4 User’s Manual TOS93 Series
The TOS93 series is a electrical safety analyzer that can
perform several types of safety tests on electronic devices
and components. The available types of safety tests
include withstanding voltage test, insulation resistance
test, earth continuity test, leakage current test (touch cur-
rent test, and protective conductor current test, patient
leakage current test).
Different models are available according to the combina-
tion of tests you require, so a single unit is enough to cover
your various safety test needs.
The product is suited to (1) research and development
installations, (2) test facilities for quality assurance testing
and standard certification, and (3) manufacturing lines.
TOS93 Series Lineup
Features
Diverse lineup of products
A diverse lineup of products is available for the various
combinations of test required in production lines to
accommodate a variety of needs. Tests can be per-
formed in accordance with the requirements of safety
and electrical standards and ordinances such as IEC,
EN, BS, VDE, UL, CSA, GB, and JIS.
Dielectric breakdown detection sensitivity settings
Safety standards define that corona discharge and par-
tial discharge are not dielectric breakdown. This product
allows you to adjust the detection sensitivity of EUT’s
dielectric breakdown during withstanding voltage testing
to support a wide range of settings from those that do
not detect corona discharge or partial discharge to those
that do. Failure analysis that were not possible with pre-
vious Kikusui withstanding voltage testers is now possi-
ble.
Support for AC/DC earth continuity test up to 40 A
(TOS9302, TOS9303, TOS9303LC only)
The newly developed amplifier a broad range of tests
from AC earth continuity test of general home electric
appliances to DC earth continuity test of EV-PV sys-
tems.
A single unit for safety standard testing
(TOS9303LC only)
A single TOS9303LC, which includes all functions nec-
essary for AC/DC withstanding voltage testing, insula-
tion resistance testing, AC/DC earth continuity testing,
and leakage current testing, can perform the entire set
of safety standard conformance tests.
