Partner: A military unit

From 2006 to 2009, Xi'an Zhaofu Electronic Co., Ltd. developed and produced a high-voltage power source for an electron beam welding machine for a military unit, which was well received by customers. It is mainly used for the production of aerospace and aerospace equipment in conjunction with the electron beam welding machine. Until now, it works well. The specific parameters are as follows:

Input voltage: three-phase four-wire 50Hz, 380 � 10%

Output voltage: DC voltage 0 ～ -150KV continuously adjustable

Output current: DC current 0 ～ 200mA automatically changes with load

Output voltage ripple: ≤0.1%

Voltage stability: ≤0.1%

Working frequency: 20-30KHz

Overload capacity: less than 1.2 times the rated current, it can still run normally

Power efficiency: 90%

Power factor: 0.9

With over-voltage, over-current, and over-temperature protection functions, when the power supply has over-voltage, over-current, and over-temperature faults, the corresponding fault signal is reported, and the high-voltage fast-off interface is cut off: When a 24V level signal is received, it is turned off within 10us Disconnect high voltage output.
