SPECIFICATIONS SUBJECT TO CHANGE WITHOUT NOTICE
These specifications are measured driving a 50pF load connected with 4 feet of RG-58 cable, at
6000V output. However the PVX-4130 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 6000V, the PVX-4130 can operate at continuous pulse
recurrence frequencies above 10KHz. The PVX-4130 can also drive resistive or inductive loads,
within limitations. Contact DEI for additional information and applications assistance.
(1)
The power dissipated in the PVX-4130 when driving a capacitive load is defined by the formula CV2F, where C is the total load capacitance, including the capacitance of the load, interconnect cable, and the internal capacitance of the PVX-4130, V is the pulse voltage, and F is
the pulse repetition frequency (or the total pulses per second). (For these calculations, the internal capacitance of the PVX-4130 is 100pF, and RG-58 cable is 30pf/foot.) Given the maximum
dissipation of 100W, the maximum load capacitance, frequency and/or voltage at which the
PVX-4130 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.
