Power supply for Acer, Packard Bell 19V 3.42A ZM/ACE19342
The new Power Supply for the Acer Mitsu laptop is equipped with a ferrite filter and excellent protection against overvoltage, overheating, overload and overcharging. Acer 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 above all:
- 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.
The set includes a power cord, warranty card and user manual.
How to choose the right power supply?
DC (direct current direct current) power supply parameters are usually given under the laptop on the sticker behind the INPUT inscription
- The voltage V (volts) of the power supply should match the value given nalaptopie
- The current intensity A (amperes) should be equal to or greater than the value given on the laptop, this parameter means the maximum current that can be loaded on the power supply, the size of the load is determined by the laptop
- Power W (watts) is the result of multiplying voltage and current
- Shape and size of the plug - please compare with the photo of the offered item and with the dimensions of the plug given in the description; we can also determine on the basis of the database of the manufacturer of power supplies
