PFNs/ MODULATORS

PFNs provide high power pulse generation and are used in lasers, high power medical oncology systems and transmitters for radar. RFI also supplies complete pulse sub-systems where the high voltage modulator contains the power supply, filament transformers, charging and discharging components, reactors and pulse transformers.
