KUAIQU KQ7901 Automated Test Power Supply, 4.3-Inch TFT Programmable DC Source with List Sequence Control, Remote Sensing & Digital Interfaces

Description

The KUAIQU KQ7901 Automated Test Power Supply is designed for repeatable electrical verification, production line inspection, and computer-integrated test systems. Its 4.3-inch TFT color display, five-digit voltage and current readouts, and real-time power monitoring give operators a clear view of output conditions throughout the testing process.

Featuring programmable List sequences, USB-based test data import, 100 parameter memory groups, and USB, RS232, and RS485 communication interfaces, this programmable test power source helps streamline recurring test procedures and reduce manual setup. Remote Sense compensation, OCP and OVP protection, reverse-polarity protection, and panel locking make the KQ7901 a practical solution for electronic manufacturing, functional verification, and automated electrical test stations.

Key Features

1. Clear Digital Monitoring for Test Stations

The five-digit voltage and current displays, together with real-time power readings, help operators monitor supply conditions during automated electrical verification. Encoder adjustment and direct numeric keypad entry make it easier to configure test parameters accurately and repeat established procedures across multiple test runs.

2. 4.3-Inch TFT Interface for Efficient Test Operation

The full-color TFT screen presents operating parameters and curve information in an accessible interface. Adjustable brightness supports different production and laboratory environments, while Chinese and English language switching accommodates multilingual test teams.

3. Simultaneous Parameter Curve Monitoring

The curve interface can display two parameters simultaneously from voltage, current, and power. This visual feedback helps operators observe changes in output behavior during functional verification, troubleshooting, and electrical performance evaluation.

4. 100 Test Parameter Memory Groups

Store and recall up to 100 groups of settings, including voltage, current, OCP thresholds, and OVP thresholds. These presets help standardize recurring inspection tasks, shorten configuration time, and reduce the likelihood of manual parameter entry errors in production testing workflows.

5. Programmable List Sequences for Repeatable Testing

The KQ7901 supports local List programming and test data import from a USB drive. Predefined output sequences can be prepared for repeatable electrical checks and multi-step verification procedures, helping integrate programmable power delivery into structured testing workflows.

List sequence timing, step count, and transition behavior should be confirmed against the instrument specifications before designing a production test procedure.

6. Multiple Interfaces for Test System Integration

USB, RS232, and RS485 interfaces support computer communication and integration into compatible test setups. These interfaces make the KQ7901 suitable for computer-coordinated power delivery, test station configuration, and repeated measurement procedures when used with compatible software and communication commands.

7. Remote Sense Compensation for More Reliable Voltage Delivery

Remote Sense compensation helps offset voltage drops in output leads by sensing voltage at the load connection. This feature is useful when cable resistance affects the voltage delivered to the device under test. Correct Sense wiring and compliance with the instrument's operating limits are essential.

8. Reverse-Polarity Protection with Connection Alerts

Built-in battery reverse-polarity protection provides an alert when an incorrect battery connection is detected. This feature helps operators identify wiring errors during applicable battery-related electrical checks and reduces the risk of connection mistakes.

9. USB-A and USB-C Auxiliary Power Outputs

Dedicated USB-A and USB-C fast-charging outputs provide convenient power for compatible accessories and USB-powered devices used around the test station. Real-time output monitoring helps users observe the auxiliary output status without relying solely on external indicators.

10. Constant-Voltage Operation and Output Protection

Forced constant-voltage mode is designed to maintain CV operation under the instrument's specified conditions. Overcurrent protection (OCP), overvoltage protection (OVP), and panel locking add safeguards against excessive output conditions and unintended setting changes during unattended or repetitive test workflows.

Applications

Automated Production Line Inspection

Use the KQ7901 as a programmable source in electronic manufacturing test stations that require consistent supply settings for recurring product checks.

Electronic Assembly Functional Verification

Provide controlled DC power to electronic assemblies, interface boards, and control modules during functional inspection and troubleshooting.

Test Fixture and ATE Integration

Integrate the instrument into compatible automated test equipment (ATE) and computer-coordinated test fixtures through supported communication interfaces for programmable power delivery.

Power Module Verification

Support functional checks of voltage regulators, DC-DC converter boards, and power management assemblies as part of a broader test setup. Additional instruments may be required for load regulation, efficiency, ripple, and transient-response measurements.

Quality Control and Incoming Inspection

Use stored parameter groups to standardize repeatable electrical checks during incoming component inspection, production quality control, and final functional verification.

Battery Protection Circuit Inspection

Supply controlled power to compatible battery management and protection electronics during functional checks. Verify voltage, current, polarity, and test requirements before connecting any battery cells.
