Optimized for driving high impedance capacitive loads at up to ±2000 V, the PVX-4000-2kV is well-suited for driving extraction grids and deflection plates for electrostatic modulation of particle beams in time-of-flight mass spectrometers and accelerators. The PVX-4000-2kV-EX requires external high-voltage power supply sources from 0 V to ±2000 V. For example, a +1000 V supply can be connected to the positive voltage input, and a -1000 V supply can be connected to the negative voltage input, for a total of 2000 V. The differential voltage (difference between the positive and negative supply voltages) must not exceed 2000 V. The system is capable of duty cycles from 2% to 98% and repetition rates from 40 Hz to 30,000 Hz using the internal trigger. With an external trigger the system is capable of single shot to 600 kHz with a pulse width of 500 ns to 100% duty cycle. Programming is done through front panel controls as well as RS-232 and USB computer interfaces. Computer Interfaces For automated applications, complete control of the instrument is provided through RS-232 and USB computer interfaces. Up to five system configurations may be stored in internal non-volatile memory, providing instant recall of frequently-used configurations. Control Signals Conveniently-located front panel BNC connectors allow the PVX-4000-2kV to be externally triggered. The system has a Sync output for interconnection to other equipment. The pulse from the Sync output is synchronized to the leading edge of the output voltage pulse. The output voltage waveform can easily be monitored through the Voltage Monitor BNC connection using an oscilloscope set to 1 MΩ termination. Features 0 to ±2000V Pulse Output <50ns Rise And Fall Times Pulse widths from <500ns to DC Internal Trigger 40Hz to 30KHz Pulse Repetition Frequency 2% to 98% Duty Cycle External Trigger Single Shot to 600KHz Pulse Repetition Frequency 0% to 100% Duty Cycle Protected Against Arcs, Shorts And Load Transients Voltage Monitor and Sync Outputs Applications Optimized for high impedance capacitive loads, the PVX-4000-2kV-EX is well-suited for driving extraction grids and deflection plates for electrostatic modulation of particle beams in time-of-flight mass spectrometers and accelerators. Its robust and versatile design also makes it well suited for pulsing or gating power tube grids, Pockels cells and Q Switches, acoustic transducers, microchannel plates, photomultiplier tubes and image intensifiers.

35. Solutions to Common Problems
 Problem: Fault LED on or flashing.
 Solutions:
 1) Make sure the Enable connector is in place.
 2) Is the airflow blocked? Overheating?
 Problem: Output voltage is below external High Voltage supplies setpoint.
 Solutions:
 1) Make sure you are operating within the SOA? Remember to account for the cable capacitance
in your load calculation.
 2) Increase the current setting on your High Voltage Power Supply.
Internal testing used 3kV supply with 1.7A current capability.
DEI recommends a HVPS with at least 1A current capability.
