Unique technical specifications of DC power jack

DC power jack is a special kind of power supply. The so-called special is mainly due to the technical requirements of measuring power supply are different from those of common power supply, its output voltage is particularly high, the output current is particularly large, or the requirements of stability, dynamic response and ripple are particularly high, or the voltage or current of power output need to be pulse or some other requirements. This makes the design and production of such power jack supply have more special and even stricter requirements than ordinary power jack supply.

Special power supply of DC power jack is generally designed for needs of special load or occasion. Many portable electronic products with single chip microprocessors, when the output voltage of power supply is reduced by a certain percentage due to overheating or low battery voltage, power IC would output a working state signal of power supply to single chip microprocessors to reset it. This signal can also be used to indicate the working status of the power supply (when the battery is low voltage, there is an LED display).

It has vast application, such as: electrolytic plating, anodic oxidation, induction heating, medical equipment, electric power operation, electric power test, environmental dust removal, air purification, food sterilization, laser infrared, photoelectric display, etc.
