Functions
For measuring voltage and current
When the voltage at load is lower than the rated maximum output of AMP series, constant voltage and high speed operation is possible by sinking the output current with current sink feature.
As example of solar battery application, cell/panel voltage and current data can be obtained by logging the change of current sink by changing the voltage to solar battery cell/panel gradually. At that time with its high slew rate of 300 V/µs AMP can get more detailed sampling. AMP is a bipolar power supply with 0 crossing, and so, it can measure the output short current at 0 V. Moreover, it can output peak current of three times more than rated current (at DC). (see a chart)
OUTPUT RANGE
* Output rms must be within 2 A
Suitable for the trend to higher voltage for cell/panel evaluation
Voltage rating required for solar battery (panel) evaluation is getting higher and higher. AMP series added more lineups raging from ±600 V to ±30 kV to meet the demand for evaluation of higher voltage solar battery panel as well as evaluation of cell/panel with wider output range.

VOLTAGE RISE WAVEFORM
Achieving the slew rate of 700 V/µs at the actual load, AMP series offers a solution to "response delay in actual operation with the load".
In addition, the series is suitable for developing the high speed printers and the material evaluation testing.

| Slew rate | SR = 32 kV/40 µs > 700 V/µs |

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.
-LN: Cancellation of blackout protection
-LOc: Variation of current cutoff current setting value*
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 except for AMP-30B10 and AMP-40B20)
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.
