Page 8: Electrical Specification
The minimum supply requirements are 1200VA: 1.1.3 The output voltage, current and duty cycle are as follows: Output Voltage Output Current 1 Output Current 2 KV30-40 30kV 20mA 40mA KV15-80 15kV 40mA 80mA Output current 1 is the continuous current rating. -
Page 9: Output Voltage Control
Output Voltage Control 1.2.1 The output is controlled from zero by means of a regulating transformer. The transformer is operated by means of a control knob which is located on the front panel of the control unit. To increase the output voltage the knob is turned in a clockwise direction. -
Page 10: Overload Protection
Overload Protection 1.3.1 The equipment is fitted with fixed and variable overload protection circuits as standard. 1.3.2 Fixed overload The fixed overload protection system senses any rapid increase in the load current which exceeds approximately 120% of the full load current in the high voltage circuit. The circuit will respond more quickly to low impedance faults. -
Page 11: Metering
Metering 1.4.1 The equipment is provided with the following metering: A moving coil dual range kilovoltmeter monitoring the output voltage from the equipment. A moving coil single range milliammeter monitoring the secondary current of the high voltage transformer. -

- Page 18 Method of Operation 2.3. 1 Connect the equipment as described in Section 2.1. 2.3. 2 Remove the power switch operating key before connecting the equipment to the main supply. This will ensure the equipment is in the OFF position as the key is only removable in that position.
- Page 19 MAINTENANCE The switches and contactors should be occasionally examined for signs of wear and contact erosion. Badly eroded contacts should be replaced immediately. The voltage regulator should be regularly examined, particularly in respect of the brushes, in order that the latter may be replaced before excessive wear has taken place. The intervals between inspection and renewal of the brushes will depend upon the amount of usage.
