(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
