DESCRIPTION OF EQUIPMENT

1.1

Electrical Specification

Supply requirements

115V/230V 10% auto-selecting

50/60Hz

750VA maximum

Output voltage

0- 30kVdc with respect to earth

(0-60kV between outputs, centre earthed)

Output current

5mA continuous from each output

10mA from each output with a duty cycle of 5 minutes
on/15 minutes off

Current limiting (PT30-10C only)

The PT30-10C has an extra pushbutton control to limit
the output current to a maximum of 7.5mA (dependent on
the output voltage).

Output earth connection

The earthy end of the high voltage outputs is connected
to the earth system of the equipment.
