  • 4. Robust & Safe Design
  • Aluminum Alloy Housing：Effective heat dissipation for 24/7 continuous operation, suitable for high-duty cycles in production lines.
  • Overvoltage/Overcurrent/Overtemperature Protection：Automatically shuts down to prevent damage to DUTs (Devices Under Test) and operators, compliant with IEC 61010 safety standards. Application Scenarios 1. Power Supply Manufacturing & QA
  • Production Line Testing：Verify voltage stability, load regulation, and transient response of AC/DC adapters, switching power supplies, and inverters (widely used by electronics manufacturers in Germany, the US, etc.).
  • Certification Compliance：Supports testing per UL, CE, and IEC standards, ensuring products meet EU/US market access requirements.
  • 2. Battery & Energy Storage Testing
  • EV Battery Modules：Simulate discharge/charge cycles to evaluate capacity, internal resistance, and lifespan (critical for electric vehicle R&D labs in Europe).
  • Consumer Electronics Batteries：Test smartphone, laptop, and drone batteries for overcurrent protection and charging efficiency (popular among US repair shops and startups).
  • 3. Industrial & Laboratory R&D
  • Circuit Design Validation：Test PCB power management systems under various load conditions to optimize energy efficiency (used in university labs and tech hubs like Silicon Valley).
  • Renewable Energy Systems：Evaluate performance of solar inverters and wind turbine converters by simulating grid load fluctuations (aligns with Europe’s green energy transition policies).
  • 4. Electronic Repair & Maintenance
  • Troubleshooting Power Issues：Diagnose faulty power supplies in medical equipment, industrial machinery, and AV devices (essential for repair centers in the US and Western Europe).
