The UltraMOV™ Metal Oxide Varistor Series is designed
for applications requiring high peak surge current ratings
and high energy absorption capability. UltraMOV™
varistors are primarily intended for use in AC Line Voltage
applications such as Surge Protection Device (SPD),
Uninterruptable Power Supplies (UPS), AC Power Taps,
AC Power Meters, or other products that require voltage
clamping of high transient surge currents from sources
such as lightning, inductive load switching, or capacitor
bank switching.

These devices are produced in radial lead package
sizes of 7, 10,14 and 20mm and offered in a variety of
lead forms. UltraMOV™ varistor are manufactured with
recognized epoxy encapsulation and are rated for ambient
temperatures up to 85ºC with no derating. This Series is
LASER-branded and is supplied in bulk, ammo pack (fan-
fold), or tape and reel packaging.
