Ultra high slew rate 1200 V/µs

±10 kV and ±20 kV output models achieved the existing double high-speed response of slew rate 1200 V/µs. Laser modulation and beam deflection at unprecedented high speed are possible.

slew rate

High-speed response of frequency bandwidth 100 kHz

Frequency bandwidth with actual load is as high as 100 kHz, and solve the problem of "When actual operation with load, the response become slow." Ideal for high speed printer or material evaluation testing.

Amplifier AMPS Series Frequency response

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 are possible by sinking the output current with current sink feature. As example of the development of ceramic and electrophotography process, by current sink, it is possible to absorb the voltage of a capacitive load quickly or to perform diselectrification smoothly.

Peak current (1 ms) output is twice the rated DC current (see a figure, AMPS-10B40 and AMPS-20B20 are three times the rated current), the rise characteristics with capacitive loads can improve.

Options

-LC: Current Limit *

The output is not cut off but it is limited in the event of lowering output voltage at overcurrent level.

-LCc: Variable current limit *

The output is not cut off but it is limited in the event of lowering output voltage at overcurrent level. Using the potentiometer on the front panel, the limit current value can be adjusted in the range of 10% to 105% of the rating.

-LCx: Variation of current cutoff + Variable current limit *

Both of -LOc (Variation of current cutoff) and -LCc (Variable Current limit) are switchable.

NOTE: As for models with -LCx option, the CE marking Low Voltage directive is not applicable.

-LN: Cancellation of blackout protection

-LOc: Adjustable cut-off current setting *

Using the potentiometer on the front panel, the limit value to cut off the output current can be adjusted in the range of 10% to 105% of the rating.

-L(5m): HV output cable 5 m (more than 2 kV models)

When using a cable with 5 m long, phenomena such as lower through rate or response speed or output waveform distortion may occur easily. Be careful to use it.

For details, refer to "Capacitive load".

* These options can be chosen only one either. Selecting multiple options is unavailable at the same time.

Tech Notes

Capacitive Load

When a capacitive load is more than 100 pF (including a stray capacitance of output wire), the resonance in the output may occur. In that case, install 100-ohm (@0.1 μF) to 1000-ohm (@1000 pF) of high voltage resistance in the output in series. Please note that the frequency band will be limited as the formula written in the right figure when an amplifier is used with a capacitive load.
In addition, when an amplifier is used for the use such as a corona discharge, the current which is higher than rating will flow and it will affect the amplifier badly. In this case, as well as the time to use an amplifier with a capacitive load, please install the output resistance and limit the current.

* Please avoid continuous inputting of high frequency signal which reduces output frequency of an amplifier. An amplifier will be broken because of increase of internal loss.

This image explains frequency band when a capacitive load is connected.
