Ultra High Slew Rate 1200 V/μs
The AMPS series is a line of high-performance High Voltage Amplifiers offering an exceptional ultra-high-speed response with a slew rate of 1200 V/μs. This series includes models up to ±30 kV as well as high-current models capable of delivering a 4 A peak current at ±0.6 kV, accommodating a wide variety of load conditions. All models feature true four-quadrant operation (bipolar power supply), enabling both power sourcing and sinking. This makes them ideal for cutting-edge R&D applications requiring precise waveform output, such as ion beam and electron beam deflection in semiconductor manufacturing equipment, and various material and dielectric strength tests. The series combines the high reliability synonymous with Matsusada Precision with a compact and sophisticated design for easy integration into laboratories and systems.
FEATURES AND BENEFITS
- Six Models ±0.6kV to ±30kV
- High Peak Current Output
Ultra High Slew Rate 1200 V/μs
±10 kV and ±20 kV models have achieved a twofold increase in response speed, reaching a slew rate of 1200 V/μs. Laser modulation and beam deflection at unprecedented high speed are possible.
High-Speed Response of Frequency Bandwidth 100 kHz
The 100 kHz frequency bandwidth under actual load conditions resolves the common issue of a slowed response time in real-world operation.
Ideal for high-speed beam steering and advanced material evaluation testing.
Model: AMPS-0.6B2000 (at rated load)
For Measuring Voltage and Current
When the voltage at load is lower than the rated maximum output of AMPS series, constant voltage and high speed operation is possible by sinking the output current with current sink feature.
For example, in ceramic and electrophotography development, the current sink feature enables rapid discharge of capacitive loads and smooth de-electrification.
Peak current (1 ms) output is twice the rated DC current (see right figure, AMPS-10B40 and AMPS-20B20 are three times the rated current), the rise characteristics with capacitive loads can improve.
(AMPS-0.6B2000)
* Output rms must be within 2 A

High voltage output cable 5 meters length (more than 2 kV models)
When using a cable 5 meters in length, phenomena such as reduced slew rate, slower response speed, or output waveform distortion are more likely to occur. Please use this configuration with caution. For details, please refer to "For capacitive load and discharge load".
* These options can be chosen only once, either. Selecting multiple options is unavailable at the same time.
How to Order
When placing an order, please add the option code(s) after the model name. If adding two or more options, omit the “-L” from
the second and subsequent option codes, and list them in alphabetical order, with the output cable length option placed at the end.
