SV Series — Special Medium Voltage Leaded Varistors
Description
The SV Series of transient voltage suppressors are epoxy-coated square or rectangular
shaped leaded varistors with AC operating voltage ranging 60V to 550V. There are two
versions of these varistors.
The standard version of square varistors, featuring extremely high-current and high-
energy capabilities and low clamping voltages, provides an increased level of protection
necessary for the transients expected in telecommunications and AC power networks.
Compared to standard disc varistors, SV series varistors realize electrical equivalent
values in smaller nominal dimensions.
In the custom version of the SV series, a customers can design (on their own or with our
help) an optimum varistor with minimum dimensions to satisfy a specific application. A
customer can choose from the following parameters: non-standard DC/AC operating
voltage, leakage current, clamping voltage, maximum surge current, energy absorption
level, maximum dissipation power, as well as shape (dimensions being the function of
required electrical parameters and vice-versa.
Features
