The new Mitsu power supply for IBM Lenovo laptop is equipped with a ferrite filter and excellent protection against overvoltage, overheat, overload and overcharge. IBM Lenovo laptop chargers are designed for the most demanding users who value stress-free and convenient work. The quality of the product is confirmed by the following certificates: CE, ROHS, FCC and strict quality control, eliminating possible defects. QUALITY FIRST Temperature resistance - The influence of high and low temperatures on the resistances of protection systems and the electrical parameters of the power supply is checked. Electrical test - checking the correctness of the electrical connections between the individual components of the power supply. Short-circuit and overvoltage test - the response of the power supply protection systems to short-circuit and sudden voltage surges simulated by providing a high-voltage pulse at the input of the power supply is tested. Final test - The output voltage level of the power supply is checked by running for one hour under constant load.
