13 , leaving the display pulse voltage waveform on the oscilloscope a pulse current waveform of the BNC connector;

14. With pulse voltage and current sampling and holding circuit, it can be sent to the central control via RS232 / RS485 through PLC ;

15. Turn off the high-voltage DC power supply and pulse output when the power fails .

16 , a timing signal by the through fiber sent in the control, there are the timing signals green light is flashing on.

17. The touch screen is used for local operation control and status display of the power supply , including: ( 1 ) startup, shutdown, reset , magnetron voltage setting, magnetron pulse current setting , magnetron filament current setting ; (1) 2 ) Pulse voltage value display , magnetron pulse current display, magnetron filament current display, working status display ; ( 3 ) Pulse overcurrent, overtemperature, pulse enable signal, green is normal, red is fault. (4) You can set the serial port baud rate

18 , with anti-interference ability, long-term stable and reliable work;

19 , reasonable power structure, facilitating debugging, testing and maintenance;

20 , the analog signal and the switching signal are routed separately;

21 , the function of the interface with the central control :

Note: The serial port control can set the baud rate. There are two interfaces: RS232 and RS485.

( 1 ) Timing signal: HFBR-2412, 2 (high voltage output / sampling and holding) optical ports (from Central Control)

( 2 ) Filament current setting; RS232 / RS485

( 3 ) Filament current readback; RS232 / RS485

( 4 ) Magnetron current setting ; RS232 / RS485

( 5 ) Magnetron current readback ; RS232 / RS485

( 6 ) Magnetron voltage setting ; RS232 / RS485

( 7 ) Magnetron voltage mining ; RS232 / RS485

( 8 ) Pulse voltage mining of magnetron ; RS232 / RS485

( 9 ) Local remote control switch; RS232 / RS485

( 10 ) Remote control switch setting and readback; RS232 / RS485

( 11 ) Remote control high voltage startup setting and readback; RS232 / RS485

( 12 ) Pulse enable ; RS232 / RS485

( 13 ) Vacuum interlock input : contact, normally closed , BNC (from central control)

( 14 ) Reading of vacuum interlocking status : RS232 / RS485

( 15 ) MPS input : contact, normally closed , BNC (from central control)

( 16 ) MPS status reading : RS232 / RS485

( 17 ) Remote control reset: RS232 / RS485

( 18 ) High voltage plus: RS232 / RS485

( 19 ) Power failure: DC over current, over voltage, over temperature, turn off DC high voltage output. RS232 / RS485

( 20 ) Pulse overcurrent: After the pulse current exceeds the threshold set by the internal point, the high-voltage pulse output is stopped , the high-voltage power supply is turned off, and a fault signal is sent . RS232 / RS485

( 21 ) Recovery : power failure must be manually through a control panel or a remote control interface intervention to restore; pulse overcurrent fault can be set manually restore and automatic recovery , ( manual recovery is manually by screen or a remote control interface control intervention to restore; Automatic recovery is to resume normal work after a delay of 5s or a remotely set time after a failure occurs . ) RS232 / RS485, consulting on BNCT magnetron high voltage power supply technology Xi'an Zhaofu Electronics Co., Ltd. !
