1Overview
The Berkeley Nucleonics PVP-Series delivers regulated high-voltage direct current for demanding test, calibration, and production environments. Each unit is controlled by a dedicated microcontroller and FPGA, so voltage and current are held to tight tolerances digitally rather than through analog trim. The result is a source that settles fast, drifts little, and repeats reliably from one run to the next.
The family covers a wide envelope. Output voltage reaches 30 kV DC, power is offered in 500 W, 2 kW, and 3 kW classes, and current extends to 2 A on the lower-voltage models. Polarity can be electrically reversible, fixed positive, or fixed negative, and selected models offer a floating, potential-free output for applications that cannot tie to earth.
Every PVP-Series ships ready for the bench or the rack. A 3.5-inch color display and three-button menu handle local operation, while Ethernet, RS232, and a full SCPI command set make the supply straightforward to fold into an automated test sequence.
2Key Features
- Fully digital regulation. Microcontroller and FPGA control of both voltage and current loops for repeatable, low-drift output.
- Wide range. 1.5 kV to 30 kV DC across 500 W, 2 kW, and 3 kW power classes, with current to 2 A on lower-voltage units.
- Flexible polarity. Electrically reversible (positive or negative, earth-referenced) or floating, potential-free output on selected models.
- Active power factor correction. Wide-range single-phase AC input keeps the line clean across the operating window.
- Local and remote control. Color display with structured menus, plus Ethernet, RS232, and SCPI for full automation.
- Built for integration. 19-inch rack mount or benchtop in a 2U enclosure, with an integrated benchtop adapter.
- Retrofittable options. Ramp control and arc detection can be added in the field.
