the pulse of the future directed energy incorporated PVX-2110 200v 50a pulse generator ? 0 to 200v pulse output ? 10kw peak output power ? <100ns rise and fall times ? <200ns to 2ms pulse width ? 0 to 50khz pulse repetition frequency ? protected against arcs, shorts and load transients ? integral voltage and current monitor outputs ? optimized to drive loads from 1 ? ? ? ? to 25 ? ? ? ? the PVX-2110 high power pulse generator (pulsed volt- age source) is designed for pulsing low impedance loads (from 1 ? to 25 ?) at up to 200v and 50a, with pulse widths from 200ns to 2ms . the exceptional pulse fidelity of the PVX-2110 will optimize the performance of any system in which it is used. the PVX-2110 can deliver up to 10kw of peak output power and 5kw of average output power, making it well suited for use in materials testing and processing, semi- conductor testing and characterization, and other test and measurement and r&d applications. the PVX-2110 requires a ttl gate signal and high volt- age dc power supply inputs. the output pulse width and frequency are controlled by the gate signal. the pulse out- put voltage is controlled by the amplitude of the input dc power supply. the PVX-2110 features front panel indicator leds to monitor the status of the pulse generator. front panel volt- age and current monitors provide a straightforward means to view the output voltage and current waveforms in real- time, eliminating the need for an external high voltage os- cilloscope probe. the output cable supplied with the unit is an innovative custom designed multi-coaxial cable with an impedance of 5 ?. the design of this cable maintains the fidelity of the output pulse without introducing pulse distortion or ringing, and provides a convenient means of connecting the pulse generator to the load. the PVX-2110 has over-current detection and shut-down circuitry to protect the pulse generator from potential dam- age due to over-current conditions such as arcs and shorts in the load or interconnect cable. if an over-current condi- tion is detected, the output pulse is truncated for 10 milli- seconds. the pulse generator then automatically re- enables the output, and will continue pulsing, unless the over-current condition persists. it is also protected against operation at excessive pulse widths or frequencies. the pulse generator is a direct-coupled, air-cooled solid- state design, offering fast pulse rise and fall times, low power dissipation, and virtually no over-shoot, under-shoot or ringing. all control and protection logic circuitry, support power, energy storage and output network are incorporated into the PVX-2110. it is connected directly to the load, and does not require series or shunt resistors, impedance- matching networks between the pulse generator and the load, or additional energy storage (capacitor banks). all of this is taken care of within the PVX-2110.
