Almost all PVX Series high-voltage pulsers require an external high-voltage power supply. The single exception is the PVX-4000-2kV-Int, which has an integrated internal high-voltage source. For all other models — including the PVX-4110, PVX-4130, PVX-4140, PVX-4150, and PVX-4170 — you will need a separate DC power supply rated to the pulser’s input voltage specification. Berkeley Nucleonics offers the Heinzinger EVO Series as a matched power supply for PVX pulsers, and can recommend the right combination for your application.
