SPECIFICATIONS SUBJECT TO CHANGE WITHOUT NOTICE

These specifications are measured driving a 50pF load connected with 2 feet of RG-62 cable, at

3000V output. However the PVM-4140 can drive loads of a few picofarads to several hundred

picofarads of capacitance, limited by its maximum power dissipation capability(1) . At lower load

capacitances and/or voltages less then 3000V, the PVM-4140 can operate at continuous pulse

recurrence frequencies up to 400KHz. The PVM-4140 can also drive resistive or inductive loads,

within limitations. Contact DEI for additional information and applications assistance.

(1) The power dissipated in the PVM-4140 when driving a capacitive load is defined by the for-

mula CV2F, where C is the total load capacitance, including the capacitance of the load, inter-

connect cable, and the internal capacitance of the PVM-4140, V is the pulse voltage, and F is

the pulse repetition frequency (or the total pulses per second). (For these calculations, the inter-

nal capacitance of the PVM-4140 is 120pF, and RG-62 cable is 13pf/foot.) Given the maximum

dissipation of 50W, the maximum load capacitance, frequency and/or voltage at which the PVM-

4140 can operate can be approximated using this formula. This formula also approximates the

high voltage power supply requirements needed to drive a given load at a specific voltage and

frequency. This formula is not applicable when driving resistive or inductive loads.
