THE PULSE OF THE FUTURE P V X - 2 11 0 2 0 0 V 5 0 A P U L S E G E N E R AT O R • • • • • • • • The PVX-2110 high power pulse generator (pulsed voltage source) is designed for pulsing low impedance loads (from 1Ω to 25Ω) 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, semiconductor testing and characterization, and other test and measurement and R&D applications. The PVX-2110 requires a TTL gate signal and high voltage DC power 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 supply. The PVX-2110 features front panel indicator LEDs to monitor the status of the pulse generator. Front panel voltage and current monitors provide a straightforward means to view the output voltage and current waveforms in realtime, eliminating the need for an external high voltage oscilloscope probe. 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 1Ω Ω to 25Ω Ω 5Ω. 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 damage due to over-current conditions such as arcs and shorts in the load or interconnect cable. If an over-current condition is detected, the output pulse is truncated for 10 milliseconds. The pulse generator then automatically reenables 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 solidstate 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, impedancematching 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. The output cable supplied with the unit is an innovative custom designed multi-coaxial cable with an impedance of DIRECTED ENERGY INCORPORATED THE PULSE OF THE FUTURE SPECIFICATIONS (All specifications measured into a 5Ω load connected with 4 feet (~1.2M) 5Ω cable provided with the PVX-2110) OUTPUT Output Voltage Polarity Positive Or Negative, Factory Configured Maximum Value 200 Volts Minimum Value 0 Volts Means Of Adjustment Controlled By Power Supply Input Voltage Maximum Output Current 50A Peak, 25A Average (1) Pulse Rise And Fall Time <100ns (10% to 90%) Pulse Width <200ns to 2ms, Controlled by Input Gate Pulse Recurrence Frequency (PRF) Max.

Peak output power is defined as V x I during the output pulse. Average output power is defined as V x I x Duty Cycle. Input DC power supply must be the same polarity as the PVX-2110 (i.e. a positive output PVX-2110 requires a positive high voltage DC input).
