TOS9213S/ TOS9213AS
1.1
Outline
The TOS9213S/ TOS9213AS (hereinafter referred to as “the tester”) is withstanding
voltage/insulation resistance tester. The tester can perform DC withstanding voltage
testing and insulation resistance testing. The tester can operate at up to 10 k
V
DC (at
a maximum output of 50 W for up to 1 minute) in DC withstanding voltage testing.
The tester is capable of performing withstanding voltage testing on electronic equip-
ment and components in accordance with safety standards, including IEC, EN,
V
DE, BS, UL, CSA, JIS, and the Electrical Appliance 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.
Because the tester boasts measurement accuracy that enables it to handle high-reso-
lution current measurements and judgements of values as small as tens of µA, it is
ideal for testing solar panels (photovoltaic panels) and other devices.
For insulation resistance testing, TOS9213S is compatible with the test voltage
range of 25
V
to 1000
V
(at a resolution of 1
V
) and the resistance measuring range
of 0.01 M
Ω
to 9.99 G
Ω
(at rated current range of 50 nA to 1 mA maximum),
whereas TOS9213AS is compatible with the test voltage range of 25
V
to 1500
V
(at a resolution of 1
V
) and the resistance measuring range of 0.01 M
Ω
to 9.99 G
Ω
(at rated current range of 50nA to 1 mA maximum, or at rated current range of 50
nA to 0.1 mA if the test voltage setting exceeds 1020
V
).
Not only can the tester make judgements using insulation resistance values, it can
also make judgments using measurements of the leakage current that flows through
the insulation resistance.
Once connected to a DUT, the tester can not only perform DC withstanding voltage
tests, and insulation resistance tests separately, but can also conduct these tests con-
secutively using the program function. When combined with the high-voltage scan-
ner 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 chan-
nels. Further, when used together with the earth continuity tester TOS6200, the tes-
ter can also be applied to safety tests such as earth continuity tests. (When combined
with the scanner, the output voltage is up to 6 k
V
.)
The tester is equipped with GPIB and RS-232C as standard features, making them
highly applicable to a variety of automatic testing systems that require greater safety
and reliability.
