TOS9213S/ TOS9213AS
1.2
Features
■
Two testing functions – DC withstanding voltage, and
insulation resistance tests
When connected to a DUT, the tester can perform these two different tests consecutively.
■
DC withstanding voltage test at 10 kV
(maximum output of 50 W)
The tester can perform DC withstanding voltage tests for a wide voltage range of up
to 10 k
V
(maximum output of 50 W and maximum duration of 1 minute). The tester
is equipped with a stable, low-ripple DC/DC converter with a voltage regulation of 1
% or less.
■
Improved measurement accuracy
The tester is equipped with a digital voltmeter for withstanding voltage testing with
an accuracy of ±(1 % of the r20
V
), and another for insulation resistance
testing with an accuracy of ±(1 % of the r1
V
). The two voltmeters display
measured values not only during a test but also during execution of a program.
The tester is equipped with an ammeter for withstanding voltage testing that features
accuracy of ±(3 % of the r5
μ
A
*

). Thus, it is capable of performing high-res-
olution tests, such as those that are required for P
V
panels. The two ammeters display
measured values not only during a test but also during execution of a program.

)
TOS9213S allows you to conduct an insulation resistance test at test voltage
range of 25
V
to 1000
V
(resolution of 1
V
) with resistance measuring range of
0.01 M
Ω
to 9.99 G
Ω
. Whereas, TOS9213AS allows you to conduct a test at
test voltage range of 25
V
to 1500
V
(resolution of 1
V
) with resistance mea-
suring range of 0.01 M
Ω
to 9.99 G
Ω
.

2: For TOS9213AS, if the test voltage setting exceeds 1020
V
, the resistance
measuring range is valid at rated current range of 50 nA to 0.1 mA.
