The new Dell Mitsu laptop power supply features a ferrite filter and superior protection against overvoltage, overheating, overload and overcharging. Dell 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.
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 V (volt) voltage of the power supply should match the value given on the laptop
- 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
- Please compare the shape and size of the plug 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
