The automatic power supply testing system is professional and efficient. It helps enterprises reduce power supply testing costs and improve production efficiency
1. High degree of automation enhances testing efficiency
Automatically execute the test process: Through preset programs, automatically complete tests on input/output characteristics, protection functions, energy efficiency, etc., reducing manual operation time.
Multi-channel parallel testing: Supports simultaneous testing of multiple power supply samples, significantly shortening the batch testing cycle (such as full inspection of fast charging power sources on the production line).
7× 24-hour continuous operation: Suitable for scenarios such as aging tests and life tests, no manual intervention is required.
2. High testing accuracy and traceable data
Accurately measure key parameters:
Voltage/current accuracy: Up to 0.1% range accuracy (such as output from a 5V/1A adapter).
Ripple noise: Resolution up to 1mVpp (oscilloscope-level measurement).
Energy efficiency test: The error of the power analyzer is <0.5% (meeting the DoE/ Energy Star standard).
Eliminate human errors: Automate data collection to avoid deviations from manual reading or recording.
Data storage and traceability: Test results are automatically generated into Excel/PDF reports, supporting barcode scanning to associate sample information.
3. Cover all test items
Basic performance test:
Input voltage range (such as 90V to 264VAC), inrush current, no-load power consumption.
Output voltage/current stability, load regulation rate, dynamic response.
Verification of protection function
The protection mechanisms such as overvoltage (OVP), overcurrent (OCP), short circuit (SCP), and over-temperature (OTP) are triggered for testing.
Environmental adaptability test
Simulation of extreme conditions such as high and low temperatures (-40℃ to +85℃), humidity and heat (95% RH), vibration/shock, etc.
Special scenario testing
Fast charging protocol compatibility (PD3.0/QC4.0/PPS), audio noise, electromagnetic compatibility (EMC), etc.
4. Safety and reliability guarantee
Isolation Design and Protection
The high-voltage test section adopts electrical isolation to avoid operational risks (such as leakage current <1mA during withstand voltage testing).
The output is automatically cut off during short-circuit/overload testing to protect the equipment and samples.
Abnormal alarm and log
Real-time monitoring of the test status, over-limit alarm and recording of abnormal events (such as excessively high temperature and sudden voltage changes).
Long-term stability
It is suitable for aging tests (such as 1000 hours of full-load operation) to expose potential faults in advance.
5. Comply with global certification standards
Preset compliance test template:
Safety standards: IEC 62368-1, UL 60065, GB 4943, etc.
Energy efficiency standards: DoE Level VI, Energy Star, EU ErP Directive.
EMC standards: CISPR 32, EN 55024.
Quickly generate certification reports:
Directly output the test data that meets the certification requirements (such as THD harmonic content, standby power consumption).
6. Reduce the overall cost
Labor cost savings
Replace the manual item-by-item testing and reduce the human input in the production line (such as the full inspection of the automated production line replacing sampling inspection).
Hardware resource reuse
The modular design supports the expansion of testing functions (such as adding a fast charging protocol analysis module).
Integrate with ATE (Automated Test Equipment) to achieve fully unmanned testing throughout the entire process.
Quality cost optimization
Early detection of design flaws (such as iterative testing during the R&D stage) can prevent recall losses after mass production.
7. Intelligence and remote management
Software Control and Data Analysis
The test parameters are set through a graphical interface, and script programming (such as Python/LabVIEW) is supported.
Intelligent reports such as data trend analysis, pass rate statistics, and fault distribution maps.
Remote monitoring and maintenance
The test progress can be monitored in real time through the local area network/cloud, and remote fault diagnosis is supported.
