ELECTRICAL SAFETY TESTERS

The Electrical Appliance & Material Safety Low (Japan),
UL (U.S.A.), CSA (Canada), VDE (Ger many) and BS
(U.K) are some major examples of safety standards in
use throughout the world that require the performing of
withstanding voltage testing. For this reason, it is
necessary to confirm for what portion of what standard
testing is to be performed when purchasing a
withstanding voltage tester . Although the 500 V A capacity
withstanding voltage testers av ailable from KIKUSUI can
basically be applied to tests specified in all safety
standards, we recommend that you consult with us prior
to purchase in order to select the model that best
matches your specific application.

TOS9200 SERIES

Withstanding Voltage and Insulation Resistance Tester

Perfect design for System Operation, introducing our top of the
line of Withstanding Voltage / Insulation Resistance Testers

TOS9201(AC/DC)

TOS9200(AC)

Capable of performing withstanding voltage and insulation
testing in comply with safety standards, including IEC, EN,
VDE, BS, UL,CSA, JIS and the Electrical Application and
Material Safety Law (Japan)

The TOS9200 Series has been developed to meet a wide diversity of
customer needs. Including the refinement and enforcement of Kikusui’s
former series, its specifications reflect the results of detailed study of
our large database of user’s requirements including special orders and
modifying specifications.
The TOS9200 Series consists of four products the testers TOS9200 and
TOS9201, and the high-voltage scanners TOS9221 and TOS9220.
The TOS9200 is equipped with AC withstanding voltage and insulation
resistance testing functions, while the TOS9201 has a DC withstanding
voltage testing function in addition to these two functions. The power
block, a core component, employs a high-efficiency switching power
supply and a switching amplifier based on PWM systems. These features
realize high power and enhanced stability, as well as reducing the size
and weight of the unit. When combined with the earth continuity tester
TOS6200, the TOS9200 Series integrates three or four types of tests in a
single process.
Furthermore, when used together with the high-voltage scanner
TOS9220/9221 (equipped with a contact check function), the tester is
capable of automatically checking test points for up to 16 channels,
thereby facilitating a safe, reliable automatic testing system.

TOS9200 SERIES

Withstanding Voltage and Insulation Resistance Tester

Basic performance

Three functions - AC withstanding voltage testing, DC
withstanding voltage testing and insulation resistance testing

The TOS9200 can perform AC withstanding voltage tests and
insulation resistance tests, while the TOS9201 can also conduct
DC withstanding tests. Once connected to a device being tested,
the TOS9201 executes an AC withstanding voltage test, DC
withstanding voltage test, and insulation resistance testing in
succession in one process.

AC withstanding voltage testing at 5 kV and 100 mA

Equipped with a high-efficiency switching power supply in its high­voltage power block, a PWM-based switching amplifier and a 500
VA high-voltage transformer, the TOS9200/TOS9201 realizes a
maximum output of 5 kV/100 mA (continuous output for 30 minutes),
or 2.5 times the output of Kikusui’s former models. At a test voltage
of 500 V or more and an upper current of 100 mA, or greater the
tester instantaneously satisfies the requirements of a short-circuit
current of 200 mA or more which is required by the IEC standard *.
In addition, the tester ensures a load effects of 30% or less and
the generation of a consistent 50 Hz/60 Hz test voltage free from
the affect of the supply voltage. These features eliminate the need
to readjust the output voltage once the test voltage is preset.
*Continuous outputs are impossible because the output is cut off if
an overcurrent is detected.

DC withstanding voltage testing at 6 kV and a maximum output
of 50 W

The TOS9201 permits DC withstanding voltage testing at up to 6
kV *. The tester is equipped with a stable, low-ripple DC/DC
converter with a load factor of 1% or less.
*Maximum output of 50 W for up to 1 minute.

Insulation resistance testing at 25 V to 1000 V and 0.01 MΩ to

9.99 GΩ

The test voltage can
be set to 25 V through
1000 V at a resolution
of 1 V. Insulation
resistance covers a
wide measurement
range from 0.01 MΩ to

9.99 GΩ *.

Test voltage Resistance measurement range

25V 0.03 MΩ to 500 MΩ

500V 0.50 MΩ to 9.99 GΩ

1000V 1.00 MΩ to 9.99 GΩ

A single unit of the TOS9200/9201 is capable of handling all test
voltages required by JIS C 1302 1994 (Insulation Resistor Meter)
and fully meets the JIS requirements.
*At a maximum rated current of 1 mA to 50 nA.

Enhanced measurement accuracy

The TOS9200/9201 is provided with a digital voltmeter for
withstanding voltage testing at an accuracy of ±(1% of reading +
30 V) and another one for insulation resistance testing at an
accuracy of ±(1% of reading + 1 V). Measured values are displayed
not only during a test, but while a program is being executed. A
digital ammeter with an accuracy of ±(3% of reading + 20 µA) is
also provided for withstanding voltage testing. Kikusui’s
predecessors had a highest measurement resolution of about 1
mA , with an accuracy of ±5% of the upper cutoff current when it is
set to 100 mA. In contrast, the digital ammeter allo ws the T OS9200/
9201 to make measurements at an accuracy of ±(3% of reading +
20 µA), even if the upper current is set to 100 mA. The ammeter
displays measured values while the program executes, as well as
during an AC or DC withstanding voltage test.

