the total load capacitance, including the capacitance of the load,

interconnect cable, and the internal capacitance of the PVM-4210, V

is the pulse voltage, and F is the pulse repetition frequency (or the

total pulses per second). (For these calculations, the internal ca-

pacitance of the PVM-4210 is 125pF, and Belden 8218 cable is

21.5pf/foot.) Given the maximum power supply capability of 4W

(4mA) per channel, the maximum load capacitance, frequency and/

or voltage at which the PVM-4210 can operate can be approximated

using this formula. At lower load capacitances and/or voltages less

then 950V, the PVM-4210 can operate at continuous pulse

recurrence frequencies greater than 20KHz. This formula is not

applicable when driving non-capacitive (resistive or inductive) loads.

Contact DEI for information or assistance in using the PVM-4210

with different load characteristics or impedances.
