The power supply for the Mitsu Dell laptop is equipped with a ferrite filter and excellent protection against overvoltage, overheating, overload and overcharging. Dell laptop chargers are aimed at the most demanding users, who appreciate stress-free and comfortable work. The quality of the product is confirmed by the following certificates: CE, ROHS, FCC and strict quality control eliminating possible defects.

QUALITY BEFORE EVERYTHING

• Temperature resistance - The influence of high and low temperatures on the resistance of the protection systems and the electrical parameters of the PSU is tested.
• Electrical test - Testing the correctness of electrical connections between individual components of the PSU.
• Short-circuit and over-voltage test - The reaction of the PSU protection systems due to a short circuit and a sudden voltage jump simulated by supplying a high-voltage pulse at the input of the PSU is tested.
• Final test - The output voltage level of the UPS is tested by subjecting it to an hour-long continuous load.
