The KUAIQU MPS-305QC Adjustable DC Power Supply is a compact test and power solution designed for sensor research and development, sensor calibration, low-power device testing, and electronic measurement.
During sensor development and calibration, a stable and adjustable power source is essential for evaluating sensor behavior under different voltage and current conditions. The MPS-305QC provides adjustable DC output, real-time voltage/current monitoring, USB-A & USB-C power analysis, protection functions, and convenient output control for laboratory and engineering applications.
It is suitable for testing and validating:
Sensor operating current
Sensor power consumption
Supply-voltage response
Low-power sensor modules
IoT sensor devices
Embedded sensor boards
Measurement and control circuits
USB-powered sensing devices
The clear 4-digit LED display provides real-time voltage and current readings.
During sensor development and calibration, engineers can monitor changes in power consumption while adjusting supply voltage or changing operating conditions.
This helps evaluate:
Sensor operating current
Standby and working current
Power consumption changes
Abnormal current behavior
Voltage-dependent performance
The adjustable DC output allows engineers to provide different supply conditions during sensor development and calibration.
By changing the output voltage, users can evaluate how sensors, modules, and embedded circuits respond under different power conditions.
This is useful for:
Sensor characterization
Calibration testing
Prototype verification
Power-supply tolerance testing
Operating-voltage evaluation
The built-in USB monitoring function independently displays voltage and current values for USB-A and USB-C outputs.
It can be used to evaluate the power consumption of USB-powered sensor modules, development boards, IoT devices, and other embedded electronics.
USB power monitoring helps engineers identify:
Abnormal power consumption
Charging and power delivery behavior
Current fluctuations
USB-powered device performance
The MPS-305QC incorporates Over Voltage Protection (OVP) and Over Current Protection (OCP) to provide additional protection during development and testing.
If abnormal voltage, excessive current, or a short circuit occurs, the protection system helps reduce the risk of damage to sensitive sensor modules, ICs, and electronic components.
The panel lock function helps prevent accidental adjustment of voltage and current settings during long-duration testing and calibration.
This is particularly useful when the power supply is used for repeated measurements, automated test setups, or extended sensor evaluation.
The dedicated OUTPUT button allows engineers to turn the DC output ON or OFF without shutting down the entire power supply.
This makes it easier to:
Connect and disconnect sensor modules
Change test configurations
Repeat calibration tests
Switch between test conditions
Protect devices during connection
The integrated wireless charging area can also be used for evaluating wireless-powered devices and charging-related electronic products.
Place a compatible device on the top surface for quick functional verification without additional charging equipment.
The MPS-305QC includes USB-A and USB-C smart charging interfaces for testing modern USB power applications.
USB-A: QC fast charging testing
USB-C: PD fast charging protocol testing
These interfaces are useful when developing or evaluating USB-powered sensor devices, portable electronics, IoT products, and embedded systems.
The wide voltage input design allows the MPS-305QC to operate across different regions and power environments.
It is suitable for:
Sensor R&D laboratories
Electronics development workshops
Calibration environments
Engineering test benches
Educational laboratories
Production testing
Provide stable and adjustable power during sensor prototype development, functional verification, and electrical characterization.
Monitor voltage and current while calibrating sensors under different operating conditions.
Useful for evaluating sensor response, operating current, and power consumption during calibration procedures.
Monitor small changes in current consumption when testing low-power sensors, embedded modules, and battery-powered electronics.
Suitable for powering and testing sensor nodes, development boards, wireless modules, and other embedded electronic systems.
Evaluate sensor modules under different supply-voltage and load conditions before integration into a larger system.
Provide a convenient DC power source for repeated functional checks, power-consumption verification, and quality-control testing of sensor-related electronic products.
Suitable for engineers working with measurement circuits, control boards, communication modules, and other low-voltage electronic systems.
Stable Power Supply
Provides adjustable DC power for controlled sensor testing and calibration.
Real-Time Monitoring
Observe voltage and current changes while testing sensor operating conditions.
Low-Power Evaluation
Useful for analyzing power consumption and current behavior of electronic sensor modules.
Multiple Test Interfaces
DC output, USB-A, USB-C, and wireless charging functions support different electronic testing scenarios.
Protection for Prototypes
OVP and OCP protection help reduce the risk of accidental damage during R&D and calibration.
Compact Engineering Workstation
Combines DC power supply and USB power testing functions into one compact bench-top instrument.
