TOS9200/9201 Preface P-1
Preface
Outline
The TOS9200 and TOS9201 are withstanding voltage/insulation resistance testers.
The TOS9200 can perform AC withstanding voltage testing and insulation resis-
tance testing. The TOS9201 can perform DC withstanding voltage testing, in addi-
tion to AC withstanding voltage testing and insulation resistance testing. Both can
operate at up to 5 kVAC/100 mA (for up to 30 minutes) in AC withstanding voltage
testing, and up to 6 kVDC (at a maximum output of 50 W for up to 1 minute) in DC
withstanding voltage testing. These models are capable of performing withstanding
voltage testing on electronic equipment and components in accordance with safety
standards, including IEC, EN, VDE, BS, UL, CSA, JIS, and the Electrical Appli-
ance and Material Safety Law (in Japan.)
The high-voltage block features a high-efficiency switching power supply and a
PWM-based switching amplifier. This ensures high and stable output extremely
resistant to power-supply and load fluctuations. The TOS9200 and TOS9201 are
almost 30% smaller and lighter than Kikusui’s previous models.
For insulation resistance testing, these testers are compatible with 25 V to 1000 V
(at a resolution of 1 V) and 0.01 MΩto 9.99 GΩ(at a maximum rated current of 1
mA to 50 nA).
Once connected to a DUT, the TOS9200 and TOS9201 can not only perform AC
withstanding voltage tests, DC withstanding voltage tests, and insulation resistance
tests separately, but can also conduct these tests consecutively using the program
function. When combined with the high-voltage scanner TOS9221/TOS9220, each
tester can operate using four channels. The tester can be connected to four scanners,
thus permitting the connection of a total of 16 channels. Further, when used together
with the earth continuity tester TOS6200, the TOS9200 and TOS9201 can also be
applied to safety tests such as earth continuity tests.
The TOS9200 and TOS9201 are equipped with GPIB and RS-232C as standard fea-
tures, making them highly applicable to a variety of automatic testing systems that
require greater safety and reliability.

Features
■Three testing functions – A C withstanding v olta ge, DC
withstanding v olta ge, and insulation resistance tests
The T OS9200 performs A C withstanding v oltage testing and insulation resistance
testing. The T OS9201 conducts A C withstanding v oltage testing, DC withstanding
v oltage testing, and insulation resistance testing.
When connected to a DUT , the tester can perform these three dif ferent tests consec -
uti v ely .
■A C withstanding v olta ge test at 5 kV/100 mA
The high-v oltage po wer block is equipped with a high-ef fi cienc y switching po wer
supply , a PWM-based switching amplifi er , and a high-v oltage 500 V A transformer ,
realizing a maximum output of 5 kV/100 mA (up to 30 minutes), 2.5 times that of
Kikusui’ s former counterparts. F or an upper limit of 100 mA or more at a test v olt -
age of at least 500 V , the T OS9200 and T OS9201 conform, though only for an
instant, to IEC requirements for short-circuit current of 200 mA or more. (The
testers do not allo w continuous output, as the output is cut of f when an o v ercurrent
is detected.) In addition, these testers generate a consistent test v oltage of 50 Hz/60
Hz, independently of the po wer v oltage, and contain the v oltage re gulation to less
than ±3 %. This mak es it unnecessary to readjust the output v oltage when a test
v oltage has been preset.

■Full y pr ogrammab le GPIB and RS-232C interfaces as a
standar d f eature
All functions e xcept for the PO WER switch, KEYLOCK, and program e x ecute
(A UT O) functions, are remote-controllable. T est conditions such as the test v oltage,
judgement v alue, and test time can be controlled remotely in A C and DC withstand -
ing v oltage and insulation resistance tests. Measured v alues and measurement
results can also be read back by remote control. The GPIB and RS-232C interf aces
pro vided as a standard feature smoothly interf ace the tester with a PC, sequencer ,
and other de vices.
■Fle xib le contr ol function realiz ed b y a high-v olta ge scanner
When combined with the optional high-v oltage scanner T OS9220 (5 kV A C/6
kVDC), the T OS9200/9201 can test multiple points in withstanding v oltage and
insulation resistance tests. Using the T OS9200/T OS9201 panel, each channel can be
set to a HI/LO/OPEN v oltage. One scanner can operate up to four channels. Up to
four scanners can be connected to the T OS9200/9201, enabling the simultaneous
operation of a total of 16 channels. The T OS9221 is equipped with a function for
detecting connections between the high-v oltage test leadwire and the DUT , thus
ensuring highly reliable testing.
■Rise-time contr ol function
In A C withstanding v oltage testing, DC withstanding v oltage testing, and insulation
resistance testing, a v oltage can be slo wly increased until it reaches a required test
v alue, instead of applying the required test v oltage to the DUT immediately after the
start of a test. The v oltage rise time can be set to 0.1 s through 99.9 s at a resolution
of 0.1 s, and to 100 s through 200 s at a resolution of 1 s. The start v oltage, which is
applied at the start of a test, can be set to 0 % to 99 % of the test v oltage at a resolu -
tion of 1 %. Thus, the T OS9200/T OS9201 conforms to the requirement for the type
certifi cation test under the UL standard and the withstanding v oltage test under the
IEC standard that less than half of the test v oltage be applied initially and slo wly
increased for a specifi ed period of time before the test v oltage is reached.

