　　Meet the requirements of China's national military standard GJB 181A-2003 Aircraft Power Supply Features

　　Compliance with civil aviation industry standardMH/T 6018-1999 Ground static power supply requirements

　　Many specifications

　　The output voltage is 28.5V,the output current is 50 to 2000A

　　Five new

　　New electronic components,new electromagnetic materials,new transformation technologies,new control theories,new functions

　　Five highs

　　High frequency,high efficiency,high power density,high power factor and high reliability

　　High-precision,low ripple

　　The DC power supply is controlled by peak current,with fast response and high output regulator accuracy.At the same time,the output is equipped with a multi-stage filter,EMI/EMC meets EN61000-6-3,EN61000-6-1,and the output ripple is low.

　　High efficiency

　　A wide range of soft switch technology enables high power supply efficiency and low noise,and the efficiency of the entire machine is up to 95%(under load of 100%).

　　Small size and light weight

　　Due to the use of soft switch transformation technology,the internal radiator is greatly reduced,the whole machine volume than the hard switch regulated power supply is smaller and more reliable,lighter weight,high power density,can meet the special needs of many military equipment.

　　High reliability

　　With input phase-out protection,short-circuit protection,overload protection,overvoltage protection,overcurrent protection and independent temperature detection protection circuits and special design for high reliability of military power supplies.

　　Far-end measurement

　　The far-end measurement function can be used to compensate for the voltage drop between the output terminal and the load.

　　OVP overvoltage protection

　　The OVP overvoltage protection function is standard and any value srated from 3V to 110%can be pre-set as the PROTECTION value of OVP.

　　Short-circuit protection

　　A long short circuit is allowed under certain conditions.

　　Overload protection

　　The power supply has an overload protection circuit inside to prevent damage to the power supply due to overload.

　　Overheat protection

　　Automatic shutdown with no output when the power supply is overheated,and the device automatically resumes output at low temperatures.

　　Output display

　　Voltage and current are displayed using high-precision LED digital meters.

　　Intelligent

　　Can be connected to the computer,forming a computer-controlled intelligent power supply(optional).
