The PVX-4140 and PVX-4141 high-voltage pulsers are functionally equivalent, sharing the same electrical specifications and switching performance. The differences are mechanical: the PVX-4141 uses an updated chassis design. Current-production PVX-4140 units also include an updated front-panel PCB and remote signal interface that matches the newer PVX-4150/PVX-4151 design family. For practical purposes, both models are interchangeable…
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,…
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…
Yes, most Berkeley Nucleonics pulsed laser diode drivers offer adjustable pulse width, allowing you to tune the optical pulse duration to match your application requirements. The PCX Series drivers provide continuously variable pulse widths, typically ranging from nanoseconds to microseconds depending on the model. Some compact PCO Series modules have fixed pulse widths optimized for…
The EVO 1500-1400 and EVO 1500-1400 FLO are the same high-voltage power supply with one key difference: output grounding. The standard EVO 1500-1400 has a ground-referenced output, meaning one terminal is tied to earth ground. The FLO (floating output) version has an isolated output where neither terminal is referenced to ground. Floating output is required…
The PVX-4110 high-voltage pulser ships with the following cables and accessories: three high-voltage cables (part number 6050-0061) — two are used for high-voltage DC input connections and one for the pulsed output connection; and one 6-foot AC power cord (part number 1950-0002). No additional cables are required for basic operation, though you may need to…
The PVX-4130 high-voltage pulser ships with a checkout sheet that documents functional verification testing performed before delivery. A formal calibration certificate with traceable measurements is included with every calibration service return, and can also be requested at the time of new unit purchase at no additional charge. Berkeley Nucleonics recommends annual calibration for PVX units…
No, a single EVO Series high-voltage power supply can only deliver one output voltage at a time. Applications requiring two simultaneous voltage levels need two separate EVO units. This is because each EVO has a single regulated output stage — there is no internal switching between voltage setpoints during operation. Berkeley Nucleonics engineers can help…
No, the PVM-4210 does not include a 24 VDC power supply. The standard PVM-4210 shipment includes a control cable with D-Sub connector and two coaxial output cables. The external 24 VDC power supply required for operation must be purchased separately. Berkeley Nucleonics can recommend a compatible 24 VDC supply rated for the PVM-4210’s power requirements…
Yes, every new PVX high-voltage pulser ships with a standard accessory kit included at no additional cost. The accessory kit contains the cables and connectors needed for initial setup and operation. If you need replacement parts or additional accessories, Berkeley Nucleonics also sells accessory kits separately as spare parts. Contact us for accessory kit contents…