■F
all-time contr ol function
F or P ASS judgement in A C withstanding v oltage testing, the test v oltage can be
decreased in increments. The v oltage f all time can be set to 0.0 s through 99.9 s at a
resolution of 0.1 s and to 100 s through 200 s at a resolution of 0.1 s.
■Disc har ge function
Generally , DUTs contain capaciti v e elements. Therefore, DUTs remain char ged
immediately after a DC withstanding v oltage test or insulation resistance test has
been conducted, resulting in the danger of electric shock. The T OS9200/T OS9201
has a function for forcibly dischar ging the DUT upon completion of DC withstand -
ing v oltage test or insulation resistance test.
■Enhanced saf ety
T o enhance safety , the T OS9200/T OS9201 is equipped with a number of de vices
and safety functions, including safe output terminals, a dischar ge function, and an
analog v oltmeter that constantly monitor the output-terminal v oltages. Such safety
measures also include a danger lamp that constantly monitors output-terminal v olt -
ages e v en when no test is under w ay and lights up when a v oltage is detected, in
addition to an interlock function that cuts of f output in coordination with an e xternal
de vice.
■Impr
o ved measurement accurac y
The T OS9200/T OS9201 is equipped with a digital v oltmeter for withstanding v olt -
age testing with an accurac y of ±(1 % of the reading +30 V), and another for insula -
tion resistance testing with an accurac y of ±(1 % of the reading +1 V). The tw o
v oltmeters display measured v alues not only during a test b ut also during e x ecution
of a program.
The testers are equipped with an ammeter for withstanding v oltage testing that fea -
tures accurac y of ±(1 % of the reading +20 μ A). Kikusui’ s pre vious testers had a
measurement resolution of approximately 1 mA and an accurac y of approximately
±5 % of the upper current that w as set to 100 mA. By comparison, the T OS9200/
T OS9201 can operate with an accurac y of ±(3 % of the reading +20 μ A) at an upper
current of 100 mA. The tw o ammeters display measured v alues not only during a
test b ut also during e x ecution of a program.
■Offset cancel function
In an A C withstanding v oltage test that requires high sensiti vity and high v oltage,
current fl o wing into the stray capacity of test leadwires and jigs tends to cause mea -
surement errors. The T OS9200/T OS9201 features an of fset cancel function that
cancels of fset currents such as stray currents.
■V olta ge hold function
During judgement, this function allo ws the tester to retain measured v oltages
recorded upon completion of a test, while it is still outputting the judgement results.
Combined with the rise-time control function, the v oltage hold function enables
detection of the dielectric breakdo wn v oltage.

P-6 Preface
TOS9200/9201
■Output v
olta ge monitoring function
When the output v oltage de viates from ± (10 % of the setting +50 V), the monitor -
ing function acti v ates to suspend the test, ensuring highly reliable testing.
■High operability
The T OS9200/T OS9201 is easy to operate, allo wing the operator to start using it
without dif fi culty . Featuring the T OS5000’ s high operability , the tester displays the
primary test conditions on the fi rst page of the menu, with the secondary test condi -
tions sho wn on the follo wing pages. T o set test conditions, simply use the cursor k e y
to choose from among the items displayed on the LCD, and then turn the rotary
knob . The function k e ys allo w you to jump to items to be set. During a test, the out -
put v oltage can be changed using the rotary knob .
■Sa ving 100 test conditions f or eac h test
One hundred test conditions, such as the test v oltage, judgement v alue, and test
time, can be set and named for each test of the A C withstanding v oltage, DC with -
standing v oltage, and insulation resistance. F or e xample, the name of the applicable
safety standard and the shipment destination of the DUT can be sa v ed. Ev en when a
change is made to the destination of a product or the name of the applicable safety
standard, there is no need to change the preset test conditions. T o recall these test
conditions, simply set the memory number . If such test conditions ha v e their o wn
name, the y can be confi rmed using that name. T est conditions can e v en be recalled
from outside.
■Pr
ogrammed test conditions
By confi guring the test conditions sa v ed for each test, 100 test steps can be per -
formed consecuti v ely .
When used together with the earth continuity tester T OS6200, the T OS9200/
T OS9201 inte grates the test conditions sa v ed in the earth continuity tester to per -
form continuous tests. T ests can be performed easily , such as on the A C withstand -
ing v oltage, insulation resistance, DC withstanding v oltage, and earth continuity , in
that order .
Up to 500 steps can be confi gured, with 100 programs storable, permitting recalls
e v en from outside.
■Remote-contr ol function and signal output function
Used e xclusi v ely for options, the DIN connector on the front panel enables the
remote control of start/stop operations, lik e its con v entional counterpart. Using the
SIGN AL I/O connector on the rear panel, start/stop operations can be conducted
and the panel memory or program memory can be recalled.
Se v en signals are output by the open collector through the SIGN AL I/O connector –
HV ON, TEST , P ASS, UPPER F AIL, LO WER F AIL, READ Y , and PR O TECTION.
These signals can be used together with the remote-control function to automate
testing and sa v e labor .
