Power Supply SONY 19.5V 4.7A ZM/SON19547 Mitsu's new laptop power supply Sony has a ferrite filter and excellent protection against overvoltage, overheat, overload and overcharge. Sony 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. 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. The set includes a power cord, warranty card and user manual How to choose the right power source? DC (Direct Current Direct Current) power settings are usually found under the laptop on a sticker after the word INPUT. The V (volts) of the power supply must match the value indicated on the laptop. Current A (amps) is equal to or greater than the value specified by the laptop, this parameter represents the maximum current with which the power supply can be loaded, the size of the load is determined by the laptop Power W (watts) is the result of multiplying the voltage and the current Plug shape and size - compare with the proposed product image and the dimensions of the plug specified in the description; we can also determine from the database of the power source manufacturer
