High Voltage Amplifiers (High Voltage Pulse Power Supplies)

The following products are high-voltage amplifier power supplies and high-voltage pulse power supplies.

The high-voltage amplifier power supplies are available in a variety of lineups, including ultra-fast response models with a slew rate of 1200 V/µs and ultra-compact module. The power supplies are ideal for solar panel evaluation, piezoelectric drive, beam deflection, electrophotographic processes, and various electrostatic tests.

Our lineup of high-speed pulse power supplies includes ultra-high-speed models with a repetition rate of 50 kHz, and models with an ultra-compact and lightweight design, which makes them ideal as power supplies for applying high-speed pulses in the electron beam and ion beam deflection, synchrotron radiation measurement, PMT, MCP, and so on.
