High Power Pulse Modulator
The PowerMod™ HVPM solid-state, high power pulse modulator features fast rise and fall times of 5 ms for use in ion implantation, high energy physics, semiconductor and flat-panel display manufacturing. The PowerMod delivers up to 3 mW of peak pulses (20 kV, 150 A) at up to 30 kHz and insertion loss of less than 0.2 dB. Nominal pulse width is 1 to 100 ms and nominal pulse frequency is 0 to 30 kHz. Offering full internal self-protection against over-voltage and over-current conditions, the PowerMod is well suited for upgrading switch tubes or thyratron/PFN systems. The 19-inch rack-mountable unit is fully air-cooled and insulated and measures 19.0" x 30.0" x 24.0". Price: $50,000.
