3.5 kV Bipolar Pulse Generator

Available on backorder

The PVX-4140-B pulse generator is a direct coupled, air cooled, solid state half-bridge (totem pole) design, offering equally fast pulse rise and fall times, low power dissipation, and virtually no over-shoot, undershoot, or ringing. It has overcurrent detection and shutdown circuitry to protect the pulse generator from potential damage due to arcs and shorts in the load or interconnect cable.

Updating the chassis of the PVX-4140, the PVX-4140-B features integrated rack mounting, brighter and more visible front panel LEDs and a modern look and feel.

All control and protection logic, support power, energy storage, and output network circuitry is incorporated into the PVX-4140. It can be connected directly to the load, and does not require series or shunt resistors, impedance matching networks between the pulser and the load, or additional energy storage (capacitor banks). All of this is taken care of within the PVX-4140-B.

  • 0 to ±3,500 V Pulse Output
  • <25 ns Rise and Fall Times, 30 kHz Pulse Repetition Frequency
  • Protected Against Arcs, Shorts and Load Transients
  • Voltage and Current Monitor Outputs

The PVX-4140-B 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.
