The new Mitsu brand HP Compaq notebook power supply is equipped with a ferrite filter and excellent protection against overvoltage, overheat, overload and overcharge. HP Compaq laptop chargers are designed for the most vulnerable users who value their work stress-free and convenient. The quality of the product is confirmed by the received certificates: CE, ROHS, FCC and strict quality control aimed at eliminating possible defects. QUALITY FIRST, temperature resistance. The effect of high and low temperatures on the resistance of protective systems and electrical parameters of the power source is tested. Electrical test - testing the correctness of the electrical connections between the various components of the power supply. Immunity to faults and overvoltage test - The response of the protective systems of the power supply is investigated due to a short circuit and a sudden change in voltage, simulated by applying a high voltage pulse at the input of the power supply. Final test - Tests the output voltage level of the power supply by operating it under a continuous hourly load.
