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
. 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 CV
F, 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.
