Description:
ZOV Series of varistors are square shaped components that feature a wide range of surge
current and energy absorption capabilities over an operating voltage range from 60 to 680
Vrms. There are two versions of these varistors.
The standard version is available in 5 model sizes from 23mm to 60mm, with single-pulse
(8/20 us) surge capabilities ranging from 15kA to 80kA. Offered in both block format and
rigid leaded construction, these varistors provide excellent protection against high-energy
transients such as inductively coupled lightning strikes, line switching load surges, and
other transient events where large amounts on current are present.
The second version features a broad range of custom parameters to meet specific over-voltage protection requirements.
Customers are given the opportunity to design the optimum varistor with minimum dimensions to satisfy a custom TVS
application. Available customized parameters are: non-standard AC/DC operating voltages, maximum surge current,
maximum dissipation power and the varistors shape, the dimensions being a function of required electrical parameters
and vice-versa.
Both of these groups are offered in two versions: epoxy coated with rigid terminals and metalized varistor blocks. The
first version is designed to provide secondary surge protection in outdoor and service entrance environments
(distribution panels), in computers and also in industrial applications for motor controls and power supplies for
equipment in oil-drilling, mining and transportation. The second version is intended for applications with special contact
or installation requirements. The electrode finish of these devices is solderable, and can also be used with pressure
contacts for stacking applications..
