(1)

The power dissipated in each channel of the PVM-4210 when driving a

capacitive load is defined by the formula CV

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 capacitance 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