TOS9200 SERIES

Withstanding Voltage and Insulation Resistance Tester

Diverse functions

Rise-time control function

In AC withstanding voltage testing, DC
withstanding voltage testing and
insulation resistance testing, you can
apply a voltage gradually to reach the
test voltage, instead of applying the test
voltage directly at the start of a test. The
voltage increase time can be set to 0.1
s through 99.9 s at a resolution of 0.1 s,
and to 100 s to 200 s at a resolution of 1 s. The start voltage is also
adjustable between 0% and 99% at a resolution of 1%.

Fall-time control function

In AC withstanding voltage testing, you
can gradually decrease the test voltage
after a PASS judgment. The v oltage f all
time is adjustable between 0.0 s and

99.9 s at a resolution of 0.1 s, and
between 100 s and 200 s at a resolution
of 1 s.

Offset cancel function

In AC withstanding voltage tests that require high sensitivity and high
voltages, currents flowing into the stray capacity of the test lead wire,
jigs, and other components can cause measurement errors. The
TOS9200/9201 features a function to cancel these offset currents.

Voltage hold function

During measurement, this function allows you to hold the value of the
voltage measured at the end of an AC or DC withstanding voltage test,
as long as the test results are being displayed. When combined with
the rise-time control function, this function enables to observe the
insulation breakdown voltage.

Memory function

Up to 100 test conditions used in AC and DC withstanding voltage
testing and insulation resistance testing, such as the test voltage,
judgment value and test time, can be stored with a specific name. For
instance, you can store the name of an applied safety standard and
the destination of the product to be tested. If test conditions are preset,
operator can recall relevant test conditions simply by entering the
memory number. If y ou pre viously assigned a special name to each of
these test conditions, operator can check recalled test conditions by
name. The memory function allows you to recall test conditions not
only through the recall operation on the front panel, but also by remote
control.

Maximum Leakage current and minimum resistance hold
function

By selecting “MIN/MAX Mode” in the measurement mode settings, y ou
can hold the maximum current in withstanding voltage testing and the
minimum resistance after the judgment wait time in insulation resistance
testing. These values are shown on the tester’s displa y. They can also
be read back via interface (GPIB or RS-232C).

Output voltage monitoring function

When the output voltage deviates from ±(10% of setting + 50 V), the
monitoring function activates to suspend the test, thus ensuring highly
reliable testing.

Current detection response speed adjustment function

This function switches current detection response speeds for UPPER
judgment by adjusting the integrated time constant of the current
detection circuit. Three modes are available for the integrated time
constant: SLOW (about 40 ms), MID (about 4 ms) and FAST (about

0.4 ms). SLOW mode is used in normal operations. MID and FAST
modes are more effective in detecting a discharge occurring
instantaneously or containing a large number of frequency components.
They are also useful for withstanding voltage tests of test devices that
insulation likely be breakdown, such as small electronic components.

8

Program function

By coordinating test conditions stored in an AC withstanding voltage
test, DC withstanding voltage test, and insulation resistance test,
operator can sequentially run tests that comprise up to 100 steps. When
used together with the earth continuity tester TOS6200, the TOS9200
Series permits continuous tests combining test conditions stored in
the TOS6200, as well as on the TOS9200 itself. Sequential tests are
possible, for e xample, on AC withstanding v oltage, insulation resistance,
DC withstanding voltage, and earth continuity, in order. The TOS9200
Series stores up to 500 steps and 100 programs, which can be recalled
through the recall operation on the front panel or by remote control.

REMOTE connector & SIGNAL I/O connector

The REMOTE connector on the front
panel is intended exclusively for
Kikusui’s options (remote control/test
probe). It allows start and stop
operations by remote control. The SIGNAL I/O connector on the
rear panel permits operator to recall panel memory and program
memory contents by remote control, as well as controlling start
and stop operations. Seven different signals are output from the
SIGNAL I/O connector through the open collector.

TOS9221

TOS9220

The high-voltage scanner TOS9220/TOS9221 has a function that
distributes the test voltage provided by the TOS9200/9201 to
multiple test points. Up to four channels can be used for outputs
on this scanner. Each channel can be set to one of the three
electric potential modes – HIGH, LOW, or OPEN. Operator can
conduct AC/DC withstanding voltage and insulation resistance tests
on any of the four test points. Fur ther more, up to four scanners
can be connected to the tester, allowing a maxim um of 16 channels.
The T OS9200 is equipped with a “contact check function” to check
the contact between the output of each channel and a test point.
These features ensure highly reliable and labor-saving withstanding
voltage and insulation resistance tests for electrical and electronic
equipment with multiple test points.

Operation of the high-voltage scanner

On the TOS9200/TOS9201, you can select an electric potential
mode for each channel – HIGH (high voltage side), LOW (low
voltage side), and OPEN (open mode). The high-voltage scanner
permits AC/DC withstanding
voltage or insulation resistance
tests on any of the four test
points A to D. For instance, you
can set CH1 (test point A) to
HIGH, CH2 (test point B) to
OPEN, and CH3 (test point C)
