Function
The high-voltage power supply unit produces high voltage for an
electron beam vaporizer that is incorporated in a vacuum device.
The maximum power output of the unit is 3, 5, 6, 10 odr
12 kW.
The operation range of high voltage is from 4kV to 10kV, the
range of emission current is 0-1200 mA The set values are
maintained constant independently of the acceptable mains
fluctuation of –10/+10 %.
High voltage and emission current are set with the use of
connected control devices. Data are exchanged between the
high-voltage power supply unit and the control unit via connected
control lines.
All electric connections, i.e.
- connection to the mains;
- connection to the control unit;
- earthing; and
- high-voltage output
are made on the rear panel of the device.
To ensure protection from faulty operation the high-voltage power
supply unit is equipped with safety current circuits that disconnect
high voltage immediately in case of a failure. Failures are
indicated with the use of the LED display. The primary purpose of
the safety circuits is to protect the operation personnel, but they
also protect the whole system from consequences of faulty
operation.
The inside of the high-voltage power supply unit is cooled with air.
Generated heat is removed with the use of an internal fan.
The high-voltage power supply unit is designed for installation in
a 19” rack.
