The PVM-4150 is a compact, OEM-style pulse generator module producing fast, high voltage wave forms to 1,500V. Optimized for driving high impedance capacitive loads, the PVM-4150 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. The exceptional pulse fidelity of the PVM-4150 will optimize the performance of any system in which it is used. The PVM-4150 will generate an output voltage pulse of 1500 volts with rise and fall times less than 25ns, with very flat voltage pulses to DC into a capacitive load. It can generate singled-ended output pulses from ground to +1500V or from ground to -1500V, and can also generate pulses originating from a DC voltage offset from ground by using both VLow and VHigh power supply inputs. The PVM-4150 requires user-supplied +24VDC to +28VDC support power, a TTL gate signal, a high voltage DC power supply and optional DC offset supply inputs. The output pulse width and frequency are controlled by the gate signal. The pulse output voltage is controlled by the amplitude of the input DC power supplies. The pulser is a half-bridge (totem pole) design, offering equally fast pulse rise and fall times, low power dissipation, and virtually no over-shoot, under-shoot or ringing. The PVM-4150 has over-current detection and shut-down circuitry to protect the pulse generator from potential damage due to arcs and shorts in the load or interconnect cable.
