Quality first
- Thermal resistance - examines the effect of high and low temperatures on the durability of protective circuits and the power supply’s electrical performance.
- Electrical test - verifies the correctness of electrical connections between individual components of the power supply.
- Short-circuit and overvoltage test - checks the response of the power supply’s protection systems to a short circuit and sudden overvoltage simulated by applying a high-voltage pulse to the power supply input.
- Final test - tests the output voltage level of the power supply under one hour of continuous load.
