1. Introduction
Thank you very much for purchasing the High-speed High-voltage Amplifier T-HVA02 made
by Turtle Industry Co., Ltd.
The document describes use of the product, including its special features, how to use it,
handling instructions, and other information related to the product.
To use the product correctly you will need to be familiar with electric circuits because of the
special nature of the product. Any wrong usage or mishandling could result in not only
damage to the product but also lead to a serious accident. Please ensure you have
thoroughly read and understood this document in ensuring correct use of the product.
1.1 Product Outline
This product is a high-speed direct current amplifier with an output voltage of 600 Vpp. It has
a slew rate of 400V/µs and thus an excellent response to large amplitudes. The maximum
output current is 100 mA, thus incorporating a sufficient margin for the product to be used for
various purposes.
The offset adjustment is equipped with a fine-tuning dial function, thus supporting an output
offset of ±50 V.
1.2 Product Structure
The product package contains:
(1) Main Body of T-HVA02
(2) Operating Instructions Manual
(3) AC Cable
* If any of the above is missing ensure to contact our Service Support Section. (Refer to
page 11 for contact information.)

2. Names of Each Part
2.1 Front
Power Supply Switch
A push button switch used to supply power to the
amplifier.
When turned on the switch will light up in green.
Input Terminal Used to input signals. The input signals will be output
after the voltage has been amplified thirty times. Ensure
that a total of the output voltage from the input signals and
any signals due to the offset adjustment do not exceed
the range of ±300 V.
Output Switch A push button switch used to switch the output signals on
and off.
Lighting up red means signals are being output. Even
when the output has been set to off the built-in
high-voltage amplifier is still running, thus allowing it to be
monitored through the output monitor.
[Caution]
Even when the output is off about 1µA is being leaked.
Even when the output is off a capacitance of about 50 pF
is present between the output of the built-in amplifier and
the output terminal.

OffsetAdjustment Direct current voltage within the range of approx. ±50 V
can be added to the output voltage.
Output Monitor
Terminal
A monitor terminal for the output terminal. About 1/100
voltage of the output voltage will be output. The effective
bandwidth is less than 1 MHz.
To prevent the equipment from being damaged due to a
sudden voltage surge ensure to set the output switch to off before supplying any power.

Caution

Instruction Manual for T-HVA02

To avoid any hazardous situations make the connection after
ensuring there is no chance of a human body coming in contact with the high voltage side of
the voltage output (central terminal of BNC).
To avoid any hazardous situations ensure to ground it using a
GND terminal orAC inlet earth terminal.
Output Terminal This is where
signals are output with converted and
amplified voltage. High voltage is output here, thus
making touching the terminal in the center very
dangerous. Before connecting ensure sure to cut off the
power supply.
GND Terminal Connects to the internal signal GND. The internal signal
GND, the earth terminal for the AC inlet, and the case are
all common. To avoid any hazardous situations ensure to
ground it using a GND terminal orAC connection.
Fuse The fuse. If the fuse blows ensure to replace it with a 3A
time-delay (resistant to rush current) type fuse. When
replacing remove theAC input for greater safety.
AC Inlet Use with the accompanying AC cable to connect to an
AC100V power supply. Ensure to ground it for greater
safety. If it cannot be grounded at an outlet make an earth
connection using a GND terminal.

3. Description of Each Part
3.1 Input Terminal (INPUT)
The terminal is used to input the signals to be amplified. The input signals here will be
amplified 30 times and then output at the output terminal. A BNC connector is used here.
Ensure that a total of 30 times the input voltage that passes through the terminal and the
amount of the offset adjustment does not exceed ±300 V.
* The INPUT shield and OUTPUT shield sides have common potentiality (electrically
connected).
* The INPUT shield side and case have common potentiality (electrically connected).
* The input resistance at the input terminal is approx. 1 MΩ.
3.2 Output Terminal (OUTPUT)
The terminal is used to output the amplified voltage. The centerline is of high voltage, thus
making it very dangerous. When routing the output signal cables ensure to eliminate any
possibility of the human body easily coming in contact with the centerline.
The operating output voltage is from -300V to +300V.
* The OUTPUT shield side and INPUT shield side have common potentiality (electrically
connected).
* The INPUT shield side and case have common potentiality (electrically connected).
3.3 Output Switch (OUTPUT CONTROL)
This switch is used to enable or disable any voltage being output to the output terminal.
Pushing the switch will light up the button in red and enable output. If it does not light up the
output is off.
Even when the output is off ensure to keep the following in mind:
a) About 1µA of current will be leaking.
b) The internal amplifier and output terminal are connected with a capacitance of
about 50 pF. Depending on the frequency of the signals and the load some signal
voltage may get generated at the output. Even when the output is off ensure to
never touch the output central signal line.
To avoid hazardous situation ensure to never touch the output
terminal while power is being supplied, even if the output switch is turned off.
Warning

3.4 OffsetAdjustment (OFFSET)
A direct current voltage from -50 V to +50 V can be added to the output voltage.
A potentiometer with 10 rotations gets utilized here. It can be adjusted toward being positive
by turning it clockwise and toward negative by turning it counterclockwise. Ensure that the
total of 30 times the input voltage passing through the terminal and the amount of the offset
adjustment does not exceed ±300 V.
3.5 Output Monitor Terminal (OUTPUT MONITOR)
The monitor terminal for the output amplifier, which monitors the output terminal of the
internal amplifier and hence will be output when the output switch is set to off.
3.6 GND Terminal (GND)
The signal GND, the case, and the earthing wire of the AC cable are all common. Ground it
using the earth wire of theAC cable or this terminal.
3.7 Fuse (FUSE)
Use an AC125V (or more) - 3Atime delay fuse (resistant to rush current).
Size: φ6.3 x 30 mm
3.8 AC Inlet (95-105V AC)
SupplyAC100 V (50/60 Hz) power using the accompanyingAC cable.

4. Important Notes on Use
The internal amplifier has an overheating protection circuit. Once the temperature of the
output IC exceeds the threshold value the output will be turned off. If the protection has
been activated ensure to turn off the power supply and review the load on the product
or ambient temperature.
* The overheat protection will not recover until the power supply has been cut off.
Also has an overcurrent protection circuit. The protection circuit will be active while the
rated output current is flowing. If the protection does get activated ensure to review the
load on the product and signals.
Switching the output switch from off to on while the output level is high may activate the
overcurrent protection circuit and the output may not therefore be correct. Ensure to
turn the output switch on first and then increase the signal voltage.
