Product description

This driver has a repetition rate from 0–200 kHz, an output voltage of 0–7.5 kV, rise and fall times of 10–15 ns with pulse widths of 100 ns–5 μs. The driver produces a top-hat waveform with fast-rising and falling edges.

A built-in digital voltmeter allows you to set the output voltage before applying it to the driver and separate high voltage enable/disable buttons are standard for added safety. A separate trigger on/off switch provides easy pulse control which also disables the high voltage at the rear panel output connectors.

The HVR-System comes in a standard 483 mm (19”) rack-mount enclosure which can also be used as a benchtop unit. It comes with forced air cooling for operation up to 50 kHz or water-cooled for higher repetition rates.
