MPS-305QC Adjustable DC Power Supply for Embedded MCU Board Debugging & PCB Leakage Inspection

The KUAIQU MPS-305QC Adjustable DC Power Supply is designed for embedded hardware development, MCU board debugging, PCB troubleshooting, and low-power electronic testing.

During embedded system development, engineers need a stable and adjustable power source to analyze abnormal current consumption, verify power circuits, and optimize energy efficiency.

With real-time voltage/current monitoring, adjustable output control, OVP/OCP protection, and USB-A & USB-C power analysis capability, the MPS-305QC helps engineers quickly identify:

  • MCU board power issues
  • Excessive standby current
  • Sleep mode power consumption problems
  • PCB leakage current
  • Short circuits and component failures
  • Abnormal power rail behavior

It is an ideal bench power supply for embedded development, IoT hardware testing, PCB repair, and electronics laboratories.

Key Features

1. Embedded MCU Board Low Power Debugging

Modern embedded devices require extremely low standby power consumption to extend battery life.

The MPS-305QC provides stable DC output and real-time current monitoring for debugging:

  • ARM Cortex MCU boards
  • ESP32 / STM32 development boards
  • IoT controller boards
  • Sensor modules
  • Battery-powered embedded devices

Engineers can observe current changes during:

Power ON → Active Operation → Sleep Mode → Wake-up Process

Helping optimize:

✔ Firmware power management
✔ MCU sleep modes
✔ Peripheral power control
✔ Battery operating time

2. PCB Leakage Current Inspection & Fault Diagnosis

Unexpected current consumption is often caused by:

  • PCB leakage paths
  • Incorrect component selection
  • Damaged ICs
  • Poor soldering
  • Power circuit design issues

The MPS-305QC allows engineers to monitor current behavior and quickly locate abnormal conditions during PCB testing.

Typical applications:

  • New PCB prototype validation
  • Hardware debugging
  • Component replacement testing
  • Circuit fault analysis

3. Real-Time Voltage & Current Monitoring

Clear 4-Digit LED Display

The high-visibility display provides real-time feedback of:

  • Output voltage
  • Output current

Engineers can easily detect:

  • Current spikes
  • Unexpected standby consumption
  • Power fluctuations
  • Abnormal load conditions

This helps reduce troubleshooting time during hardware development.

4. Stable Adjustable DC Output for Embedded Systems

The MPS-305QC provides a flexible adjustable power source for different electronic designs.

Suitable for:

  • MCU development boards
  • Prototype PCB testing
  • Sensor circuits
  • Communication modules
  • Embedded control systems

Stable power delivery helps prevent false debugging results caused by unstable voltage supply.

5. Safe Testing with OVP & OCP Protection

Sensitive embedded circuits require reliable protection.

The MPS-305QC includes:

Over Voltage Protection (OVP)

Protects:

  • MCU chips
  • Sensors
  • Communication modules
  • Prototype boards

from accidental over-voltage input.

Over Current Protection (OCP)

Helps prevent damage caused by:

  • PCB short circuits
  • Incorrect wiring
  • Component failures

6. Output ON/OFF Control for Efficient Debugging

The independent OUTPUT button allows engineers to:

  • Enable power after checking settings
  • Quickly restart test conditions
  • Safely connect and disconnect prototype boards

Ideal for repeated debugging cycles.

7. Panel Lock for Long-Term Testing

During extended power consumption testing, accidental parameter changes can interrupt experiments.

The LOCK function prevents:

  • Unwanted voltage adjustment
  • Incorrect operation
  • Testing interruption

Suitable for:

  • Overnight MCU current monitoring
  • Long-term stability testing
  • Laboratory experiments

8. USB-A & USB-C Power Analysis

Built-in USB testing interfaces provide additional diagnostic capability.

USB-A QC Testing

Supports:

  • Fast charging analysis
  • USB power verification

USB-C PD Testing

Helps analyze:

  • PD charging performance
  • USB-C power negotiation
  • Portable device power issues

9. Compact Bench Power Solution for Electronics Engineers

With a compact design, the MPS-305QC fits easily into:

  • Embedded development labs
  • PCB repair stations
  • Electronics workshops
  • University laboratories

It combines:

  • Adjustable DC power supply
  • Current monitoring
  • USB testing functions
  • Circuit protection

into one practical workstation tool.
