Application
Electrification of numerous industries is
prevalent. This is especially true for the
automotive industry. Voltage levels of next
generation powertrains or batteries in electric
carsand trucks are increasing. Currently, 800-
1200 V is made standard to achieve higher
efficiency and faster charging time. This poses
challenges to the safety of workers and
equipment during manufacturing and testing of
high voltage powertrain components using a
failsafe voltage threshold (for example 50
VDC).
Due
to
the
configuration, the HVT 300 series is suitable
for
numerous
industries
electrification components.

Such voltage occurs even when you touch a component or electrical connections of a component and are not electrostatically discharged. The damage that occurs to a component because of overvoltage usually cannot be detected immediately and does not become noticeable until after a longer operating period.
