General Information
The NSP series of power supplies are nanosecond pulsers with an output voltage range of 0-30 kV, pulse
widths of 20-500 ns, and pulse repetition frequencies up to 30 kHz. Each parameter is independently
adjustable through a continuous range, although not all the maximum parameters may be reached
simultaneously, depending on the load that is being driven. The NSP series units are designed to drive
dielectric barrier discharges, pseudosparks, arcs, and other loads where impedance matching is
challenging.
The NSP series comes with either a floating output or a grounded output. The floating output stage (on
part numbers ending in –F) allows the user complete control over the current return path, minimizing EMI
noise, and enhancing laboratory safety. EHT recommends using the floating configuration whenever
possible. However, the floating output units may not be used with a grounded load. In applications where
the load is grounded, the grounded output version of the NSP must be used. Grounded NSP power
supplies come in both a positive polarity (part numbers ending in –P) and a negative polarity (part
numbers ending in –N) output variant.
NSP series power supplies can be operated in three modes: free-running, triggered, and external. Free-
running mode is useful when the NSP is being used as part of a standalone benchtop experiment, it will
continuously output pulses of the specified pulse width and frequency. Triggered mode is useful for
synchronization with other equipment – the pulse width is set by the front panel knobs, while the output is
triggered remotely through a fiber-optically isolated input. Lastly, External mode allows full remote
control, where both the pulse width and trigger timing are controlled by a user’s signal generator or
control system, which can be useful if pulse width must be modulated from pulse to pulse.
