Description
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.
