings during testing.
For users working with PCBs and electronic circuits, the combination of controlled DC output, independent output control, and built-in protection functions makes the SPS305S a practical bench power solution for daily electronics testing and development.
The SPS305S provides an adjustable 0–30V DC output, allowing users to supply different voltage levels for compatible PCBs, circuit boards, and electronic modules.
During circuit development and debugging, different projects may require different input conditions. The adjustable output helps users set an appropriate voltage within the rated range before testing the connected circuit.
With up to 5A output current and 150W maximum power, this Precision DC Bench Supply supports a variety of compatible PCB and circuit testing requirements.
Users can adjust voltage and current according to the requirements of the device or circuit under test while operating within the SPS305S rated output range.
The SPS305S uses precision adjustment controls to help users set output parameters more conveniently during circuit testing.
For PCB debugging and circuit development, users can make voltage and current adjustments when evaluating how a connected circuit responds to different power conditions. This is particularly useful when test parameters need to be changed gradually during troubleshooting.
The HD 4-Digit Display provides real-time readings of output voltage, current, and power.
During PCB & Circuit Testing, users can monitor electrical conditions while powering a circuit, helping them observe parameter changes as output settings or circuit operating conditions change.
The SPS305S allows users to configure the required voltage and current settings before enabling the output.
This helps create a more controlled testing workflow when connecting PCBs and electronic circuits, allowing output parameters to be prepared before power is applied to the device under test.
The built-in Over-Current Protection (OCP) and Over-Voltage Protection (OVP) provide additional protection during compatible electronics testing.
When abnormal current or voltage conditions occur, these protection functions help provide an additional layer of protection for the power supply and connected test setup.
The SPS305S includes multiple protection functions to support reliable bench operation, including protection against abnormal operating conditions.
These safety functions are particularly useful in PCB and circuit testing environments, where wiring errors, unexpected loads, or circuit faults may occur during development and troubleshooting.
In addition to its adjustable DC output, the SPS305S includes USB/Type-C output for charging compatible devices.
Supported output specifications include:
PDO: 5V/3A, 9V/2A, 12V/1.5A
PPS: 3.3V–5.9V/3A, 3.3V–11V/1.6A
This provides additional convenience for compatible devices used around an electronics workbench.
The SPS305S provides adjustable DC power for compatible PCB testing, circuit verification, and electronics troubleshooting within its rated output range.
Users can adjust voltage and current conditions while investigating circuit operation and identifying potential power-related issues during development.
The Precision DC Bench Supply can be used to provide controlled DC power when evaluating compatible PCB prototypes and electronic assemblies.
The 0–30V output range supports testing of compatible electronic modules that require adjustable DC input during development and verification.
With its adjustable output, HD 4-Digit Display, and precision control, the SPS305S is suitable for compatible electronics testing tasks in laboratories, workshops, educational environments, and development benches.
