DC linear power supply characteristics
The DC linear power supply is used for the working current of the aircraft, or the maintenance power of the base station, and the input power simulation experiment of the aviation equipment, and has a wide range of applications.
DC linear power supply characteristics
■The output voltage can be adjusted from zero volts; the output current can be preset from zero.
■Easy to adjust voltage and current.
■The use of constant voltage and constant current can be automatically cross-converted to maintain the characteristics of both control and protection;
■High voltage regulation accuracy and low ripple voltage.
■With over-voltage, over-current, over-temperature and short-circuit protection functions.
DC Linear Power Applications
■Industrial and mining enterprises, scientific research institutes, research institutes, factories, laboratories and automation equipment;
■Provide aircraft for working current use, or base station maintenance power supply, and input power simulation experiment for aviation equipment;
■ Purely inductive equipment (such as motorized equipment, laser printers, photo developing equipment);
■Cold start-up of heater, constant power heating system of single crystal furnace, etc., applicable to power supply of semiconductor and single crystal growth furnace;
■Electrical equipment with large impact current, such as high impact DC starter, production test, maintenance, aircraft electric/generator/engine start, related power equipment, etc.
The cost of linear power supply is higher than that of switching power supply at a certain output power point.
Therefore, with the development and innovation of power electronics technology, switching power supply technology continues to break through and innovate. This cost problem has instead moved switching power supply technology to the low output power end, providing a wide range of development space for switching power supplies.
