1-5 Additional Precautions for HV Amplifier Operation
When using this unit as a high speed and high voltage amplifier (except for DC mode operation),
make sure to wire HV output lines with minimizing its stray capacity.
Due to the HV amplifier characteristics, the output cable is not shielded. When the output cable has
some stray capacity against the ground (earth, metal objects, or like), the output will be sinusoidal or
step waveform and extra current will flow. As this current flows in parallel to the load, the following
phenomena may occur.
1) The rated maximum voltage or current cannot be obtained.
2) The waveforms at constant current operation or the current monitor are distorted or
deformed.

AMPS series
Capacitive Load
When operated with a capacitive load of more than 100pF (including floating capacity of output cable),
the output might oscillate. In such a case put a high voltage resister of 100Ω (0.1μF) to 1kΩ (1000pF)
in series to output. Please also note that with capacitive load the bandwidth is limited according to the
formula below.
Frequency Response
In case clear output waveform is required, please select a HV amplifier which has high enough
frequency bandwidth against required frequency.
In general 3 to 5 times more frequency bandwidth for sinusoidal waveform, and about 10 times more
for rectangular waveform, is required. In case of insufficient frequency bandwidth the output swing
shall be reduced, and also the phase difference be large, so some solutions, such as monitoring
output waveform, shall be required.
Rise Time (step responsibility)
Responsibility can be indicated with rise time (fig.2). Usually the rise time of amplifier of responsibility
(= bandwidth) fc (Hz) is given by a formula below.
tr ≒0.35/fc
The rise time “tf”is equals to “tr”.

Slew Rate
The responsibility of our high speed amplifier is determined with slew rate (SR). The step
responsibility of our amplifier is as shown in fig.3.
SR = △V/μS
In case of output amplitude is smaller the response time become shorter.
For example, AMPS-20B20 reach to greater than SR = 1200V/μs at maximum.
FOR SAFER OPERATION
Using this unit in a manner other than that specified may result in damage to its protective
functions..
1. For your safety, we recommend that an insulation plate that can withstand the used voltage on
the floor to operate the unit.
2. Operate the unit and load with your right hand, and do not touch anything with your left hand.
3. After turning off the voltage (even long time after turning off), be sure to ground the output more
than 10 seconds before you touch the load.
How to Carry
When carrying this unit, grasp the bottom of the front panel and rear panel.
The following figure shows in the case of AMPS-2B200, AMPS-5B80, AMPS-10B40, and AMPS-20B20.
Other models should be transported by more than one person or using carrying tools according to the
label on the top of the unit. Be careful not to pinch your fingers between the bottom of the unit and a floor
or table when placing it.
Do not hold the front panel handles in a way applying a heavy load on them.
Failure to do so may cause damage to the unit or injury.

1-6 Troubleshooting
In case no output voltage:
1. Check input voltage is correct
Input voltage: 230Vac ±10%, 50/60Hz, single phase
External control voltage: –10V to 10V
The output voltage will be limited if voltage out of the above range is input
If the output waveform is abnormal, check whether or not the external control voltage is out of the
specified range.
2. Check whether or not the overcurrent protection is activated.
(For details, refer to [4-9-3. Overcurrent protection] on page 18.)
3. Check whether or not the over temperature protection is activated.
(For details refer to [4-9-4. Over temperature protection] on page 18.)
In case discharging sound hears at the HV output section:
1. Check whether or not the plug section of the HV connector (the pointed section by the arrow
mark in the figure) is dirty. If the plug section of the HV connector is used with dirt on it, discharge
may occur within the connector. Wipe it with liquid such as alcohol, and dry it well before use.
NOTE: At operating frequencies a few kHz or more, the operating sound of the amplifier may hear from
inside of the unit, but this is not abnormal.
