The new power supply for the IBM Lenovo Mitsu laptop is equipped with a ferrite filter and excellent protection against overvoltage, overheating, overload and overcharging. Lenovo's IBM laptop chargers are aimed at the most demanding users who value stress-free and comfortable work. The quality of the product is evidenced by the obtained certificates: CE, ROHS, FCC and strict quality control eliminating the occurrence of possible defects.
QUALITY FIRST
- Temperature resistance - The influence of high and low temperatures on the resistance of protection systems and electrical parameters of the power supply is being studied.
- Electrical test - Testing the correctness of electrical connections between individual components of the power supply.
- Short-circuit and surge test - The reaction of the power supply protection systems as a result of a short circuit and a sudden voltage surge simulated by feeding a high-voltage pulse at the input of the power supply is tested.
- Final Test - The output voltage level of the power supply is tested by subjecting it to an hour-long, continuous load.
