Certification markings vary across the PVX high-voltage pulser family. The PVX-4000 series — both the PVX-4000-2kV-Int (internal power) and PVX-4000-2kV-Ext (external power) — carry CE certification. Most other PVX models, including the PVX-4110, PVX-4130, PVX-4140, and PVX-4150, do not currently carry CE, UL, or other regulatory markings. If your application requires specific certifications for compliance, contact Berkeley Nucleonics to confirm which models meet your regulatory requirements.
