1. Performance Testing
1.1 Output Stability Testing
We conducted extended load testing on the power adapter under multiple voltage and current load conditions. Results are as follows:
No-Load Test: Without any load, the adapter maintained output voltage within ±1% of the rated value, demonstrating exceptional voltage stability.
Full Load Test: Under maximum load (5A), voltage output remains stable with fluctuations controlled within ±2%, fully meeting industrial standards.
Overload Protection: During testing, we subjected the adapter to a slight overload. The built-in overload protection mechanism automatically cuts off the current, ensuring safe operation of the device.
1.2 Thermal Stability Test
The heat dissipation design of the adapter is critical, especially during prolonged high-load operation. After a continuous 6-hour full-load test, the temperature remained below the design threshold (60°C). Its integrated thermal control system and high-efficiency heat dissipation materials effectively prevent overheating, ensuring stable long-term operation.
1.3 Efficiency Testing
Per international energy efficiency standards (Energy Star), the XXX power adapter maintains conversion efficiency above 93% at loads exceeding 50%, significantly reducing energy waste and meeting environmental requirements. High efficiency also translates to lower power consumption and reduced heat generation, enhancing overall product reliability and lifespan.
2. Safety Evaluation
2.1 Short-Circuit Protection
Short-circuit testing demonstrated that the adapter rapidly cuts off current and activates protective mechanisms upon encountering a short circuit, effectively preventing damage to the adapter itself or connected devices. This process requires no manual intervention and automatically resumes normal operation.
2.2 Overvoltage Protection
The adapter incorporates built-in overvoltage protection circuitry. Testing confirms that even when input voltage exceeds the rated value by 20%, the adapter automatically disconnects output within the specified timeframe, preventing device damage from overvoltage.
2.3 Fire Prevention Design
Constructed with high-temperature-resistant and flame-retardant materials, the adapter housing maintains structural integrity and prevents deformation or melting during high-temperature testing. It preserves insulation properties even under prolonged high-load operation, eliminating electrical fire hazards.
3. Product Appearance and Design
3.1 Dimensions and Weight
