Description
The SV Series of transient voltage suppressors are epoxy-coated square or
rectangular shaped leaded varistors with AC operating voltage ranging 60V to
680V. 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 customer 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.
