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

1500V output. However the PVM-4150 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 1500V, the PVM-4150 can operate at continuous pulse

recurrence frequencies up to 1MHz. The PVM-4150 can also drive resistive or inductive loads,

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

(1) The power dissipated in the PVM-4150 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-4150, 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-4150 is 200pF, 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-

4150 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.
