Electrical Specification

1.1.1

The supply voltage will be as follows:

220/240V 1 phase 50/60Hz+10%
115V 1 phase 50/60Hz +10% -6%

1.1.2

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.

Output current 2

is based on a duty cycle of 5 minutes ON load followed
by 15 minutes OFF load.

1.1.4

One side of the high voltage transformer output is connected to the earth system of
the equipment.

1.1.5

System Interlock:

The equipment is fitted with a zero volt interlock system on the controlling regulator.
This interlock prevents the output being energised unless the controlling regulator is in
the minimum output position.

 

1.1.6

An earthing hook is provided which is stored in the lid of the test set.
