Voltage Multiplier Assembly
These series connected disc capacitors have been developed for use in low power voltage multipliers for high voltage DC generators. These devices find their major application in the manufacture of voltage multipliers for electrostatic paint spraying equipment and their compact form lends itself to their incorporation in hand held electrostatic spray guns.
A number of capacitors are assembled together with intermediate fittings which allow the connection of diodes to be made. Output voltages in excess of 100kVDC can be produced depending on the number of stages.
Voltage ratings of individual discs range from 8 to 1 5kVDC assuming that the quality of encapsulation by the user is sufficient to prevent external breakdown.
A variety of intermediate metal fittings are available and the number of individual capacitors in each stack can be varied to meet customers requirements up to a maximum of 12.
