The KUAIQU MPS-305QC Adjustable DC Power Supply is a compact test power solution designed for micro motor control boards, motor driver boards, embedded control circuits, and electronics development.
During micro motor development and troubleshooting, engineers need a stable and adjustable DC power source to evaluate startup current, operating current, standby consumption, voltage stability, short-circuit conditions, and abnormal power consumption.
The MPS-305QC combines an adjustable DC power supply with real-time voltage/current monitoring, USB-A & USB-C testing, OVP/OCP protection, output control, and wireless charging test capability, making it suitable for both motor control board development and electronics troubleshooting.
It is ideal for testing:
Provides a stable adjustable DC power source for powering micro motor control boards and driver circuits during development and troubleshooting.
Engineers can adjust the supply voltage according to the test requirements and observe how the control board responds under different operating conditions.
This is useful for evaluating:
The 4-digit LED display provides real-time voltage and current readings.
During motor control board testing, engineers can monitor changes in power consumption when the motor:
Current fluctuations can help identify driver circuit problems, abnormal power consumption, component faults, and potential short circuits.
The MPS-305QC is particularly suitable for testing compact electronic control systems used in:
It provides engineers with a convenient bench power source during PCB debugging, firmware development, driver IC testing, and prototype validation.
Built-in Over Voltage Protection (OVP) and Over Current Protection (OCP) help protect the power supply and connected test boards during abnormal operating conditions.
When excessive current, abnormal voltage, or a short circuit occurs, the protection system helps reduce the risk of damage to sensitive components such as:
This is especially useful during early-stage prototype debugging when circuit faults may occur frequently.
The dedicated OUTPUT button allows engineers to quickly turn DC output ON or OFF without shutting down the entire power supply.
This makes repeated testing more convenient when:
The panel lock function helps prevent accidental adjustment of voltage and operating controls during testing.
This is useful for long-duration motor control board testing and repeated laboratory measurements, where stable test conditions are important.
The built-in USB-A and USB-C monitoring functions independently display voltage and current values.
USB-A supports QC fast charging testing, while USB-C supports PD fast charging protocol testing.
Although designed primarily as an electronics test feature, the USB monitoring functions also make the MPS-305QC useful for engineers working with USB-powered control boards, embedded devices, portable electronics, and mixed power systems.
The integrated wireless charging test area allows compatible devices to be placed directly on the top surface for quick charging verification.
This makes the MPS-305QC more versatile for electronics laboratories that work with motor control systems, portable electronics, charging circuits, and embedded devices.
The wide input voltage design supports operation across different countries and regions.
It is suitable for:
Provides stable DC power for testing micro motor control boards and electronic drive circuits, including startup, operating, and standby conditions.
Suitable for evaluating motor driver circuits, MOSFET switching stages, control ICs, and related power components.
Useful for powering and debugging control boards used with brushless DC motors and brushed DC motors.
Provides a stable power source for MCU-controlled motor systems, allowing engineers to monitor board current consumption while testing firmware and control logic.
Monitor current changes to help identify short circuits, abnormal consumption, component faults, and power-related PCB problems.
Suitable for prototype testing and development of compact control boards used in robotics, smart devices, appliances, automation equipment, fans, pumps, and actuators.
Also suitable for smartphone motherboard repair, charging circuit testing, USB power testing, and general electronic troubleshooting.
A motor control board can have significantly different power characteristics during startup, acceleration, steady-state operation, and standby.
The MPS-305QC allows engineers to observe these current changes directly from the front-panel display.
This makes it easier to evaluate:
Startup Current → Operating Current → Standby Current → Abnormal Current → Fault Diagnosis
For R&D engineers and technicians, this provides a simple way to understand how a motor control circuit behaves under different operating conditions before moving to more advanced test equipment.
