E Beam Power Supply

Applications

Electron beam applications & X-Ray.

Typical Parameters

EB04-220Vac-N1200-120-F30-B400

Output voltage: 120 kV
Output current: 10mA
Filament voltage: 30 V
Filament current: 20 A
Grid bias voltage: – 400 V
Grid bias current: 20mA
This machine contains grid bias of +400V. Positive and negative grid bias switchable.

Controls

There is a red emergency stop button, green power switch and status indicator on the front panel.
The high voltage can be shut down immediately by pressing the red emergency stop button. Rotate the button clockwise, then the button will reset and cancel interlock for high voltage. The green power switch is used to switch on/off main power source. The status indicator shows the working status of the power switch, constant voltage or current status, overvoltage alarm, overcurrent alarm for filament, chain reaction and discharging prompt.

Control Interface

There are three interfaces on the rear panel of the power supply, J1, J2 and J3.
J1 is for DB9, 485 port, which is used to communicate with the computer to control the operating mode.
J2 is DB50, analogue signal transmission port for connection with remote controller.
J3 is RJ45 port and is not available for this machine.

(Wiring B)

HV Interface

Three-core cable, industrial standard HV connector R24 socket and corresponding cable connectors are integrated. Maximum filament current is up to 20A. Output of three-core cable: one for common, one for filament, and one for grid bias. Especially suitable for applications with large filament current.

Parameter Settings

All output parameters can have an analog value from 0V to 10V for remote setting.
High voltage 0V to 10V refers to 0kV to -120 kV.
Filament voltage 0V to 10V refers to 0A to 20A.
Grid bias 0V to 10V refers to 0V to -400V.

Dimensions & Case Material

7U to 11U .
Aluminium alloy shell.

Safety

This power supply contains high voltages and power. Contact with the output may result in fatal injury. It should only be used and maintained by trained personnel.

Before opening the power supply, please check following:
1. Whether the power supply and its environment is clean and dry;
2. Whether there are irrelevant items nearby the output or load of high voltage;
3. Make sure the return current from the load is well grounded via the grounding bolt at the back.

Definitions DB50

Note: All error signals are low level. Refer to DGND.
PLC set signal is 0- 10Vdc, where 0 refers to the maximum. Refer to AGND.
For all switching signals, 0v refers to on, suspend or high level refers to off. Refer to DGND.
